Protein synthesis video quiz

What structure within most human cells contains the genome?

• Cytoplasm

• Ribosome

• Nucleus

• Mitochondria

How is DNA packaged within a chromosome?

• It is a loose, uncoiled strand.

• It is tightly packaged around proteins called histones.

• It is contained within a lipid bilayer.

• It is directly exposed to the cytoplasm.

What is the process called where an enzyme moves along a DNA strand to create a messenger RNA (mRNA) strand?

• Translation

• Replication

• Transcription

• Mutation

What is the function of transfer RNA (tRNA) molecules during protein synthesis?

• They carry the genetic code from the nucleus to the cytoplasm.

• They form the structural components of ribosomes.

• They carry amino acids to the ribosome to build a protein chain.

• They unwind the DNA double helix during transcription.
