Genetic mutation

Hey guys - I'm back with another blog post.  Today we will be talking about genetic mutation. A genetic mutation is a change in the cells DNA which can have good or negative effects. For example, Godzilla was a genetically mutated lizard. That is a example of a positive mutation.

A gene is a unit of heredity.  Genes are important because they give you all your feature like eye color or body shape. When your genes get messed up the changes can be good or bad (most of the time bad). Genetic mutation happens mostly when your cells split. It is extremely hard to live if you have a bad genetic mutation. Some will effect how fast you age and others might effect what your body looks like. You can even have two heads or two bodies!  Just because this stuff can happen to your DNA, doesn't mean your cell will let it stay there. In your cells you have DNA repair and it will get rid of the mess up in the DNA as soon as it can. If the DNA repair can find the problem it can become permanent.







Even though many bad thing can happen to you in genetic mutation, some good things can happen to you too. For example, say you are a bird and you get an extra long beak. You would be able to get food more effectively than if you had a small one you would have had without the mutation. If you get the long beak, you would have a better chance of passing it down to your kids.


Here are some examples of things that cause mutations: DNA doesn't copy the accurately, external influences such as exposure to a chemical such as tobacco, deletion occurs in other words a section of the DNA is deleted or insertion meaning extra code is added to the DNA. 


Well, that's all for now.  Bye.

RNA

Hey guys im back and today we will be talking about RNA. RNA is not dna but it works together with dna to creates proiteins I will be explaining how everything work and how it is differnt from dna lets begin.

RNA is also known as ribonucleic acid.  It is made in the nucleus on a DNA pattern. It is a type of nucleic acid that carries codes for making proteins from the nucleus to the ribosomes.

It works with DNA to make ribozones which gives us most of our features like hair color or size. They work together by the DNA making info for the RNA to take, translate and give to the ribozones to make proteins.

RNA has the bases adenine (A), guanine (G) and cytosine (C) like DNA, but has the base uracil (U) instead of thymine (T). The sugar-phosphate molecules in RNA contain the sugar ribose, not deoxyribose.

All living things have RNA and DNA.  RNA is important because it carries the codes for making proteins. Proteins build cells and tissues or work as enzymes.  A ribosome is a small cytoplasmic structure on which cells make their own proteins.

rRNA makes up ribosomes.  The mRNA is the messenger which takes the info from the DNA and brings it to the tRNA which translates it so that the ribozones can read it and create proteins. The thing that make the RNA different from DNA is that DNA makes the info but RNA takes the info and brings it to the ribosomes.

Well thats all for now I hope you learned that Dna wouldnt work without Rna. So thats all for now sell you later.

D.N.A

Hey guy I'm back with another blog post and today we will be talking about D.N.A. Without these we wouldn't be here. lets begin.


DNA is basicly a blue print to everything it the world.  DNA is deoxyribonucleic acid. It is the genetic material of all organisms. It is made up of two twisted strands of sugar-phosphate molecules and nitrogen bases. It help us grow and function.

Rosalind Franklin discovered that DNA is two chains of molecules in spiral form. James Watson and Francis Crick made a model of a DNA molecule.

DNA looks like a twisted later. The sides of the ladder are made up of sugar-phosphate molecules. The four kinds of nitrogen bases are adenine, guanine, cytosine and
thymine. The amount of cytosine is equal to the amount of guanine and the amount of adenine is equal to the amount of thymine. So, Cytosine is always paired with guanine and adenine is always paired with thymine.

Before mitosis the chromosomes are duplicated and the amount of DNA
in the nucleus is doubled. The two sides of DNA unwind
and separate. Each side then becomes a pattern on
which a new side forms. The new DNA has bases that are
identical to those of the original DNA and are in the same
order.

A sample of a suspect’s DNA can be compared to evidence from the crime scene to help determine if the suspect is guilty. If there isn’t a suspect, evidence from
the crime scene can be compared to a general database of criminals the police may maintain. Crime scene evidence can also be compared to other crime scene DNA information the police may have on file to link two crimes
together.

Mitosis

Hey guys im back with another blog post and today we will be talking about. Mitosis a way a cell can reproduce. Without it we would be dead. lets Go











There are sic phases to this prosses. Interphase, Prophase, Metaphase, Anaphase, telophase and cytokines. In the Inter phase the chromosome in the cell are dubled and stat to appear as threadlike coils (chromotion).  The chromosomes and there copie change to sister chromatids at the end of this phase. The next  phase is the prophase. In this phase mitosis begins which means the cell are starting to divide. Centrioles appear and the start moving to opsite ends of the cell. Spinder appear between the centrios.




The third stage is metaphase. In this stage the chromatide attach to the spindal fiber. In the anaphase the chromatide seperate and start to appear as chromatin. In telophase two brand new nuclei form. The chromosomes apear as chromatin rather than rods. At the end of this phase mitosis in. In cytophase the cell membrain moves inward to creat to new cells, each with its own nuclei that have the exact same chromosomes. Well thats all for now bye

Man Smuggles 40,000 Piranhas

Hey guy I am back with another blog post and today I will be talking about a man smuggling about 4000 piranhas into New York City. Piranhas are aggressive territorial fish that live in fresh water and have razor sharp teeth. They live in South America. There are about 20 known species and the fish are illegal or restricted in 25 states in the U.S.A. because of the danger they can pose to people.








A man in New York pleaded guilty for the smuggling of 39,548 Piranhas. The man was forced to pay $70,000 in fines and restitution. His company was also put on probation for two years. New York did not allow these fish in because of how dangerous they are and how they can hurt the wildlife, including humans.

My Thoughts
I think that the man paying a fine was a good thing. I thought that he should not have taken these animals from their home and therefor he should be punished.

Viruses

PS: I like luigi

Hey guy I'm back with another blog post and today we will be talking about the viruses. You might already know some stuff about viruses but now I am going to tell you what you don't know.







even Mario fights viruses
#Dr. Mario

First off a Virus is "an infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host." Viruses can get inside your body and make you sick. A virus cannot move, is not alive, cant breath, cant eat and cant drink water. When a virus gets inside your body it can do two thing A: can find its host cell and start multiplying or B: it can stay there and do no harm which are called latent viruses. Some illnesses include chicken pox, the common cold and the flu.

 

 

Now that you know that viruses ain't that good but now I will tell you are one weapon. Vaccines are the reason we are able to survive the virus. Vaccines are made using week created viruses that will go into your body so you imunsistem can kill them and be ready for the real thing.






The last thing I will be talking about is a man named Dr. Edward Jenner's. This man saved peoples life's by making the vaccine which is still used today. When he said he found a cure the other doctors lafed at him, but when he proved he was correct he was loved by the other doctors.

The Other Side of BACTERIA!!!!!!!!!!!!!!!!

I look into your soul.

He guys I am back with another blog post and today I will be talking about Bacteria. :) Now there are some good parts to bacteria like the fact we would not be here without them. Lets go
















Bacteria is good for many different ways like, Being the first life on earth, making food good and ever helping our body function. Some are bad tho very very bad. So people where like we need to stop this and invented the antibiotics. dundundahhh. These kill bacteria but there is a catch. People have been using less because the bacteria has been able to adapt to the antibiotics. Now you cant use Antibiotics without a doctors description. Bad bacteria can cause diseases like Streptococcus pneumoniae: which infects the lungs causing  pneumonia and is spread by coughing. Another is Gnorrhea:This disease is a sexually-transmitted disease and is caused by a bacterium of this type. One symptom is a pussy discharge from the genital area. As you can see you want to fight bacteria at all cost but not all bacteria is bad. So are on the light side of the force. In fact more than me than 90 percent of all nitrogen fixation is effected by them. This is caused by nitrogen-fixing bacteria.






Now I shall tell you what is bacteria. First of all the way that bacteria reproduce is by using fission which is breaking into to bacteria exactly the same as the first :(). This processes if called asexually and the other is sexually which is when there are two. Some bacteria need to get there food wile other can make there own by using photosynthesise.
