Protein Synthesis Practice

Front

What is protein synthesis?

Back

The process by which cells generate new proteins, involving transcription of DNA to mRNA and translation of mRNA to amino acids.

Front

What is transcription?

Back

The process of copying a segment of DNA into RNA, specifically mRNA, which occurs in the nucleus.

Front

What is translation?

Back

The process of decoding mRNA to synthesize proteins, which occurs at the ribosome in the cytoplasm.

Front

What is the role of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome for protein synthesis.

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

How many nucleotides are in a codon?

Back

Three nucleotides make up a codon, which codes for a specific amino acid.

Front

What is a codon?

Back

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

Front

What is the start codon?

Back

The start codon is AUG, which signals the beginning of translation and codes for the amino acid methionine.

Front

What is an amino acid?

Back

Amino acids are the building blocks of proteins, linked together by peptide bonds during translation.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.
