Protein Synthesis Vocabulary

Front

What is the role of the ribosome in protein synthesis?

Back

The ribosome is the cellular structure where translation occurs, synthesizing proteins by linking amino acids together based on the sequence of mRNA.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, which carries the genetic information to the ribosome.

Front

What is translation?

Back

Translation is the process where the ribosome reads the mRNA sequence and assembles amino acids into a polypeptide chain, forming a protein.

Front

Where does transcription occur in eukaryotic cells?

Back

Transcription occurs in the nucleus of eukaryotic cells.

Front

Where does translation occur in the cell?

Back

Translation occurs in the cytoplasm, specifically on ribosomes.

Front

What is mRNA?

Back

mRNA (messenger RNA) is a type of RNA that carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is tRNA?

Back

tRNA (transfer RNA) is a type of RNA that brings amino acids to the ribosome during translation, matching them to the mRNA codons.

Front

What is the function of amino acids in protein synthesis?

Back

Amino acids are the building blocks of proteins; they are linked together in a specific sequence to form a protein during translation.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides on mRNA that corresponds to a specific amino acid or a stop signal during protein synthesis.

Front

What is the start codon?

Back

The start codon is the first codon of mRNA that is recognized by the ribosome, typically AUG, which codes for the amino acid methionine.
