Causes of Mutation- MORGAN

CAUSES OF MUTATIONS ! 


A mutation is any change in DNA sequence


     CAUSES- A mistake in copying DNA, OR, by exposure to certain enviromental factors  

3 TYPES OF MUTATIONS

ADDITION: One or more nucleotide base pairs inserted into the DNA sequence
EX:   Oringinal DNA- THE CAT ATE THE RAT 
Mutated DNA- THE CGA TAT ETH ERA T

DELETION: Removal of one or more nucleotide in a DNA sequence 
EX:  Oringnal DNA- THE CAT ATE THE RAT 
Mutated DNA- THE CTA TAT ETH ETA 

SUBSTITUTION: Mutation that exchanges one or more bases for another result in a different amino-acid coden reading
EX:  Oringnal DNA - THE CAT ATE THE RAT 
Mutated DNA- THE CGT ATE THE RAT 

*REMEMBER*
Mutagen-Is any agent that results in a mutation

Somatic Effects - Cant pass to child. ONLY the individual. ( think body cells ) 

Genetic Effects- Can pass to child 

Reflection- I learned a little more then what i didnt know; Not all mutations will pass onto the offspring. Throughout my family the only person i know with a mutation would be my papaw, he is blind in his left eye. And my left eye is my bad eye; so my papaw has a mutation and i believe i do or will someday.

    There was a lot of useful information. It really helped me because I didn't understand this topic well before. The video quiz was also very helpful.

    I really liked how you had everything well structured meaning it was easy to read and just easy to follow along. I can also relate to your reflection because at first I really didn't know that a mutation couldn't be passed down to the offspring. You did an outstanding job with your facts but for mutagen an example of a mutagen or an example of a somatic effect would of helped better understand.

    This was very well rounded and organized. You could improve by using bullet points. Your reflection was very informative and shows you know the topic.

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...
