protein synthesis

What is the difference between transcription and translation?

• Transcription is the process of synthesizing proteins from DNA, while translation is the process of synthesizing mRNA from proteins.

• Transcription is the process of synthesizing mRNA from DNA, while translation is the process of synthesizing proteins from mRNA.

• Transcription and translation are the same processes that occur simultaneously in the cell.

• Transcription is the process of synthesizing DNA from RNA, while translation is the process of synthesizing mRNA from DNA.

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 difference between DNA and RNA?

• DNA is single-stranded and contains ribose sugar.

• DNA is double-stranded and contains deoxyribose sugar.

• RNA is double-stranded and contains deoxyribose sugar.

• RNA is single-stranded and contains deoxyribose sugar.

What is the role of ribosomes in protein synthesis?

• Ribosomes are the site of translation where 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 are the building blocks of proteins?

• Nucleotides

• Fatty acids

• Amino acids

• Monosaccharides

What is the process to go from DNA to mRNA?

• Translation

• Replication

• Transcription

• Mutation

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 carries amino acids to the ribosome.

• A structure that protects the DNA from damage.

Where does translation occur in the cell?

• Nucleus

• Mitochondria

• Ribosome

• Golgi apparatus

What is the role of introns and exons in genes?

• Introns are coding regions that are expressed, while exons are non-coding regions that are removed during mRNA processing.

• Introns are non-coding regions that are expressed, while exons are coding regions that are removed during mRNA processing.

• Introns are non-coding regions that are removed during mRNA processing, while exons are coding regions that are expressed.

• Introns and exons both play a role in protein synthesis without any removal during mRNA processing.

What is a gene?

• The information for making a polypeptide.

• A type of protein that catalyzes reactions.

• A segment of DNA that codes for a trait.

• A molecule that carries oxygen in the blood.
