Question

Double-stranded regions of RNA:A) are less stable than double-stranded regions of DNA.B) can be observed in the laboratory, but probably have no biological relevance.C) can form between two self-complementary regions of the same single strand of RNA.D) do not occur.E) have the two strands arranged in parallel (unlike those of DNA, which are antiparallel).

Answer 1

Answer: C

Explanation: This happens because RNA becomes double stranded when two self complementary region of a single strand form a hairpin like structure...

Answer 2

Answer: Option C.

Can form between two complimentary regions of same single strand Rna

Explanation:

A double stranded RNA is RNA that have two complementary base pairing strands commonly found in cells of living organisms just like DNA. In double stranded RNA thymine is replacesd by uracil and it is the genetic constituent of some viruses. Double stranded RNA are capable of triggering RNA interference in eukaryotic organisms and interferon response in vertebrates.
