Match the different levels of protein organization with their definition.
levels of organization:
1. primary structure
2. secondary structure
3. tertiary structure
4. quaternary structure
definitions:
a. linear sequence of amino acids in the polypeptide chain
b. three-dimensional structure of a polypeptide
c. highly regular local sub-structures such as α-helix and β-pleated sheet structures
d. three-dimensional structure of a multi-subunit protein
select one:
a. 1-c, 2-d, 3-b, 4-a
b. 1-a, 2-c, 3-b, 4-d
c. 1-d, 2-a, 3-b, 4-c
d. 1-a, 2-b, 3-d, 4-c
e. 1-c, 2-d, 3-a, 4-b

The protein undergoes multiple modifications in order to perform it's function and the structural significance of each type is given below.

Option B

Explanation:

The protein definitions are as follows:

Primary structure- Linear sequence of amino acids in the polypeptide chain.

Secondary structure- Highly regular local sub-structures such as α-helix and β-pleated sheet structures.

Tertiary structure- It is the Three-dimensional structure of a polypeptide.

Quatenery structure- Three-dimensional structure of a multi-subunit protein.

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
