Invesitigating Diversity

Question 1

What are the methods of investigating diversity

Answer 1

Observable characteristics
DNA base sequence
mRNA base sequence
Amino acid sequence of proteins

Question 2

What is the observable characteristic method and it’s issues

Answer 2

Similarities and differences of phenotype used as measure if assuming characteristics are coded by genes

However :
Characteristics may be changed by environment
Many traits caused by more than 1 gene

Question 3

What is DNA base sequence method

Answer 3

Fluorescent dye attached to each base, analysis by computer programme. similarities between organisms base sequence help discover evolutionary relationships

Question 4

mRNA base sequence method

Answer 4

Can be used to see DNA sequence using complementary mRNA bases

Question 5

Amino Acid sequence of proteins method

Answer 5

Scientists count the number of similarities and differences and see which species share similar sequences
