With atomic data, computers nowadays generate graphic images of the molecules on high-resolution screen. Computer modeling of protein began as early as The computer-generated models depict not only the properties of amino acids in a protein but also help to understand the protein function.
Computer graphic models is the Glowing coal Uses : Protein structure helps in understanding biomolecular arrangement in tissue or cellular architecture. Protein structures, protein models and computer aided graphic models help to understand biological reactions mediated by enzymes proteins.
Graphic models provided by computers are valuable to predict which fragments of a medically important protein can be used to design drugs and vaccines. Proteomics also helps in chemical industries to manufacture drugs, various chemical compounds and enzymes.
Describe the karotyping of human chromosomes The 23 pairs of chromosomes in human are classified into seven groups viz, A-G based on position of centromere.
Group A includes 1, 2 and 3 chromosomes. It includes the largest chromosomes. Metacentric with two equal arms.
Group B : Group B includes 4 and 5 chromosomes. Submetacentric with two unequal arms. Group C : Group C includes 6,7,8,9,10,11,12 and X chromosomes. This is the largest group Submetacentric with two unequal arms.
The X chromosome resembles the chromosome 6 in this group. Group D includes 13,14 and 15 chromosomes.
Acrocentric Group E includes 16,17 and 18 chromosomes. Meta or submetacentric. Group F includes 19 and 20 chromosomes. Group G : Group G includes 21, 22 and Y chromosomes.
Explain Dr Ian Wilmut's cloning mechanism. S Dr. Ian Wilmut has produced a cloned sheep called Dolly by nuclear transplantation method. To produce cloned sheep he took the udder cell which is a somatic cell with diploid number of chromosomes.

An egg cell was also removed from a donor sheep. The egg cell cannot grow into a new sheep on its own because it only has half a set of chromosomes n. The body cell cannot grow into a new sheep on its own because it is not a reproductive cell.
So udder cell nucleus 2n was removed. Similarly the egg cell nucleus n was also removed.
The nucleus of the somatic cell Udder was injected into the enucleated egg. The egg after the nuclear transplantation comes to possess full set of chromosomes viz. The egg was then transplanted back into the uterus of the sheep from which it was removed. The egg also can be transplanted to a new surrogate mother for development. The egg cell grew and developed into a sheep Dolly.
This cloned sheep is genetically identical to the donor sheep, which donated the diploid nucleus of its somatic cell and not the sheep which donated the egg cell.
It helps to know more about the diseases. It helps to understand more about the fundamental biology and the thread of life, - the DNA.
It paves the way for the medical and bio engineering applications. It helps to apply the biophysical and biotechnologicl principles to biological studies. In turn, it will help to design new drugs and new chemical compounds to be used in health and environmental management respectively. What is database? What are its types?
Organogenesis of frog, Development of Chick, Development of Chick Based on hours of Incubation, Development of Mammal, Organogenesis of Chick and Mammals, Development of Foetal Membranes in Chick Development of foetal membranes in mammals, Placenta, Sexual Cycles, Pregnancy and Birth, Neoteny, Gradient theory, Morphogenetic fields, Organizer, Nuclear Transplantation, Nucleocytoplasmic interaction, Differentiation, Metamorphosis in Amphibia, This disorder is inherited as a Mendelian recessive.
Group C: S 1. Green stick fracture: The egg also can be transplanted to a new surrogate mother for development.

Skin also helps in the formation of vitamin D. The egg was then transplanted back into the uterus of the sheep from which it was removed. Cancer, Proteomics also helps in chemical industries to manufacture drugs, various chemical compounds and enzymes.
