Protein Synthesis Quiz

What is the main function of DNA in the cell?

• Providing energy for cellular functions

• Storing the instructions for building proteins

• Breaking down food molecules

• Transporting oxygen throughout the body

A gene is best described as:

• A protein that controls cellular activities

• A sequence of DNA that contains instructions for making a protein

• A group of cells that perform the same function

• A section of RNA that carries amino acids

What are the building blocks of proteins?

• Nucleotides

• Ribosomes

• Amino acids

• Codons

Which process occurs first in protein synthesis?

• Translation

• Replication

• Transcription

• Mutation

Where does transcription take place in a eukaryotic cell?

• Ribosome

• Nucleus

• Cytoplasm

• Golgi apparatus

What is the role of mRNA in protein synthesis?

• It brings amino acids to the ribosome

• It serves as a template for making proteins

• It forms the structure of the ribosome

• It helps DNA replicate

What molecule is responsible for bringing amino acids to the ribosome?

• mRNA

• rRNA

• tRNA

• DNA

A codon is a sequence of how many nucleotides?

• 1

• 2

• 3

• 4

The 'start' codon that signals the beginning of translation codes for which amino acid?

• Glycine

• Methionine

• Serine

• Alanine

What happens at the ribosome during translation?

• DNA is copied into RNA

• The amino acid sequence is built based on the mRNA sequence

• Introns are removed from RNA

• Ribosomes synthesize DNA
