Chapter 4 Translation And Protein Structure

Question 1

What re the four levels of a protein structure?

Answer 1

1 based on DNA sequence
2 due to h bonds in the back bone not in the R group
3 R group has many interactions
4 protein sub units interacting with one another

Question 2

What are the three main shapes of a protein?

Answer 2

Helix and sheet and linear

Question 3

What is a denatured protein?

Answer 3

A protein that has been unfolded and therefore loses it’s function

Question 4

What are chaperons?

Answer 4

Proteins in cells that help fold slow folding or denatured proteins

Question 5

Know the components of translation

Answer 5

Ok

Question 6

What are the two main units of a ribosome?

Answer 6

The large subunit and the small subunit

Question 7

Know the structure of tRNA and why the anticodon is 3’ to 5’

Answer 7

Ok

Question 8

Know how to use the standardized amino acids table 4.1

Answer 8

Ok

Question 9

Define wobble

Answer 9

5’ base in the tRNA anti codon that can base pair with multiple bases at the 3’ position in the codon

Question 10

Know the difference between pro and eukaryotic translation

Answer 10

Ok

Question 11

Know the structure of the hydrophobic amino acids, hydrophillic and special.

Answer 11

Hydrophobic are mostly C and H

Hydrophillic are mostly O and N
