Deoxyribonucleic acid (DNA) is usually called the blueprint of life. Deoxyribose is a monosaccharide that has a key function in the synthesis of deoxyribonucleic acid. One less oxygen-containing hydroxyl group occurs in deoxyribose sugar. Nucleic acid, d…

DNA as the Genetic Material

DNA, or deoxyribonucleic acid, is a long polymeric nucleic acid molecule discovered in the late 1930s. It is a polymer; a long chain-like molecule made up of several monomers connected in a sequence. It possesses certain characteristics that qualify it a…

Genetics

The significant branch in science which involves the study of genes, gene variations, and the organism's heredity is known as genetics. It is also used to study the involvement of a gene or set of genes in the health of an individual and how it prevents …

DNA Replication

The mechanism by which deoxyribonucleic acid (DNA) is capable of producing an exact copy of its own is defined as DNA replication. The DNA molecules utilize a semiconservative method for replication.

Illustrate some steps involved in DNA replication :Suppose the following base sequence was found in a segment of one strand of a DNA molecule: 3’ A-A-T-A-C-C-T-C-C-T-A-A-C-T 5’ What would be the bases in the complementary strand? Label the 3’ and the 5’ ends. Illustrate the DNA molecule below. Label the 3’ and the 5’ ends of both strands. Separate the above DNA molecule up to the seventh base. Add one primer for the leading strand complementary to the first base Adenine of the template strand. Add one primer for the lagging strand complementary to the seventh base Adenine of the template strand. Illustrate the DNA molecule. Label the 3’ and 5’ ends. Elongate the new strands up the seventh base by adding DNA bases complementary to the template strand. Illustrate the resulting DNA molecule. Label the 3’ and the 5’ ends of the template strands and the complementary strands. Elongate the new strands up the seventh base by adding DNA bases complementary to the template strand. Illustrate…
