One component of the cell theory is A cell is the basic unit of structure and function of all organisms. Thus, option "D" is correct.
The cell contains genetic material in the form of DNA which is passed from the parent cell to the daughter cells after cell division.
All cells are similar in chemical composition as well as in metabolic activities.
All the physiological and biochemical functions usually take place inside the cell.
The activity of the cell depends upon the cell organelles and other cellular parts.
Thus, option "D" is correct.

The four types of nitrogen bases of DNA nucleotides are adenine, thymine, guanine and cytosine.
DNA is defined as deoxyribonuclic acid and it is a polymer made up of two polynucleotide chains that arranged in foiled structure to form a double helix carrying genetic information for the various processes such as growth development functioning and reproduction.
There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.
Friedrich miescher discovered DNA in the year of 1860.
The main function of DNA is to carry information from one generation to another generation this is the reason due to which DNA is also known information molecule.
In our body DNA is found in the nucleus of the cell and it is known as nuclear DNA.
The shape of DNA is double helical structure.
Siblings share only about 50% of same DNA due to the reason of recombination. The life span of DNA is 521 years.
Therefore,the four types of nitrogen bases of DNA nucleotides are adenine, thymine, guanine and cytosine.
