Test 2-2: Fall 2024 Mock ACP

Front

What is the process of transcription in DNA?

Back

Transcription is the process of copying a sequence of DNA to RNA.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where it is translated into a protein.

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 significance of the 3' and 5' ends of a DNA strand?

Back

The 3' and 5' ends indicate the directionality of the DNA strand, which is crucial for processes like replication and transcription.

Front

What is a mutation in DNA?

Back

A mutation is a change in the nucleotide sequence of DNA, which can affect protein synthesis.

Front

What is the difference between replication and transcription?

Back

Replication is the process of copying the entire DNA molecule, while transcription is the process of copying a specific gene into RNA.

Front

What is the function 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 genetic code?

Back

The genetic code is the set of rules by which information encoded in mRNA is translated into proteins, consisting of codons.

Front

What is the role 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 deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.
