Question

Silencing of a gene could be achieved through the use of:
a. short interfering RNA (RNAi)
b. antisense RNA
c. by both
d. none of the above

Chapter 12. Biotechnology and its Apllications

Answer 1

Answer is option c "by both"

Explanation:

• RNAi happens in every single eukaryotic cell as a technique for cell guard. This technique includes the silencing of a particular mRNA because of a corresponding dsRNA atom that ties to and prevents the interpretation of the mRNA.
• The source of this correlative RNA could be from disease by infections having RNA genomes or versatile hereditary components (transposons) that imitate by means of an RNA intermediate
• So,the right answer is option c " by both"

Answer 2

Silencing of gene could achieved through the use of short interfering RNA and antisense RNA.

Explanation:

Gene silencing means regulation of the expression of genes in a cell to prevent the expression of certain genes.

This occurs during transcription and translation.

The silencing genes reduces the expression of genes up to 70% but are unable to eliminate it completely.
