23 Protein Synthesis Review

Front

What is the function of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, linked together in a specific sequence to form a protein.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating mRNA into a polypeptide chain.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid.

Front

How many nucleotides are needed to code for one amino acid?

Back

Three nucleotides are needed to code for one amino acid.

Front

What is the process of transcription?

Back

Transcription is the process of copying a segment of DNA into mRNA.

Front

What is the process of translation?

Back

Translation is the process where ribosomes read mRNA and assemble amino acids into a polypeptide chain.

Front

What is tRNA and its function?

Back

tRNA (transfer RNA) delivers amino acids to the ribosome during protein synthesis.

Front

What is the significance of the start codon?

Back

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

Front

What is the significance of the stop codon?

Back

Stop codons signal the end of protein synthesis, causing the ribosome to release the completed polypeptide.
