The below mentioned article provides a note on DNA:- 1. DNA Chemistry 2. DNA Replication 3. Carrier of Genetic Information. DNA Chemistry: DNA is found to consist of thread-like particles of high molecular weight in isolated condition. A number of units called nucleotides become linked together and form the nucleic acid. A nucleotide is composed of a molecule of Pentose [...]
The following points highlight the three main laws of genetics proposed by Mendel. The laws are: 1. Law of Dominance and Recessive 2. Factors and their Segregation 3. Dihybrid Cross. Law # 1. Law of Dominance and Recessive: Mendel designated dominant, the character which appears in F1 masking the effect of the factor for the other character, the character which [...]
