Detailed explanation-1: -DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).
Detailed explanation-2: -Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell ‘s activities, while RNA converts that code into proteins to carry out cellular functions.
Detailed explanation-3: -Base Pair A base pair consists of two complementary DNA nucleotide bases that pair together to form a “rung of the DNA ladder.” DNA is made of two linked strands that wind around each other to resemble a twisted ladder-a shape known as a double helix.
Detailed explanation-4: -Although each nucleotide in DNA contains identical sugar and phosphate groups, there are four different bases and thus four different nucleotides that can be incorporated into DNA. The four bases are adenine, cytosine, guainne, and thymine, and their structures are shown below.
