Question

Which of the following occurs in the process of central dogma reverse?

(a) Conversion of a strand of mRNA to DNA

(b) Changes in the chromosomal karyotype

(c) Gene replication process

(d) Protein production process

This question was posed to me in final exam.

My doubt is from Structure of a Polynucleotide Chain topic in portion Molecular Basis of Inheritance of Biology – Class 12

Answer 1

The correct option is (a) Conversion of a strand of mRNA to DNA

The explanation: Central dogma is the process of conversion of DNA->mRNA->protein. On the contrary, central dogma reverse is the conversion of RNA->DNA. The formed DNA in the process of central dogma reverse or reverse transcription, can undergo the processes of transcription and translation after that.
