Which strand of DNA works as template strand in transcription?
1 5' - 3' polarity strand
2 3' - 5' polarity strand
3 Both (1) and (2)
4 None of these
Explanation:
The strand that has the polarity \(3^{\prime} \rightarrow 5^{\prime}\) acts as a template, and is also referred to as template strand

Read the Statements A and B. Choose the right one. Statement A : Synthesis of mRNA takes place in \(5^{\prime} \rightarrow 3^{\prime}\) direction. Statement B : Reading of mRNA is always in \(3^{\prime} \rightarrow 5^{\prime}\) direction.
1 Both the statements are wrong.
2 Statement A is wrong, Statement B is correct.
3 Statement B is wrong, Statement A is correct.
4 Both the statements A and B are correct.
Explanation:
The antisense strand of DNA which runs from 3'-5' direction act as a template for RNA synthesis by RNA polymerase. So, the RNA is synthesised in 5'-3' direction. During translation, the ribosomes attach to the \(5^{\prime}\) end of the m-RNA and transcribe till the \(3^{\prime}\) end. So, the reading of mRNA takes place in \(5^{\prime}-3^{\prime}\) direction..

Why both the strands of DNA are not copied during transcription?
1 Because RNA molecule with different sequences will be formed
2 Because RNA molecule with same sequences will be formed
3 Because protein molecule with different aminoacid sequence will be formed
4 Both 1 and 3
Explanation:
If both strands act as a template, they would code for RNA molecule with different sequences (Remember complementarity does not mean identical), and in turn, if they code for proteins, the sequence of amino acids in the proteins would be different.

Choose the correct pair.
1 Promoter - Binding site for RNA polymerase
2 Terminator - end of the transcription process
3 Both 1 and 2
4 Regulatory genes - code for any RNA or proteins genes
Explanation:
(1) Promoter - Binding site for RNA polymerase (2) Terminator - end of the transcription process, both are correct.
