• Replication

• Mutation

Where does transcription occur in eukaryotic cells?

• In the cytoplasm

• On the ribosome

• In the nucleus

• Inside mitochondria

Which molecule carries the genetic code from DNA to the ribosome?

• tRNA

• mRNA

• rRNA

• DNA polymerase

What is the role of tRNA in protein synthesis?

• It replicates DNA.

• It carries amino acids to the ribosome.

• It forms the ribosome structure.

• It transcribes DNA into RNA.

Which process converts mRNA into a sequence of amino acids?

• Transcription

• Translation

• Replication

• Mutation

What are the building blocks of proteins?

• Nucleotides

• Sugars

Which part of the cell is the site of protein synthesis?

• Nucleus

• Mitochondria

• Ribosome

• Endoplasmic reticulum

What is the significance of the genetic code during protein synthesis?

• It determines the sequence of sugars in DNA.

• It determines the sequence of amino acids in a protein.

• It replicates DNA molecules.

• It modifies proteins after synthesis.

How many nucleotides make up a codon?

• 1

• 2

• 3

• 4

What is the role of ribosomal RNA (rRNA) in protein synthesis?

• It carries amino acids to the ribosome.

• It carries the genetic code from DNA to the ribosome.

• It makes up the major part of the ribosome.

• It assists in the replication of DNA.
