MET-PRO-VAL-GLY-STOP

Front

What does each codon in mRNA specify?

Back

Amino acid

Front

What type of mutation is represented by the change from T-G-A-C-C-A to T-G-A-G-C-A?

Back

Substitution

Front

What is the correct sequence of protein synthesis?

Back

B. DNA serves as templates for mRNA, C. mRNA moves to ribosomes, A. tRNA brings amino acids to the ribosome, D. Polypeptides are formed on ribosomes.

Front

Define translation in the context of protein synthesis.

Back

Translation is the process by which ribosomes synthesize proteins using mRNA as a template.

Front

What role does tRNA play in translation?

Back

tRNA transports specific amino acids to the ribosome, matching them to the codons on the mRNA.

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 machinery that facilitate the assembly of amino acids into polypeptides.

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.
