Q

Describe DNA structure

A

DNA is made up of 2 polymer chains that are held together in a double helix. Each polymer chain can be made from 4 different monomers.

Q

How are polyamides formed?

A

From 2 different monomers - diamine and dicarboxylic acid

17
Q

What are polymers?

A

Polymers are very large molecules made when many smaller molecules (monomers) join together, end to end.

18
Q

What are monomers?

A

Monomers are small reactive molecules, mostly organic, that can join with other similar molecules to form very large molecules (polymers).

19
Q

What is addition polymerisation?

A

In addition polymerization, monomers react to form a polymer without the formation of by-products. Addition polymerizations usually are carried out in the presence of catalysts.

20
Q

What happens to the bonds during addition polymerisation?

A

The C=C double bond in the alkene breaks open to allow the alkene molecules to join together to form a single product , so it is an example of an addition reaction.

21
Q

What is a typical use for polythene?

A

packaging film, garbage bags, grocery bags, insulation for wires and cables

22
Q

What does DNA stand for?

A

Deoxyribonucleic acid

23
Q

DNA is an example of what type of polymer

A

Natural polymer
