It is responsible for passing on the heritable information from parent to offspring Replication 2. It is responsible for protein synthesis Transcription Translation V. Replication. B. Two strands of DNA break their H bonds and unwind to expose their bases. C. Unattached nucleotides pair with exposed bases. The first step in making a protein is to first make some RNA, specifically mRNA .
Transcription occurs in the nucleus.
Complementary nucleotides are added to one of the the DNA strands. RNA polymerase continues along the DNA gene adding the appropriate nucleotides until it hits a stop signal. The mRNA message now needs to be translated so that a protein can be made. The mRNA has a three nucleotide genetic code . A G valine alanine aspartate glycine G 3.
