Protein Synthesis Flashcards
1
Q
Describe the Translation stage of Protein Synthesis.
A
(mRNA arrives at) the ribosome,
mRNA has codons which are a template for the protein,
The ribosome moves along the mRNA strand,
tRNA brings amino acids to the ribosome,
The anticodon (on the tRNA) binds with the codon (on the mRNA),
An amino acid chain is produced.

Q
Describe the Transcription stage of Protein Synthesis.
A
RNA polymerase binds to a region of DNA in a gene.
The two DNA strands separate and the RNA polymerase moves along one of the strands of DNA.
It uses the DNA in the gene as a template to make the mRNA. The mRNA is formed with bases that are complementary to the gene.
The mRNA molecule then moves out of the nucleus, into the cytoplasm.
