Molecular Basis of Inheritance question

2023 · Q38

NEETBiologyMolecular Basis of InheritanceMCQ+4 / −1

Given below are two statements :

Statement I : The process of copying genetic information from one strand of the DNA into RNA is termed as transcription.

Statement II : A transcription unit in DNA is defined primarily by the three regions in the DNA i.e., a promotor, the structural gene and a terminator.

In the light of the above statements, choose the correct answer from the options given below :

  1. A
    Statement I is true but Statement II is false
  2. B
    Statement I is false but Statement II is true
  3. C
    Both Statement I and Statement II are true
  4. D
    Both Statement I and Statement II are false

Correct answer: C

Option C : Both Statement I and Statement II are true

Explanation :

Statement I is correct. Transcription is the process of copying genetic information from one strand of the DNA into RNA. The resulting RNA molecule is complementary to the DNA strand from which it was transcribed.

Statement II is also correct. A transcription unit in DNA is indeed defined by three main regions: the promoter, the structural gene, and a terminator.

  1. 1. The promoter is a DNA sequence that defines where transcription of a gene by RNA polymerase begins.
  2. 2. The structural gene contains the actual genetic information that is being transcribed.
  3. 3. The terminator is a sequence of nucleotides that signals the end of transcription.

So, both the statements are true.
