This video is about the morphology of the chromosome. Chromosomal body has elongated highly coiled DNA fibrils known as chromonema which are embedded in the matrix and matrix is covered with the pellicle. The size, shape and number of chromosome are fixed according to species. Organism having one set of chromosome are Haploid(n), with double set they are diploid, more than two set are known as polyploids.

This video is about the chemical composition of chromosome, which consists of chiefly of DNA, Histone and Non- Histone Proteins. DNA,the Polynucleotide, is the sole genetic material of the organism. Five kinds of Histone proteins help in structural organization of the chromosome and they are highly conserved during evolution among species. There are about 20 Non Histone proteins having regulatory functions.

This is part of lecture presented by Ms Priyanka Khan, Asst. Professor in Biyani Girls College. This lecture is about R.H. Whittaker’s Five Kingdom Concept
According to Five Kingdom Concept of R.H. Whittaker living beings have been categorized into 5 Kingdoms:- Monera, Protista, Plantae, Fungi and Algae. Monerans are kingdom of Unicellular Prokaryotes, Protista are kingdom of Unicellular Eukaryotes, Plantae are kingdom of Multicellular Eukaryote Producers, Fungi, the kingdom of Multicellular Decomposers and Animalia are kingdom of Multicellular Eukaryote Consumers.
