Question

1. refer to the chromosomes in the cells in model 1.

a. draw a single chromosome as it appears in model 1.
b. draw a replicated chromosome as it appears in model 1.
c. how many chromatids are in each replicated chromosome?

Explanation:

a. A single chromosome is a linear structure containing DNA and associated proteins. You would draw a simple rod - shaped structure.
b. A replicated chromosome consists of two identical sister chromatids joined at the centromere. Draw a structure with two parallel rod - like parts connected at a central point.
c. By definition, a replicated chromosome has two chromatids.

Answer:

a. Draw a simple rod - shaped structure representing a chromosome.
b. Draw a structure with two parallel rod - like parts connected at a central point (the centromere) to represent a replicated chromosome.
c. 2
