Why is the structure of a protein important for its function?

• The structure determines how the protein folds and interacts with other molecules.

• The structure determines the rate of transcription.

• The structure determines the amount of energy a cell can use.

• The structure determines the speed of DNA replication.

Which of the following molecules is directly responsible for assembling the amino acids into a protein chain during translation?

• DNA

• Ribosome

• tRNA

• mRNA

What process is being shown?

• Transcription

• DNA replication

• Translation

• Protein synthesis

Which part of DNA carries the genetic information that specifies a protein's amino acid sequence?

• Phosphate group

• Sugar backbone

• Nitrogenous base sequence

• Ribosomal RNA

What is the role of tRNA during translation?

• To transcribe the DNA into mRNA.

• To bring amino acids to the ribosome.

• To fold the protein into its three-dimensional shape.

• To form the peptide bonds between amino acids.

How is the sequence of amino acids in a protein determined?

• By the structure of the ribosome.

• By the sequence of nucleotides in mRNA.

• By the shape of the DNA molecule.

• By the folding of the protein.

The monomer of DNA is known as:

• Nucleolus

• Nucleic acids

• Nucleus

• Nucleotide
