The process of copying the genetic information from one strand of DNA into RNA is termed as transcription. The principle of complementarity of bases governs the process of transcription, also except that uracil comes in place of thymine.Study the complete transcription unit given below and answer the following questions:
Identify coding strand and template strand of DNA in the transcription unit.
Show Hint
RNA polymerase synthesizes the RNA strand using the template DNA strand, creating a complementary sequence that mirrors the coding strand (with uracil replacing thymine).
The coding strand is the strand of DNA that has the same sequence as the mRNA (except for the substitution of uracil for thymine). In the diagram, it is represented as the strand labeled as C.
- The template strand is the strand of DNA that serves as the template for RNA synthesis. It is complementary to the mRNA sequence and in the diagram, it is represented as the strand labeled as D.
