The below mentioned article provides a biology note on habitat. Viable micro-organisms may be found in a very wide range of habitats, from the coldest of brine ponds in the frozen wastes of polar regions, to the almost boiling water of hot springs. Indeed, it is now realized that actively growing bacteria may occur at temperatures in excess of 100°C [...]
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 below mentioned article provides a note on Mendelian laws in the light of modern genetics. Segregation: In the F1 generation of Mendel's monohybrid cross, the plants are heterozygous and their genetic composition is Tt. The phenotype is tall and shows no visible indication of the presence of the gene t, though it is present in the genotype. The two [...]
