Investigating Diversity Flashcards
1
Q
What can genome sequencing do?
A
Determine the order of DNA and bases in an organisms genome.
2
Q
When would genome sequencing typically be used?
A
When studying/comparing extinct species.
3
Q
Suggest 4 ways that genetic diversity can be studied by comparing.
A
- the frequency of measurable or observable characteristics
- the base sequence of DNA
- the base sequence of mRNA
- the amino acid sequence of the proteins encoded by DNA
and mRNA.
4
Q
What do 2 similar gene sequences suggest?
A
That the organisms are more closely related.
5
Q
Why do species that have been around for longer have greater genomes?
A
They have had time to accumulate different amino acid sequences, mutations, changes to DNA and RNA.
