Question
Please answer the following genetics / agronomy questions: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.
21. 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) T-DNA insertion approach is a knock-out mechanism in Arabidopsis that disrupts the gene of interest and the gene can no longer be transcribed into a functional mRNA. As such, this is an approach which works based on post-transcriptional regulation of gene expression. c) In overexpression approach, we can only increase expression of a gene through moficiation in its transcriptional regulation whereas in gene-silencing approach we can create modification in both transcriptional level and post-transcriptional level. d) Overexpression is a typical example of post-transcriptional control of overexpressing of a gene e) CRISPR-Cas approach is a system that works based on the concept of post-transcriptional modification of gene expression which degrades ribosomal RNA. f) a and c both are correct. g) a and e both are correct

Explanation / Answer
20) c is a answer
Talen technology is a considered as a forward genetic approach because it creates a new variation because it creates a new technologies ,new varieties and wide variety of genetic variations
