Transcription & Translation

What is the process of copying DNA called?

• Transcription

• Translation

• Replication

• Recombination

What is the structure of DNA?

• DNA is a single strand of nucleotides.

• DNA is a double helix composed of two strands of nucleotides.

• DNA is a triple helix made of amino acids.

• DNA is a circular structure found in prokaryotes.

What is the primary function of DNA in protein synthesis?

• DNA provides energy for protein synthesis.

• DNA acts as a catalyst in chemical reactions.

• DNA contains the instructions used to make proteins.

• DNA transports amino acids to the ribosome.

Which nitrogen base does Guanine pair with in DNA?

• Adenine

• Thymine

• Cytosine

• Uracil

What is transcription in the context of protein synthesis?

• Transcription is the process of translating RNA into protein.

• Transcription is the process of copying a segment of DNA into RNA.

• Transcription is the process of synthesizing DNA from RNA.

• Transcription is the process of modifying proteins after synthesis.

How do mutations affect protein synthesis?

• Mutations can enhance the efficiency of protein synthesis.

• Mutations can alter the sequence of nucleotides in DNA, potentially leading to changes in the amino acid sequence of proteins.

• Mutations have no effect on protein synthesis.

• Mutations only affect the structure of proteins, not their synthesis.

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 double-stranded and contains Uracil, while RNA is single-stranded and contains Thymine.

What is the role of RNA in protein synthesis?

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

• RNA is responsible for the replication of DNA.

• RNA acts as a structural component of ribosomes only.

• RNA is involved in the degradation of proteins.

What are the three components of a nucleotide?

• Sugar, Phosphate, nitrogen base.

• Amino acids, Sugars, Fatty acids.

• Glucose, Ribose, Deoxyribose.

• Nucleotides, Proteins, Lipids.

If a DNA strand contains 20% Thymine, what percentage of Guanine is present?

• 20%

• 30%

• 40%

• 50%
