Bio Technology: DNA Testing (Ethnic Point of View)

Biotechnology, Mesothelioma,Gene Therapy, DNA (Deoxyribonucleic Acid), Deoxyribonucleic Acid, DNA Testing, Ethnicity in DNA Testing, Gene therapy for Asbestos, Mesothelioma Victims, DNA and RNA Structure and Function DNA testing has far reaching implications. It is being used not just for serious purposes like forensic science but also to determine the ethnicity of individuals. A particular company, marketing its tests to determine the ethnicity of people calls it recreational genomics. These tests have become extremely common these days and are being employed by a large number of [more...]

As the RNA polymerase binds on to the promoter, the DNA strands begin to unwind. As the RNA polymerase travels through the opposite strand to the coding strand it matches corresponding mRNA nucleotides to the DNA. The mRNA is elongated as the polymerase proceeds. This process is known as elongation. As the polymerase reaches the termination, modifications are required for the newly transcribed mRNA to be able to travel to the other parts of the cell. A cap is added to the mRNA to protect is from degradation. A poly-A tail is added on the end as a protection and template for further process. A [more...]

ISPUB - Insilico Methodolgy - Resistin Involved In Diabesity

Sequence alignment is an arrangement of primary sequence of DNA, RNA, or protein. Identification of regions of similarity. Consequence of functional, structural, or evolutionary relationships between the sequences.BLAST can perform both Global and Local alignment. Tips to improve BLAST searches Don't always use the default parameters View reports Sequence analyses is done using BLASTP for query sequence i;e Resistin protein with the following parameters for given organisms for Resistin is a recently discovered signal molecule, which could help elucidation of the pathophysiology of the insulin [more...]

A simple statistical test for the alleged “99% genetic identity ...

Typical figures published in the scientific literature for the percentage similarities between the genomes of human beings (Homo sapiens) and chimpanzees (Pan troglodytes) range from 95% to 99%. However, in press releases intended for popular consumption, evolutionary biologists frequently claim that human and chimpanzee genomes are 99% identical. Skeptics of neo-Darwinian evolution have repeatedly punctured this”99% myth,” but unfortunately, it seems to have gained widespread credence, due to its being continually propagated by evolutionists! For instance, one often encounters statements [more...]

Numerous consequences of the directional mutational pressure

Certain types of nucleotide mutations are more frequent than other types in a given genome (or in a part of a genome, or even in a concrete gene). So, the term “directional mutational pressure” (Sueoka 1988) in molecular biology reflects the fact that the mutational pressure has the preferable direction. Mutational GC-pressure is the situation when the rates of nucleotide mutations elevating GC-content are higher than the rates of mutations decreasing GC-content (Sueoka 1988). Mutational AT-pressure is the situation when the rates of nucleotide mutations decreasing GC-content are higher [more...]

DNA – Wikipedia version | we must know

A base linked to a sugar is called a nucleoside and a base linked to a sugar and one or more phosphate groups is called a nucleotide. If multiple nucleotides are linked together, as in DNA, this polymer is called a polynucleotide. The backbone of the DNA strand is made from alternating phosphate and sugar residues. The sugar in DNA is 2-deoxyribose, which is a pentose (five-carbon) sugar. The sugars are joined together by phosphate groups that form phosphodiester bonds between the third and fifth carbon atoms of adjacent sugar rings. These asymmetric bonds mean a strand of DNA has a [more...]
