Questions: Match each molecule with its description. Chromatin Histone Peptidyl transferase Topoisomerase protein around which DNA is wrapped an RNA enzyme that catalyzes bond formation during translation an enzyme that helps prevent overwinding of the DNA during DNA replication DNA and the proteins around which it is arranged

The answer is as follows:

1. Chromatin: DNA and the proteins around which it is arranged
2. Histone: protein around which DNA is wrapped
3. Peptidyl transferase: an RNA enzyme that catalyzes bond formation during translation
4. Topoisomerase: an enzyme that helps prevent overwinding of the DNA during DNA replication

Explanation:

• Chromatin is the complex of DNA and proteins (including histones) that forms chromosomes within the nucleus of eukaryotic cells.
• Histones are proteins that act as spools around which DNA winds, playing a role in gene regulation.
• Peptidyl transferase is an enzymatic function of the ribosome's RNA component that forms peptide bonds between amino acids during protein synthesis.
• Topoisomerase is an enzyme that alleviates the torsional strain generated ahead of the replication fork by transiently breaking and rejoining DNA strands.
