Rh-Incompatibility During Pregnancy
By:
Abha Singh
Rh- incompatibility is a condition that develops when a pregnant woman has Rh-negative blood and the baby in her womb has Rh-positive blood, it is also known as Erythroblastosis fetalis. It is a potentially life threatening blood disorder in a fetus or infant, in this diseade the production of maternal antibodies occurs against the fetal red blood cells.

Hemochromatosis and its Genetic Inheritance
By:
Shalini Balan
What is Hemochromatosis and how it is caused? Hemochromatosis is genetic disorder that is inherited from both the parents .In this condition the amount of iron in the body is usually higher than the required. The body absorbs and stores more amount of iron, which in turn gets stored in the organs like pancreas, liver, and skin. If they are not properly treated and regularly monitored iron abnormalities may lead to damage of the organs.

Genetics of Nitrogen Fixing Microorganisms
By:
Shivika Bhatnagar
In Rhizobium species, nodulation genes together with other symbiotic genes, are located on large-plasmids (Sym plasmids). Sym plasmids vary from 50 to over 600 kb in R. leguminosarum bv. Trofoli to 1200 to 1500 kb in R. meliloti. Nodulation genes, nod and nol genes, are classified as regulatory, common and host specific. Regulation of nod genes is controlled by the nod gene, of which all rhizobia tested so far contain one or more copies. In conjunction with plant flavonoids or other phenolic compounds, nod proteins act as transcriptional activators of inducible nod genes.

Why Sex Chromosomes Evolve So Rapidly?
By:
Shalini Balan
Details about reproductive / sex chromosome and their evolution. In animals with separate sexes, embryos assign to become male or female at an early stage. Often this key decision is made by sex determination genes on the sex chromosomes. The genes concerned in sexual development have not changed much since evolution. In contrast, the sex determination genes and the sex chromosomes themselves are among the most rapidly changing features of the genome.

By:
Syed Amir Manzoor
The article focuses on the significant applications of the vectors in genetic engineering. Vectors are carriers, transporters and may also be termed as vehicles for genetic material. DNA bodies used to transfer alien genetic material to the cells are known as vectors. Vectors are generally classified in to four groups on the basis of their transmitting form e.g. (1) Synthetic chromosomes (2) Plasmids (3) Viruses (4) Cosmids. Most common of these vectors are viruses and plasmids.

Humanized antibodies are the name given to antibodies derived from non human species whose proteins have been modified to enhance their resemblance to natural human antibodies. When therapeutic antibodies are produced in non human immune system (for example mice) their protein sequence are to some extent different from that of natural human antibodies. It is important to humanize these antibodies

Techniques Used in Detection of Genetic Diseases - Part 2
By:
Kanya Sasi
Most of the techniques used in identifying a gene responsible for a genetic disorder can be applied only when there is pre-information about the genes or the gene products. However in many cases where there is no knowledge about the genes or the gene products a different approach has to be used. In such cases the most probable gene resulting in the disorder can be identified by using other methods

Biohazards of Genetic Engineering
By:
Sonali Bhawsar
Recombination consists of joining of DNA from different species, hybridization and its insertion (via plasmid or transposons or virus vectors) into the host cell of other species. It is also known as horizontal gene transfer. It generates novel life forms like hybrid animals, plants or microbes possessing extraordinary characteristics which may prove lethal or harmful with time. DNA recombination is bothered for its unpredicted results on environmental health including plants, animals and microbes. It has been a topic of debate in scientific discussions and conferences.

Gene Walking and Chromosome Jumping
By:
Sonali Bhawsar
Gene walking is basic method of genetic engineering that allows identification of unknown regions flanking a known DNA sequence. Chromosome jumping is also one of the basic tools of molecular biology which involves physical mapping of genome. Jumping the chromosome indicates rapid movement along the chromosome in search of particular gene of interest. Thus it is used to bypass regions difficult to clone and cannot be mapped by gene walking. But walking and jumping processes are correlated.

Drug resistance reduces our ability to cure. Although this resistance is a natural response to the selective pressure of the drug, it worsens by drug abuse, poor patient compliance etc. First line drug-resistance forces an expensive 2nd/3rd line agents against respiratory/immuno/diarrheal infections etc. Resistance against these will make us even more vulnerable to diseases.

Genetic Drifts and Evolution
By:
Sandhya Anand
Evolution is essentially the ability of the species to survive by getting adapted to its environment with changes in genes which are carried over to the next generation. The process of evolution thus involves variations in allele frequencies caused by natural selection, mutations, migrations and genetic drift. The process of genetic drift is the basis of molecular clocks.

The chemical structure of everyone's DNA is the same. Each and every person has a different sequence owing to the presence of millions of base pairs in each person's DNA. These sequences are responsible for the identification of a person. However, because there are so many millions of base pairs, scientists use a shorter method, based on repeating patterns in DNA.

Difference Between Prokaryotic and Eukaryotic mRNA
By:
Nidhi Uppangala
How Prokaryotic and Eukaryotic Messenger Ribonucleic Acid differ? Messenger RNA is a single stranded structure, with no base pairing. It contains bases such as adenine, guanine, cytosine and uracil. Since mRNA is transcribed from the DNA molecule, its sequences are complementary to that of DNA on which they are transcribed.

Mass Spectrometry For the Identification of Protein
By:
Muniba Safdar
What is Mass Spectrometer? It is a technique used to identify proteins from a sample. Its principle depends on mass, i.e. less mass of ion more will be the deflection, similarly more mass of ion, less will be the deflection (source of deflection is magnetic field or electric field). Generally, it is used to find molecular mass/mass to charge ratio of ions in a vacuum.
