Question

7.

macromolecule	elements present	subunits (monomers)	function(s)	examples
lipids
proteins
nucleic acids

1. which macromolecule is the most diverse?

1. what is the difference between hydrolysis and dehydration?

1. what was the contribution to dna of the following scientists:

watson & crick
rosalind franklin

1. what is the monomer of dna?

1. dna replication: when is it/what is happening? where does it take place?

Explanation:

The problem involves macromolecules, their components, and related biological concepts, so the subfield of Biology (under Natural Science) is the most appropriate. For question 8, proteins are the most diverse macromolecules due to their various structures (from primary to quaternary) and functions (enzymes, structural, transport, etc.). For question 9, hydrolysis uses water to break polymers into monomers (e.g., breaking a disaccharide into monosaccharides), while dehydration synthesis removes water to form polymers from monomers (e.g., forming a disaccharide from two monosaccharides). For question 10, Watson and Crick proposed the double - helix structure of DNA; Rosalind Franklin provided X - ray diffraction data (Photo 51) that was crucial for determining the DNA structure. For question 11, the monomer of DNA is the nucleotide (composed of a phosphate group, deoxyribose sugar, and a nitrogenous base - adenine, thymine, cytosine, or guanine). For question 12 (assuming it's DNA replication), DNA replication occurs during the S - phase of the cell cycle (in eukaryotes, in the nucleus; in prokaryotes, in the cytoplasm). It is the process of copying DNA to produce two identical DNA molecules, involving enzymes like DNA polymerase, helicase, etc.

Answer:

Question 8

Proteins are the most diverse macromolecule.

Question 9

Hydrolysis: Breaks polymers into monomers by adding water. Dehydration: Forms polymers from monomers by removing water.

Question 10

• Watson & Crick: Proposed the double - helix structure of DNA.
• Rosalind Franklin: Provided X - ray diffraction data (Photo 51) for DNA structure determination.

Question 11

The monomer of DNA is the nucleotide.

Question 12 (assuming DNA Replication)

• When: During the S - phase of the cell cycle.
• What: The process of copying DNA to produce two identical DNA molecules.
• Where: In eukaryotes, in the nucleus; in prokaryotes, in the cytoplasm.
