26.4 Genome Flashcards
1
Q
how do scientists use DNA to track evolutionary lineages
A
different genes evolve at different rates allowing them to represent long and short periods of time
2
Q
long periods of time use what type of DNA
A
rRNA that evolves slowly
-useful in investigating diver genes 100s of years ago
3
Q
short periods of time use what type of DNA
A
mtDNA
evolves rapidly and explores recent events
