Question

17. The segment of the master strand of DNA involved in transcription is called:

(a) Sense strand
(b) Cistron
(c) Recon
(d) Muton​

Answer 1

Explanation:

ciston

have a great day ahead dear

Answer 2

The correct answer is option b. Cistron.

• Cistron is the segment of DNA involved in the transcription that having information for the synthesis of a particular RNA or protein.
• These are the functional subunits of genes.
• Consists of both coding and regulatory sequences.
• Polycistronic mRNA are found in prokaryotes while Monocistronic mRNA are present in eukaryotes.
• In polycistronic, a single promoter directs the synthesis of one mRNA that can be translated to more than one polypeptide whereas, in the case of monocistronic, one promoter directs the synthesis of one mRNA that usually translates to only one protein.
• Recon is the smallest unit of DNA capable of undergoing crossing over and recombination.
• Muton is the smallest unit of DNA that can undergo mutation.
