Transcription

What is the function of tRNA?

• tRNA transports amino acids to the ribosome during protein synthesis.

• tRNA synthesizes proteins from amino acids.

• tRNA carries genetic information from DNA to the ribosome.

• tRNA helps in the replication of DNA.

What process is used to make mRNA from the DNA in the nucleus?

• Transcription

• Translation

• Replication

• Translocation

Which statement is incorrect regarding RNA?

• RNA can ONLY be found inside the nucleus.

• RNA is involved in protein synthesis.

• RNA can be found in the cytoplasm.

• RNA is a type of nucleic acid.

What is the significance of uracil in RNA?

• Uracil replaces thymine in RNA and pairs with adenine during transcription.

• Uracil is a component of DNA that stabilizes its structure.

• Uracil is involved in protein synthesis as a structural component.

• Uracil acts as a catalyst in RNA replication.

What is the function of rRNA?

• rRNA is a structural component of ribosomes, which are the sites of protein synthesis.

• rRNA helps in the transport of amino acids to the ribosomes.

• rRNA is involved in the replication of DNA.

• rRNA acts as a catalyst in metabolic reactions.

What happens during the process of transcription?

• The DNA double helix unwinds, and RNA polymerase synthesizes a complementary RNA strand.

• The RNA double helix unwinds, and DNA polymerase synthesizes a complementary DNA strand.

• The ribosome assembles amino acids into proteins based on mRNA sequences.

• The DNA is replicated to form two identical DNA strands.

What is the blueprint for the production of RNA within a cell?

• RNA

• DNA

• Proteins

• Lipids

What is the result of the transcription of the DNA sequence GAT?

• CUA

• GUA

• AUC

• CUG

What is the role of RNA in the cell?

• RNA serves as a messenger carrying instructions from DNA for controlling the synthesis of proteins.

• RNA is responsible for storing genetic information.

• RNA helps in the replication of DNA.

• RNA acts as a structural component of the cell membrane.

What is the difference between DNA and RNA?

• DNA is single-stranded and contains uracil, while RNA is double-stranded and contains thymine.

• DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

• DNA and RNA are identical in structure and function.

• DNA is found in the nucleus only, while RNA is found in the cytoplasm only.
