DNA transformation

Double helix

• 
• 
• 
• 
• 

Helix

• A circular structure with no twists, like a ring

• A three-dimensional spiral shape that curves around a central axis

• A flat straight line extending infinitely in one direction

Double chromosome

• 
• 
• 
• 
• 

DNA wrapped around histone

• 
• 
• 
• 
• 

Nucleosome coiled into a chromatin fiber

• 
• 
• 
• 
• 

Wrapped

• To cut something into pieces

• To cover something with paper or another material

• To fold something around an object without fully covering it

Duplicate chromosome

• the chromosome is going to split into two identical chromatids

• the chromosome remains in one piece, with no change

• The chromosome shrinks into a smaller size

Futher condensation of chromatin

• 
• 
• 
• 
• 

Coiled

• To tie something into a knot

• To stretch something in a straight line

• To twist something into circles or spirals

“Condensation” in biology:

• It becomes more tightly packed

• It becomes more spread out

• It loses all structure and becomes a liquid
