Protein Synthesis Review

Front

What is a codon?

Back

A codon is a sequence of three nucleotide bases in mRNA that codes for a single amino acid.

Front

What does mRNA stand for?

Back

mRNA stands for messenger RNA, which carries genetic information from DNA to the ribosomes for protein synthesis.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating mRNA into amino acid sequences.

Front

What is the complementary mRNA sequence for the DNA strand AACTGAA?

Back

The complementary mRNA sequence is UUGACUU.

Front

What amino acid does the mRNA codon GCA code for?

Back

The mRNA codon GCA codes for the amino acid Alanine (Ala).

Front

What is the function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings amino acids to the ribosome and matches them to the codons in the mRNA.

Front

What is the difference between DNA and RNA?

Back

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

Front

What is an anticodon?

Back

An anticodon is a sequence of three nucleotides in tRNA that is complementary to a codon in mRNA.

Front

What is the process of transcription?

Back

Transcription is the process of copying a segment of DNA into mRNA.

Front

What is the process of translation?

Back

Translation is the process where ribosomes read mRNA and synthesize proteins by linking amino acids together.
