Honors Protein Synthesis Test Review

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA. It occurs in the nucleus of the cell.

Front

What is translation?

Back

Translation is the process of converting the sequence of a messenger RNA (mRNA) into a sequence of amino acids during protein synthesis.

Front

What is the start codon in RNA?

Back

The start codon is AUG, which codes for the amino acid Methionine.

Front

What is the role of DNA in protein synthesis?

Back

DNA serves as the template for the production of RNA, which is then translated into proteins.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of nucleic acids (DNA and RNA) and consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

How many amino acids are coded by a sequence of 12 nucleotides?

Back

A sequence of 12 nucleotides codes for 4 amino acids, as each amino acid is coded by a sequence of 3 nucleotides.

Front

What is a codon?

Back

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

Front

What is the function 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 significance of the stop codon?

Back

A stop codon signals the end of protein synthesis, indicating that the ribosome should release the newly formed polypeptide chain.
