3.4.7 Invatigatijg Diversity Flashcards
(3 cards)
1
Q
How can genetic diversity be measured
A
Comparing base sequence of DNA and mRNA
Comparing amino acid sequence of a specific protein
Freq of measurable/observable characteristics
2
Q
How can this comparison of DNA and mRNA indicate relationships between species
A
More differences in the sequences means more distantly related
As mutations build up over time they cause changes in amino acid sequence
3
Q
How have methods of investigating diversity changed over time
A
Was characteristics
Now gene technologies which directly show us DNA sequences
