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.

alternative D.

Explanation: For the DNA to have the double strand structure, it is necessary to copy the sequence of the existing DNA strand in a complementary sequence of nucleotides, forming hydrogen bonds between them. The mRNA also uses this strategy when reading the DNA strand during the transcription, in order for the translation to begin.

d. They both copy genetic code by forming a complementary sequence of nucleotides with an existing strand of DNA.

Explanation:

it takes hundreds of years to become stable.

if you have another question lmk.

the answer is: reproductively

i think i spelled it wrong lol

anyways hope i
