Question
18. Which statement is correct?
a) 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 transcriptional regulation of gene expression.
b) Talen technology is considered as forward genetic approach because it creates a new variation.
c) In forward genetic approach, we determine the function of gene by analyzing the phenotypic effects of altered DNA sequences.
d) 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.
Explanation / Answer
Answer is option A.
Explanation:
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. This is a best approach which works based on transcriptional regulation of gene expression.
