Read this article to learn about the artificial chromosomes present in human genome. There are four types of artificial chromosomes. They are: (1) Yeast Artificial Chromosomes (2) Bacterial Artificial Chromosomes (3) Mammalian Artificial Chromosomes and (4) Artificial Human Chromosomes. Efforts to clone and sequence the human genome and genomes of intensively studied organisms such as maize, Arabidopsis thaliana, Drosophila, and [...]
For convenience, the cell cycle may be divided into two major phases—the interphase (in which the cell is engaged in its cell-specific or tissue- specific activities) and the mitotic phase (in which the nucleus undergoes division). During mitosis, chromosomes of eukaryotic cells condense, and when stained with basic dyes, the chromatin is easily studied by microscopy. During the interphase of [...]
This article provides information about Chromosomes; its Parts, Functions and Types: Different Parts of Chromosome: (1) Pellicle and matrix (2) Chromonemata (3) Chromomeres (4) Centromere (5) Secondary constrictions (6) Satellite bodies [I] Pellicle and matrix: Each chromosome is bounded by a membrane called pellicle. It is very thin and is formed of achromatic substance. This membrane encloses a jelly-like substance [...]
