Mutation: Addition

Mutation: Addition 

Main Ideas:

-An extra nucleotide is added to the strand of DNA
-Everything after the addition is changed (the codons and the amino acids)

Reflection with info:

During our time in class I learned that a mutation is any change in the DNA sequence. It could be caused by a spontaneous mistake (which I found kind of surprising) or a environmental factor that effected it. For example a environmental factor that could affect the DNA sequence is radiation. One mutation is addition which is the addition of one or more extra nucleotide base pairs that get added to the DNA sequence. This mutation is considered a frameshift mutation. When an extra nucleotide base pair is added it affects the codons and the amino acids. Overall I thought learning the mutations was pretty easy because it was almost self explanatory. One way you could use this out of our biology class is if you become an oncologist (a doctor who studies cancer and the prevention or other of it) because they need to know what causes the cancer and what went wrong with the DNA sequence involved.
