The amino acid sequence of a protein is determined by:
It shape
Its secondary structure
The DNA sequence
The carbohydrates
What makes up a secondary structure? select all that apply
Pleated Beta Sheets
Double Helix
RNA
Alpha Helices
What is true about blood types? select all that apply
Blood type O- can only receive blood from type O-
The antigens on the red blood cells determine blood type
If you have type A blood, you also have antibodies against type A antigens (anti-A antibodies)
Someone with Type AB+ blood can receive blood from any other blood type
This describes the sequence of amino acids which ultimately determines the 3D structure of a protein
Primary Structure
Secondary Structure
Tertiary Structure
Quaternary Structure
