Protein Synthesis

What happens during the elongation phase of translation?

• Amino acids are added one by one to the growing polypeptide chain.

• The ribosome assembles the mRNA strand.

• tRNA molecules are released from the ribosome.

• The polypeptide chain is folded into its functional shape.

Where does Translation occur?

• Nucleus

• Mitochondria

• Ribosomes

• Endoplasmic Reticulum

What is the function of rRNA?

• rRNA is a component of ribosomes and plays a crucial role in protein synthesis.

• rRNA helps in the replication of DNA.

• rRNA is involved in the transport of amino acids to the ribosome.

• rRNA acts as a catalyst in metabolic reactions.

What are the building blocks of proteins?

• Nucleotides

• Fatty acids

• Amino acids

• Monosaccharides

What is the role of ribosomes in protein synthesis?

• Ribosomes are the sites where translation occurs and proteins are synthesized.

• Ribosomes are responsible for DNA replication.

• Ribosomes transport amino acids to the nucleus.

• Ribosomes are involved in the breakdown of proteins.

What is the significance of the start codon?

• It signals the end of translation and codes for the amino acid tryptophan.

• It signals the beginning of translation and codes for the amino acid methionine.

• It is involved in DNA replication and codes for the amino acid serine.

• It is a regulatory sequence that controls gene expression.

What is the process of copying DNA into RNA called?

• Transcription

• Translation

• Replication

• Translocation

What is the role of mRNA in protein synthesis?

• mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

• mRNA helps in the replication of DNA.

• mRNA is responsible for the folding of proteins.

• mRNA transports amino acids to the ribosome.

What is a mutation?

• A change in the DNA sequence that can affect protein synthesis and function.

• A type of cell division that produces identical cells.

• An error in the RNA transcription process.

• A process that leads to the formation of new species.

What is the function of tRNA?

• A small section of RNA that transports amino acids to the ribosome for synthesis into proteins.

• A type of RNA that carries genetic information from DNA to the ribosome.

• A molecule that catalyzes the formation of peptide bonds between amino acids.

• A form of RNA that helps in the replication of DNA.
