a. To develop ways to map the human genome. b. To develop tools for data analysis of the information. c. To address ethical, legal and social issues that may ari..

It is a comprehensive international effort started in 1990 by molecular biologists to map the entire human genome by determining the complete nucleotide sequence of DNA of each chromoso..

The aim of this project is to grow fruit trees and ornamental plants in urban areas, in private compounds and in common park..

This forms the inner pale zone and contains the Henle's loop and the collecting tubules, present in the form of renal pyramids. The conical pyramids project into the renal pelvi..

Around the cell body are short sensory projections called the dendrons. The fine branches of dendrons are called the dendrites. These short fibres receive messages and pass them on to the cell body or the cyton. The messages from the cyton are carried away by the long axon which end..

Movement involves musculature of the body wall and structures called setae. Setae are hard horny, chitinous structures embedded in the body wall in small pits. About 1/3 of the length of each setae projects out of the surface of the skin. The setae are arranged in the form of a ring in ev..

It is a portion of the large intestine that is not very well developed in man. It is more developed in cattle and other ruminants to accommodate the bacteria that digest the cellulose. In man, it shows a small projection called the appendix. The infection of appendix is called appendicit..

are structures located on the surface of the tongue. They are embedded in the mucosa of the papillae of the tongue. The papillae are projections on the upper surface of the tongue. Each papillae may contain from few to a hundred taste buds and the surface of the tongue may have up to 10..

It is a simple fleshy fruit. It develops from a syncarpous inferior ovary having axile placentation. The pericarp is differentiated into outer thick, leathery epicarp having a number of oil glands, the middle white, spongy mesocarp closely attached to the inner side of the epicarp and the inner me..

Epiblema is the outermost covering of the root formed by single layer of compactly arranged, barrel-shaped, parenchyma cells. The cells are characteristically thin-walled since they are involved in absorption of water. A cuticle and stomata are absent. Some of the epiblema cells are produced ..
