During which process is mrna synthesized from a dna template with the aid of rna polymerase?
a. transcription
b. translation
c. translocation
d. transportation

The correct answer is A) Transcription.

Transcription is a genetic process by which the genetic information from a template of DNA (deoxyribonucleic acid) is copied into mRNA (messenger RNA). It is mediated by the enzyme called RNA polymerase. It occurs in nucleus of eukaryotes and cytoplasm of prokaryotes.

mRNA thus produced in this process, contains codons (a sequence of three nucleotides coding for a particular amino acid) that help in the synthesis of proteins through a process called translation.

Thus, option A) Transcription is the right answer.

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes
