Protein Synthesis DOL

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.

Front

What is the process of transcription?

Back

Transcription is the process by which the genetic information in DNA is copied into mRNA.

Front

What is the role of tRNA in translation?

Back

tRNA (transfer RNA) brings the appropriate amino acids to the ribosome during translation, matching them to the codons on the mRNA.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides on mRNA that corresponds to a specific amino acid.

Front

What amino acid is represented by the codon UUA?

Back

Leucine.

Front

What is the process of translation?

Back

Translation is the process by which the sequence of nucleotides in mRNA is used to assemble a chain of amino acids to form a protein.

Front

What is the significance of the ribosome in protein synthesis?

Back

The ribosome is the cellular machinery that facilitates the translation of mRNA into a polypeptide chain (protein) by bringing together mRNA and tRNA.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of synthesizing mRNA from DNA, while translation is the process of synthesizing proteins from mRNA.

Front

What is the start codon and its significance?

Back

The start codon (AUG) signals the beginning of translation and codes for the amino acid methionine.

Front

What are the three main stages of translation?

Back

The three main stages of translation are initiation, elongation, and termination.
