Read each question carefully and answer to the best of your ability. This worksheet covers the fundamental processes of DNA transcription and translation.
1. What is the primary product of transcription?
A protein
An mRNA molecule
A DNA molecule
A tRNA molecule
2. Where does translation occur in a eukaryotic cell?
Nucleus
Mitochondria
Ribosome
Endoplasmic reticulum
3. During transcription, the enzyme synthesizes an RNA molecule from a DNA template.
4. A sequence of three nucleotides on an mRNA molecule that codes for a specific amino acid is called a .
5. The genetic code is universal, meaning the same codons specify the same amino acids in most organisms.
True
False
6. In RNA, the nitrogenous base thymine is replaced by uracil.
True
False
7. Briefly describe the role of tRNA in the process of translation.
8. Explain the difference between exons and introns in eukaryotic gene expression.
Match each term on the left with its correct description on the right.
9. Codon
a. The process of synthesizing RNA from a DNA template
10. Transcription
