Protein synthesis

Where does transcription occur in the cell?

• Cytoplasm

• Nucleus

• Mitochondria

• Ribosome

What is the role of ribosomes in protein synthesis?

• Ribosomes are the sites of translation where proteins are synthesized from mRNA.

• Ribosomes are responsible for DNA replication.

• Ribosomes transport amino acids to the nucleus.

• Ribosomes are involved in the breakdown of proteins.

In which cellular process is mRNA synthesized?

• Translation

• Replication

• Transcription

• Translocation

What is the function of tRNA in protein synthesis?

• tRNA transports amino acids to the ribosome during translation.

• tRNA synthesizes proteins from amino acids.

• tRNA acts as a catalyst in the formation of peptide bonds.

• tRNA carries genetic information from DNA to the ribosome.

What is the significance of the genetic code?

• It determines the color of an organism's eyes.

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

• It controls the speed of cellular metabolism.

• It dictates the shape of an organism's body.

What happens during the elongation phase of translation?

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

• The ribosome disassembles after protein synthesis is complete.

• mRNA is synthesized from a DNA template.

• The polypeptide chain is folded into its functional shape.

What are the building blocks of proteins?

• Nucleotides

• Fatty acids

• Amino acids

• Monosaccharides

What is a codon?

• A sequence of three nucleotides in mRNA that codes for a specific amino acid.

• A type of protein that helps in DNA replication.

• A molecule that transports amino acids to ribosomes.

• A structure that protects the DNA from damage.

What is the role of DNA in protein synthesis?

• DNA is responsible for energy production in cells.

• DNA contains the genetic instructions for synthesizing proteins.

• DNA helps in the digestion of food.

• DNA is involved in the transport of oxygen in the blood.

What is the process of synthesizing mRNA from DNA called?

• Translation

• Replication
