DNA Function & Structure


Link: https://www.youtube.com/watch?v=zwibgNGe4aY

DNA is something that everyone and everything has. DNA stands for Deoxyribonucleic Acid. DNA was discovered in the 1950's by James Watson and Francis Crick. The structure is a double helix also known as a twisted ladder because of the way it looks.  

Also DNA is genetic material that carries information for making proteins, which is made up of nucleotides. The nitrogenous bases are:
- Adenine (A)
- Guanine (G)
- Thymine (T)
- Cytosine (C)
A always pairs with T, and G always pairs with C 

What I personally learned about the DNA function and shape was that the hydrogen bonds are weak so it can "unzip" and for it to replicate, and thats how we survive. Also when it replicates thats how our hair, nails, and etc. grows. I also learned that the DNA is in the nucleus so that it can change into mRNA which sends messages to the ribosomes because it can't leave the nucleus. I love this topic because once you learn the basics of DNA everything else falls into place. It can be applied to outside of biology when your doing blood work and etc.

    This is really good you gave a lot information this helped me so much that I understand like the back of my hand. This does not need no improvement at all i'm proud of this blog this is the best one i've see yet . you don't need to add anything this is just so perfect well done boo. your reflection is amazing.

Anaerobic Energy Production - MORGAN BANKS

Image
ANAEROBIC ENERGY PRODUCTION  Anaerobic Energy Production is one form of Cellular Respiration  This form requiers no oxygen  Is used for a fast burst of energy Occurs mostly in prokaryotes cells  Fermentation 1- lactic acid (makes muscles sore)  2- Alocholic REFLECTION - Anaerobic Production has no oxygen, therefore many of the things we do, do not involve anaerobic production! It involves the aerobic energy production. This is not only a good review for you but for me as well on how to justify the two.  http://slideplayer.com/slide/9078035/ MORE INFO: http://www.diffen.com/difference/Aerobic_Respiration_vs_Anaerobic_Respiration VIDEO/QUIZ:  http://study.com/academy/lesson/anaerobic-exercise-definition-benefits-examples.html

Genetic Variation: Mutations

Image
What is a mutation? A mutation is any change in the DNA sequence.  There are three types of mutations: * addition: One or more nucleotide base pairs are inserted into a DNA sequence (also called frameshift mutation)  *deletion: The removal of one or more nucleotides in a DNA sequence (also called frameshift mutation) *substitution: A mutation that exchanges one or more bases for another (also called point mutation) How do they occur & why? Mutations for randomly, but different mutations occur different ways.  Most of the time a mutation comes from radiation (so like the sun, X-rays, tanning salons, etc). Some mutations can be genetic though, like autism. Autism is caused when theres an extra chromosome. Another common mutation would be cancer. Cancer occurs when cells uncontrollably grow, and don't die.  Can it be prevented?  Unfortunately, mutations are random. The best way to prevent them is to protect yoursel...
