The levels of protein structures are: PRIMARY, SECONDARY AND TERTIARY STRUCTURES.
The amino acid sequence and the bonding types between the amino acids determine the structures of proteins. Protein structures also determines the function of a protein, if a protein losses its structure it will not be able to perform its function again.
Functional groups play an important role in the formation of protein structure.Functional groups also participates in specific biochemical reactions in the body thus enabling the proteins to perform their functions.
Adenine, thymine, guanine, and cytosine
adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
Answer:
is used by commercial airplanes
Explanation:
The stratosphere is used by most commercial airplanes. This is because this layer of earth is stratified and more stable.
- The lowest level of the atmosphere is the troposphere.
- This layer is where all the bulk of the atmospheric gases are domiciled.
- Weather conditions occur here.
- This layer is not safe for flight due to its turbulent nature.
- The ionosphere is responsible for the transmission of radio signals around the earth.
- The earth's weather occurs in the region of the troposphere.
