Genetic Code and Gene Expression Quiz

What is the relationship between the proteome and the genome?

• The proteome is smaller than the genome

• The proteome is larger than the genome

• The proteome is the same size as the genome

• The proteome is unrelated to the genome

What are the building blocks of proteins?

• Nucleotides

• Amino acids

• Sugars

• Fatty acids

What is the main purpose of the transcription process?

• To replicate DNA

• To synthesize proteins

• To convert DNA into RNA

• To break down sugars

The DNA triplet code is said to be redundant. What does this mean?

• Each codon codes for only one amino acid.

• Multiple codons can code for the same amino acid.

• The triplet code is found in nearly all species.

• The genetic code has more codons (64) than necessary to code for the 20 amino acids.

What is the role of RNA polymerase in transcription?

• It synthesizes DNA from RNA.

• It binds to the promoter region of DNA.

• It terminates the transcription process.

• It translates RNA into proteins.

What is the role of the complementary strand in transcription?

• It serves as a template for RNA synthesis.

• It binds to the promoter.

• It is not directly involved in transcription.

• It terminates transcription.

What is the complementary RNA sequence for the DNA sequence 'TAC' in the diagram?

• ATG

• AUG

• UAC

• GUA

Which nucleotide is not found in RNA?

• Adenine

• Thymine

• Cytosine

• Uracil

In which direction does RNA polymerase synthesize the new strand of RNA?

• 5' to 3'

• 3' to 5'

• 2' to 4'

• 4' to 2'

In eukaryotic cells, where is the DNA located for transcription?

• Cytoplasm

• Nucleus

• Ribosome

• Cell membrane
