Protein Synthesis

Front

What is protein synthesis?

Back

Protein synthesis is the process by which cells generate new proteins, involving two main stages: transcription and translation.

Front

What is the role of mRNA in protein synthesis?

Back

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

Front

What is the function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) transports specific amino acids to the ribosome during protein synthesis, matching them to the corresponding mRNA codons.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid or a stop signal during protein synthesis.

Front

What amino acid is represented by the mRNA codon UUC?

Back

Phenylalanine.

Front

What is a polypeptide?

Back

A polypeptide is a chain of amino acids linked together by peptide bonds, which folds into a functional protein.

Front

What is transcription in protein synthesis?

Back

Transcription is the process of copying a segment of DNA into mRNA, which occurs in the nucleus.

Front

What is translation in protein synthesis?

Back

Translation is the process where ribosomes synthesize proteins by decoding the mRNA sequence into a chain of amino acids.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, facilitating the assembly of amino acids into proteins.

Front

What is the difference between DNA and RNA?

Back

DNA contains the genetic blueprint for an organism, while RNA is involved in protein synthesis and is single-stranded.
