Which of the following types of molecules could bind to an ncRNA due to base pairing?
- DNA
- RNA
- protein
- small molecule
- both a and b
Introduction:
Base pairs are two identical nitrogen molecules bound by hydrogen bonds in molecular biology. Base pairs are present in double-stranded DNA and RNA, where the two strands are bound by the bonds between them, making double-stranded structures possible.
Answer to Problem 1TY
The correct answer is option (e) both a and b.
Explanation of Solution
Explanation/justification for the correct answer:
Option (e) both a and b. ncRNA can bind to both DNA and RNA due to base pairing and can cause transcription, translation, and DNA replication. So, the correct answer is option (e).
Explanation for incorrect answer:
Option (a) DNA. ncRNA binds to DNA with base pairing. ncRNA also binds to RNA with base pairing. So, this is an incorrect option.
Option (b) RNA. ncRNA binds to both DNA and RNA with base pairing. So, this is an incorrect answer.
Option (c) protein. ncRNA binds to proteins but not with base pairing. It binds with proteins with the loops formed in it. Therefore, this is an incorrect option.
Option (d) small molecule. ncRNA binds to small molecules with loops formed like tRNA. The attachment of small molecules are not with base pairing. Therefore, this answer is incorrect.
