Question
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.
