Question

Which of the following is true about the differences in genome structure between eukaryotes and prokaryotes? I. A eukaryotic chromosome is linear and a prokaryotic chromosome is circular. II. In both eukaryotes and prokaryotes, DNA is wrapped around histone proteins to form a nucleosome. III. Prokaryotic genomes contain fewer repetitive sections than eukaryotic genomes. A. I only B. I and III C. II and III D. I, II and III A codon is a segment of an mRNA molecule that codes for one amino acid in a polypeptide chain formed during protein synthesis. Which of the following correctly describes the chain of events that occurs in the synthesis of a polypeptide? A. Specific RNA codons cause amino acids to line up in a specific order: tRNA anticodons attach to mRNA codons: rRNA codons cause protein molecules to cleave into specific amino acids. B. DNA generates mRNA in the nucleus: mRNAmoves to the cytoplasm and attaches to a tRNA anticodon: an operon regulates the sequence of events that causes amino acids to line up in their appropriate order. C. DNA generates tRNA: the tRNA anticodon attaches to the mRNA codon in the cytoplasm: tRNA is carried by mRNA to the ribosomes, causing amino acids to join together in a specific order. D. DNA generates mRNA: mRNA moves to the ribosomes, where a tRNA anticodon binds to an mRNA codon, causing amino acids to join together in their appropriate order.

Explanation / Answer

The correct answer is:D.I , II , III

Reason: All the above options are differences between prokaryote and eukaryote genome.

The correct answer is: D.

Reason: Above sequence is the correct sequence of synthesis of polypeptide.
