DNA
What is the purpose of Mitosis
Repair and grow new cells
What is the purpose of Meiosis
to produce gamete or sexual reproduction cells
How does a mutation impact the organism?
A mutation results in a new amino acid or protein being produced which changes the trait in an organism
How many pairs of chromosomes does a human cell have?
23 pairs of chromosomes
What are the base pairs in DNA?
A-T C-G
How can you tell if organisms are closely related using their DNA strands?
By comparing the DNA sequences of different organisms, they can assess the degree of similarity between the genetic codes. The more similar the DNA sequences are, the more closely related the organisms are believed to be.

Describe what a DNA strand would like like after replication.
after replication two DNA strands look identical each made up of one strand from the original DNA and one new strand that was paired
Describe a mutation and how you can recognize a mutation on a DNA strand
A mutation is a change in the DNA code. It can happen by mistake or from outside factors. Mutations can be good, bad, or neutral for an organism. Scientists find mutations by comparing the changed DNA to the original to see what's different.
