Correct answer: c) Backbone—a phosphate group and a sugar
d) Rungs—bases
The DNA molecule is made up of a molecule called as a nucleotide. It consists of a Phosphate group, nitrogenous base, and a sugar group.
Each nucleotide molecule contains the four nitrogenous bases called as guanine [G], cytosine [C], adenine [A] and thymine [T], the pentose sugar and a phosphate group.
The rungs of the DNA strand are made up of nitrogenous bases and backbone of the DNA strand are composed of sugar and phosphate group.
Answer:
Different genes are expressed in different cells
Explanation:
The instruction is provided to the cell by the genetic material in the form of genes. Genes are the physical segment present on the DNA which can code for a specific protein.
The genes are present in the cells in the condensed form called chromosome which is present in all the cells of the body.
Although all the cells contain the same type of chromosomes or genes but they differentiate to perform different functions.
The differentiation process involves the expression of different genes in different cells as a result of which different proteins are formed in different cells and they perform different functions.
