The strand of DNA acting as template for mRNA transcription is

(a) Coding strand (b) Noncoding strand (c) Sense strand (d) Antisense strand. The correct answer is

Q. Write polarity of template strand and coding strand. Write three regions of transcription unit of DNA.

Q.

Differentiate between the followings

(a) Repetitive DNA and satellite DNA

(b) mRNA and t RNA

(c) Template strand and coding strand

Q. Assertion :Template or antisense strand, having 3 \\ 5 polarity takes part in transcription. Reason: Non-template or sense strand, having 5 \\ 3 polarity, does not take part in transcription.

Q. How many of the following statements are correct?

A. Coding strand is also called a template strand which gets transcribed to RNA.

B. Template strand is considered as a non-coding strand which gets transcribed to RNA.

C. Coding strand of DNA (sense strand) has the same sequences as transcribed RNA, except for having thymine in place of RNA’s uracil.

D. The template strand of DNA has the same sequences as transcribed RNA.

E. Coding strand (sense strand) has the same sequences as transcribed RNA, except for having uracil in place of RNA’s thymine.

Q. Differentiate between a template strand and coding strand of DNA.
