Definition

This term describes a type of chromosome where the central part, called the centromere, is positioned close to one end. This results in one side of the chromosome being significantly longer than the other.

Example

In acrocentric chromosomes, the centromere is positioned close to one end, resulting in one long arm and one short arm.

Conversation

Did you know some chromosomes are acrocentric in shape?

Really? I didn’t know that! What does it mean exactly?

It means the centromere is close to one end, so one arm is much shorter.

That’s interesting! I guess there’s a lot to learn about genetics.

Root Explanation

Acrocentric → It is formed from "acro-" (from Greek "akron", meaning top or peak) and "centric" (from Greek "kentron", meaning center). The word describes something that has its center at the top or peak, often used in a biological context to refer to chromosomes with the centromere located near one end.

Memory Tip

Think of 'acro-' meaning 'top' and 'centric' meaning 'center' — this helps you remember that 'acrocentric' refers to something centered at the top.
