Understanding Transcription and Translation

What is the primary goal of transcription?

• To replicate the entire DNA

• To divide cells

• To produce proteins directly from DNA

• To convert DNA into RNA

Which of the following is true about gene expression?

• It only occurs during cell division

• It involves copying the entire DNA

• It is the same as DNA replication

• It is a normal activity in all cells

In eukaryotic cells, where does the mRNA go after transcription?

• It stays in the nucleus

• It goes to the ribosomes in the cytoplasm

• It is immediately translated into protein in the nucleus

• It is degraded in the nucleus

What is the main difference between transcription in prokaryotes and eukaryotes?

• Eukaryotes do not perform transcription

• Transcription occurs in the cytoplasm in prokaryotes

• Prokaryotes use a different genetic code

• Prokaryotes have a nucleus

What is the role of RNA nucleotides during transcription?

• They form the backbone of DNA

• They pair with DNA bases to form mRNA

• They are used to replicate DNA

• They are not involved in transcription

Which base is found in RNA but not in DNA?

• Thymine

• Adenine

• Uracil

• Cytosine

What happens to the DNA double helix after transcription?

• It reforms by rejoining the hydrogen bonds

• It remains separated

• It is degraded

• It is converted into RNA

What is the main purpose of mRNA?

• To serve as a template for protein synthesis

• To transport amino acids

• To replicate DNA

• To store genetic information

How does the mRNA differ from the DNA template?

• It has thymine instead of uracil

• It is identical to the DNA template

• It has uracil instead of thymine

• It is double-stranded

What is the next step after transcription in eukaryotic cells?

• DNA replication

• Cell division

• Protein folding

• Translation
