example in mammals is.
Synthesizing a New DNA strand
called DNA polymerases catalyze the elongation of a new DNA at a replication fork.
Most DNA polymerases require a primer and a DNA template strand. The elongation
is about of 500 nucleotides per second in human cells.Each nucleotide that is
added to a growing DNA strand is a nucleotide triphosphate.
of energy suppliesadenine to DNA and is similar to ATP of energy metabolism.
The difference is in their sugars; dATP has deoxyribose while ATP has ribose.
As each monomer of ATP join the DNA strand it loses two phosphate groups as a
antiparallel elongation of the double
helix affects replication. DNA polymerases add nucleotides only to the free
three prime ends of growing strand therefore a new strand can elongate only in
the specific direction.
one template strand of DNA polymerase synthesizes a leading strand contiously
moving towards the replication fork. To elongate the other new strand called
lagging strand. DNA polymerase must work in the direction away from replication
fork .The lagging strand is synthesized as a series of segments called okazaki
fragments which are joined together by
GIMs with functional information
A crucial step in the interpretation GWAS results is to put the
identified associations into the context of results from other associationStudies,
including associations of genetic variants to Traits at different phenotype
layers. Most recently published WAS studies, therefore, go beyond the mere
reporting of genetic associates’ by combining their results with additionalbylinking
individual association sin a systems level approach and by adding clinical association
data to establish complex gene-to-disease network. However, collecting and integrating.
Publicly available association data still present a major bottleneck in the
evaluation of mg WAS results, in large part due to Fact that data fromdifferent
sources are reported on different, But highly correlated SNP sets.
Application of GIMS for Hypothesis Generation
For deeper functional research. The great potential of mg WASA
hypothesis geerating tool is demonstrated when rediscover sometimes decades
oldfindings from biochemical. Experiments in the setting of modern genomic and
metabolic studies. One interesting example which a synonymous variant in the
coding region of Alanine-glyoxylic results are more and more use as a starting
hypothesis. Amino transferase several Mg linked variant to this changes in

where the authors demonstrated that the rs37369. Polymorphism results in

Telomerase do not prevent the shortening of DNA molecules but they
do postpone of DNA molecules. The erosion of gene near the ends of DNA molecule.
It has been proposed that the
shortening of telomeres is connected to the

cancerous growth by limiting the number of cell divisions. An enzyme called telomerase catalyze this process.
Human genetic metabolism is a very important metabolism in the
human because it plays very important role in the study of inheritance of human.
Itgives many benefits for determine the different metabolic disorders which
occur in the body of human body and cause different variations in the body of
human. These variations some time become beneficial and some time they cause
different diseases in the metabolism of human body. Some variations are neutral

The telomers play very important role in the body of the living
organism such as human and other living organism which have a major genetic system.

role in the genetics of human because transformission like many other processes
occur in the body of living organism. Transcption and translation which occur in the body of human.
These processes also play very major role in the body of living organism such
as human being body and many other bodies of living organisms.
processes take place in the body of living organism which are much important in
the system of body which are necessary for the working of the body of living
organisms like human and many other living organisms. Many variations take
place or may occur in the above processes like transformation or translation or
reduction and many other function which are so beneficial and favorable for the
body function of the living organisms.
human genetic metabolism gives much information about the genetic diseases and
also give information about the ratio of human or death of living organisms

This information plays very important role in the study of genetic metabolism
