Question 1

What are polymers?

Answer 1

Large molecules made from long chains of smaller chemical units called monomers

Question 2

What does poly mean?

Answer 2

many

Question 3

What does mer mean?

Answer 3

part

Question 4

What does polymer mean?

Answer 4

Mant parts (like a paperclip chain)

Question 5

What is a monomer?

Answer 5

One part –> single units that make up polymers (like the paperclips)

Question 6

Monomers form long chains of various types, such as what four things?

Answer 6

1. Linear
2. Branched
3. Cross Linked
4. Network

Question 7

What is another word for proteins?

Answer 7

Polypeptides

Question 8

What are proteins/polypeptides?

Answer 8

linear polymers constructed from a set of 20 different amino acids with different side-group chemistries

Question 9

What are the different side-groups?

Answer 9

R1, R2, R3, R4, etc.

Question 10

Biopolymers are (large/small) molecules made up of what?

Answer 10

-large
-repeating smaller units called monomers

Question 11

How are peptide bonds formed? (the reaction)

Answer 11

by condensation reaction that removes a water molecule

Question 12

What exactly happens to form peptide bonds

Answer 12

The carboxyl group (-COOH) of one amino acid reacts with the amino group (-NH2) of another amino acid, linking them together

Question 13

What are Nucleic Acids?

Answer 13

DNA and RNA

Question 14

What are DNA bases?

Answer 14

A, T, C, G

Question 15

What are RNA bases?

Answer 15

A, U, C, G

Question 16

Phosphate Backbone forms what?

Answer 16

the backbone of DNA and RNA, linking the nucleotides together
