Mutation
Mutation is a change in the DNA sequence of an organism’s genetic material. DNA, or deoxyribonucleic acid, is the molecule that carries the genetic instructions for the development and function of all living things. DNA is made up of four chemical bases, adenine (A), cytosine (C), guanine (G), and thymine (T), which are arranged in…
Chromosome
A chromosome is a structure found in cells that is made up of a long strand of DNA, which is the genetic material that contains the instructions for the development and function of all living organisms. Chromosomes are found in the nucleus of eukaryotic cells and play a crucial role in the cell cycle, replication,…
MENDELS LAWS OF INHERITANCE
The first scientific study leading to formulation of laws of inheritance was carried out by Gregor Johann Mendel. Mendel conducted cross-hybridization experiments on garden Pea plant (Pisum sativum) and studied the transmission of characters. Mendel selected garden pea as experimental material because It is easy to cultivate. Pea plant had several true-breeding lines. The plant…
