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.

identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
