Protein Synthesis Review

Front

What enzyme is responsible for making mRNA from DNA?

Back

RNA polymerase is the enzyme that synthesizes mRNA from a DNA template during transcription.

Front

What are proteins made of?

Back

Proteins are made of amino acids, which are linked together by peptide bonds.

Front

What happens during translation?

Back

During translation, mRNA matches up with tRNA to form a protein, with tRNA bringing the appropriate amino acids.

Front

Which molecule contains codons?

Back

The molecule that contains codons is mRNA (messenger RNA), which is read during translation.

Front

What base in RNA replaces Thymine?

Back

In RNA, uracil replaces thymine, pairing with adenine during transcription.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) carries amino acids to the ribosome and matches them to the codons on the mRNA during translation.

Front

What is the process of transcription?

Back

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

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific 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 difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil instead of thymine.
