Question

In which of the following ways are DNA and mRNA similar?

a. They are both always kept in the nucleus to keep them safe from damage.
b. They are both double-stranded and must be unzipped during replication and transcription.
c. They both contain the entire genetic sequence of the original DNA from their parent cell.
d. They both copy genetic code by forming a complementary sequence of nucleotides with an existing strand of DNA.

Answer 1

The correct option is D.
Both the DNA and the mRNA are involved in the copying of genetic codes from an already existing DNA.
The DNA acts as the storage for the genetic information which are used in the process of protein synthesis. The information on the DNA is normally transcribed on to the mRNA, which will carry it to the ribosomes in the cytoplasm.
