20. Which statement is correct?

a) Site-directed mutagenesis is considered as one of the reverse genetic approaches because intend to substitute specific amino acid and evaluate the phenotypic effect of the substitution.

b) In a knock-out mouse the gene is expressed into mRNA but a mechanism prevents the process that translates mRNA into protein.

c) Talen technology is considered as forward genetic approach because it creates a new variation.

d) In forward genetic approach, we determine the function of gene by analyzing the phenotypic effects of altered DNA sequences.

Explanation / Answer

d.

in reverse genetic approach, function of gene is determined by analyzing the phenotypic effects of altered gene sequences.

forward genetics is to determinegenetic basis responsible for phenotype.
