2 Chromosomes

Question 1

Function

Answer 1

• Carrying hereditary information

- Accurate cell division

Question 2

Structure

Answer 2

A eukaryotic chromosome is made up of linear and tightly packed DNA and proteins called Histones.
A chromosome consists of two chromatids and each chromatid consists of a p arm and an q arm.
The chromatids are attached to each other at the centromere.
At the end of each chromatid is a telomere, which consists of repetitive DNA, that protects the strand.

Question 3

Centrome Types:

Answer 3

• Metacentric
• Submetacentric
• Acrocentric
• Telocentric

Question 4

Found

Answer 4

Pro/Eukaryotic

Question 5

Metacentric

Answer 5

the centromere is in the middle of the chromosome

Question 6

Submetacentric

Answer 6

The centromere is closer to the middle of the chromosome than it is to either end, but the arms differ in length.

Question 7

Acrocentric

Answer 7

The centromere is closer to one end than it is to the middle. There is a large difference in the length of the arms, but each chromatid has two visible arms.

Question 8

Telocentric

Answer 8

The centromere is at the very end of the chromosome. Each chromatid has only one arm.
