When a cell divides, each daughter cell must receive its full complement of genetic material in the form of chromosomes containing DNA, or deoxyribonucleic acid. A chromosome is made up of two long strands of DNA and several types of proteins . A DNA strand is composed of a long backbone of sugar and phosphate units . One of our different nucleotide bases -- A, T, C or G -- hang off each sugar unit. The sequence of the bases encodes genetic information. The three steps in the process of DNA replication are initiation, elongation and termination

Answer:
Which of the following is not part of the nucleotide structure?
a.
<h2>
Sulfate backbone </h2>
c.
Phosphate group
b.
Nitrogenous base
d.
5-carbon sugar
Explanation:
A nucleotide is an organic molecule that is the building block of DNA and RNA. ... A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine. RNA contains uracil, instead of thymine.
The answer is B. fight disease
Out of the following given choices;
a. fructose
b. glycogen
c. sucrose
d. starch
The answer is; B.
Glycogen is only found in animals, bacteria and some fungi. It is analogous to starch (amylopectin) in plants and is also made up of glucose and sucrose polymers. It is highly branched and compact in structure than starch. Glycogen is used as a storage reserve for excess glucose in animals and is stored mainly in the liver and muscles.
