Question

Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of___________________. siRNA plays many roles, but its most notable is in the RNA interference (RNAi) pathway, where it interferes with the expression of specific genes with complementary nucleotide sequence.

a. mobile RNA molecules
b. small nuclear RNA molecules
c. single-stranded RNA molecules
d. short messenger RNA molecules
e. double-stranded RNA molecules

Answer 1

e. double-stranded RNA molecules. siRNA is a class of double-stranded RNA molecules that interfere with the expression of specific genes. It plays a role in gene silencing and has potential therapeutic applications.

Step-by-step explanation:

Small interfering RNA (siRNA) is a class of double-stranded RNA molecules. It plays a significant role in the RNA interference (RNAi) pathway, where it interferes with the expression of specific genes by binding to their corresponding mRNA molecules and preventing protein synthesis. siRNA is involved in gene silencing and is being explored as a potential therapeutic tool in treating diseases.
