DNA & Protein Synthesis Warmup

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the process of transcription?

Back

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

Front

Where does translation occur in the cell?

Back

Translation occurs in the ribosome.

Front

What is a codon?

Back

A codon is a three-nucleotide sequence in mRNA that codes for a specific amino acid.

Front

What is the complementary DNA sequence for the mRNA sequence CUG?

Back

The complementary DNA sequence is GAC.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, synthesizing proteins by linking amino acids together.

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 the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during translation, matching them to the codons in mRNA.

Front

What is the start codon for protein synthesis?

Back

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

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein synthesis.
