Answer 9

[AI-generated answer — Explain Bot]

Question 1:

The correct term for a section of a DNA molecule that codes for proteins is a gene. To get the answer to this question, you would need to have knowledge about genetics and the structure and function of DNA. Specifically, you would need to know that genes are responsible for encoding proteins and that they are found in the DNA molecule.

Question 2:
In order to package the large chromosomes into the nucleus, eukaryotic cells use a family of proteins called histones. To get the answer to this question, you would need to understand the structure and organization of eukaryotic chromosomes. Histones are a type of protein that helps in compacting and organizing DNA in eukaryotic cells.

Question 3:
The correct comparison between prokaryotic and eukaryotic chromosomes is that prokaryotes tend to only have one chromosome while eukaryotes have many. To get the answer to this question, you need to have knowledge about the differences between prokaryotic and eukaryotic cells and their genetic material. Prokaryotes have a single, circular chromosome, whereas eukaryotes have multiple linear chromosomes.

Question 4:
The correct structure of DNA is a sugar-phosphate backbone with nitrogen bases in the middle forming a double helix. To get the answer to this question, you need to understand the structure of DNA. DNA is composed of nucleotides, which consist of a sugar (deoxyribose) and a phosphate group, with nitrogenous bases (adenine, thymine, cytosine, and guanine) attached to the sugar.

Question 5:
The combination of DNA and protein is called chromatin. To get the answer to this question, you need to understand the organization of eukaryotic chromosomes. Chromosomes in eukaryotes are made up of DNA wrapped around proteins called histones. When DNA and histones are condensed together, they form chromatin.
