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 [...]

In this article we will discuss about:- 1. Meaning of One-Gene-One Enzyme Hypothesis 2. Significant Steps in the Elaboration of One Gene-One Enzyme Hypothesis 3. Present Position. Meaning of One-Gene-One Enzyme Hypothesis: These are the genes and not the traits that are inherited. So the basic question is how the gene functions to elaborate a phenotype. The question is actually [...]
