Protein Synthesis

What is the purpose of anti-codons?

• To ensure the correct amino acid is dropped off.

• To initiate the process of transcription.

• To bind to ribosomes during protein synthesis.

• To transport mRNA from the nucleus to the cytoplasm.

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 are the building blocks of proteins?

• Nucleotides

• Fatty acids

• Amino acids

• Monosaccharides

What is the role of tRNA in protein synthesis?

• To transport amino acids to the ribosome and match them to the corresponding codon on mRNA.

• To synthesize mRNA from DNA during transcription.

• To form the ribosomal subunits that facilitate protein synthesis.

• To provide energy for the translation process.

What is the significance of the start codon?

• It signals the beginning of translation.

• It marks the end of transcription.

• It initiates DNA replication.

• It codes for a stop signal.

Where does transcription occur?

• Cytoplasm

• Nucleus

• Ribosome

• Mitochondria

What is the genetic code?

• The sequence of nucleotides in DNA that determines genetic traits.

• The set of rules by which information encoded in mRNA is translated into proteins.

• A type of RNA that carries amino acids to the ribosome.

• The process by which DNA is replicated before cell division.

What is the function of ribosomes in protein synthesis?

• To facilitate the translation of mRNA into a polypeptide chain.

• To transcribe DNA into RNA.

• To modify proteins after synthesis.

• To transport amino acids to the ribosome.

Where is the anticodon located on a tRNA molecule?

• At the top of the molecule.

• In the middle of the molecule.

• At the bottom of the molecule.

• On the side of the molecule.

What process is occurring when mRNA is translated into a protein?

• Transcription

• Replication

• Translation

• Translocation
