Nucleotides play different roles such as being the building blocks of nucleic acids, energy storage, cellular signaling, enzymatic cofactors, etc.
- Nucleotides are the building blocks of nucleic acids (either DNA or RNA).
- These molecules (nucleotides) are composed of one pentose sugar, a nitrogenous base, and one or more phosphate groups.
- In DNA, there are four types of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine and Thymine).
- Adenosine triphosphate (ATP) is a nucleotide that represents the energy coin of the cell, which is used to carry out different metabolic functions (e.g., growth, differentiation, reproduction, etc).
In conclusion, nucleotides play different roles such as being the building blocks of nucleic acids, energy storage, cellular signaling, enzymatic cofactors, etc.

A scientific theory may be revised overtime because it goes to the loop of science which what's the scientific theory to test several times each time a different product may be shown or every now and then a different product may be shown so therefore over time as it goes through the loop of science a scientific theory may change or be revised
        
             
        
        
        
DM occurs when the body cannot produce enough insulin or cannot respond appropriately to insulin. Insulin is a hormone that the body needs to absorb and use glucose (sugar) as fuel for the body’s cells. Without a properly functioning insulin signaling system, blood glucose levels become elevated and other metabolic abnormalities occur, leading to the development of serious, disabling complications.
Many forms of diabetes exist. The 3 common types of DM are:
Type 2 diabetes, which results from a combination of resistance to the action of insulin and insufficient insulin production
Type 1 diabetes, which results when the body loses its ability to produce insulin
Gestational diabetes, a common complication of pregnancy. Gestational diabetes can lead to perinatal complications in mother and child and substantially increases the likelihood of cesarean section. Gestational diabetes is also a risk factor for the mother and, later in life, the child's subsequent development of type 2 diabetes after the affected pregnancy.
