Gene Function Quiz

At what two levels can we look at gene function?

• Cellular structure and organism's behavior

• Molecular function and organism's trait

• Genetic code and protein synthesis

• DNA replication and cell division

How are the two levels of gene function connected?

• The organism's trait determines the molecular function

• The molecular function affects the structure and function of cells to determine the trait

• The genetic code directly influences the organism's behavior

• The protein product is unrelated to the organism's trait

What is produced during the transcription process?

• DNA copy of a gene

• Protein sequence

• RNA copy of a gene

• Amino acid chain

What does messenger RNA (mRNA) specify?

• The sequence of nucleotides in DNA

• The amino acid sequence of a polypeptide

• The structure of a ribosome

• The function of a protein

What is the process of synthesizing a specific polypeptide on a ribosome using the mRNA template called?

• Transcription

• Replication

• Translation

• Mutation

What is the correct sequence of the central dogma of molecular biology?

• RNA → DNA → Protein

• DNA → Protein → RNA

• DNA → RNA → Protein

• Protein → RNA → DNA

What is the intervening step in eukaryotes where pre-mRNA is processed into active mRNA called?

• DNA replication

• RNA modification

• Protein synthesis

• Transcription

In eukaryotes, where does transcription occur?

• Cytoplasm

• Ribosome

• Nucleus

• Mitochondria

In bacteria, where do transcription and translation occur?

• Nucleus

• Cytoplasm

• Ribosome

• Endoplasmic reticulum

What is the correct sequence of the central dogma in molecular biology?

• Protein → mRNA → DNA → pre mRNA

• DNA → mRNA → pre mRNA → Protein

• DNA → pre mRNA → mRNA → Protein

• mRNA → DNA → Protein → pre mRNA
