Answer #1

1) eukaryotic chromosome is a linear DNA molecule, packed using proteins called histones, DNA is packed over histones to form chromatin, chromatin is then condensed to form chromosomes, so the answer is

b) one long DNA molecule associated with many proteins

2) mitosis is equational division number of chromosomes in both parent cell and daughter cells are the same, also the daughter cells are genetically indentical to the parent cell.

so if a diploid cell undergoes mitosis, two diploid daughter cells aare produced.

b) genetically unique diploid somatic cells

1. a. It’s estimated that each human somatic cell contains two copies (one on each homologous chromosome) of about 21,000 genes. If you took a close look at one of these (differentiated cells), would you expect all copies of these 21,000 genes to be actively making proteins at any one time?  If you say yes, explain why (generally) it would be advantageous for a cell to actively express all of its genes.  If you say no, explain why (generally) it would be...
