Question

Explain the concept of a mutation and how mutations can translate to loss or gain of function in an organism. Discuss how mutations can be part of the Darwinian theories of natural selection. What are frameshift mutations, and why are they so devastating? What are the two main categories of mutations that occur in humans? Name and define the two types.

Answer 1

Answer:

Mutation is when there is a change in the DNA of a living creature. Some mutations can render a creature inviable by removing its ability to achieve homeostasis, which others can bring a much needed trait to a creature. Some are just mildly annoying or don't really change anything for a creature.

Mutations introduce traits that can cause the individual to be selected/ or prevent from its selection from its environment, therefore contributing to evolution.

A frameshift mutation is a genetic mutation caused by a deletion or insertion in a DNA sequence that shifts the way the sequence is read.

The two main categores of mutations that occur in humans are: Point mutations and chromosomal mutations. Point mutations include frameshift mutations and substitution, while chromosomal mutations affect an entire chromosome.

This is more about knowing how to string the correct concepts together, don't know how to help you with that. I advise taking an English course, as that will greatly help you with most subjects.
