A gene (def) is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA). Since the vast majority of genes are transcribed into mRNA and mRNA is subsequently translated into polypeptides or proteins, most genes code for protein synthesis. gene (def) is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA).

Translation is the process of making peptide strands from primary transcript. There are a set of aminoacids which are carried to the site of translation by specific transfer RNAs for the process. Apart from this messenger RNAs and ribosomal RNAs also play significant roles in translation. Comparison: Transcription vs. Translation in DNA Precursor molecule â For transcription the DNA is the parental strand where as for translation it is the primary transcript (RNA). Functionâ Transcription produces an RNA molecule complementary to the DNA strand where as translation produces the peptide sequence which is complementary to the RNA (same as the DNA sequence).
