Need help understanding DNA replication and link to translation & transcriptionWatch
I'm doing A-level biology, please help !
Transcription and translation on the other hand are used in protein production, not in DNA production. Transcription is the process of RNA polymerase producing complementary mRNA from one of the DNA strands. This mRNA leaves the nucleus via nuclear pores, and goes to a ribosome either in the cytoplasm or on the rough endoplasmic reticulum. The ribosome translates the mRNA by matching the codons with complementary anticodons on tRNA, which carry amino acids. The ribosome reads along the mRNA, binds the correct tRNA, and catalyses peptide bonds forming between the amino acids, creating a polypeptide chain.
Basically, DNA replication is unrelated to the other two and produces DNA, while transcription and translation produce proteins/polypeptides.
