Variations existing in the human genome fall into two major sections: sequence repeats and polymorphisms. Essay

Variations existing in the human genome fall into two major sections: sequence repeats and polymorphisms. Essay

1.0 Sequence Repeats.

Sequence repeats consists of two categories, viz., (1) Minisatellites, alternatively referred to as variable number tandem repeats (VNTR) comprise of repeats ranging from 12 to 500 base pairs. An estimated 80% of humans have variable number of repeats in minisatellites. (2) Microsatellites,  are often called short tandem repeats (STR), or, simple sequence repeats (SSR) with repeats comprising approximately 1 to 11 base pairs. Microsatellites are short stretches of repeated DNA found in most genomes that are highly polymorphic. About 0.5% of the human genome is composed of microsatellites and there are a reported 80,000 dinucleotide and 60,000 trinucleotide repeats which are variable in nature (Senate Commission on Genetic Research). They are composed of short segments of DNA consisting of repeated sequences, sandwiched between flanking sequences. Microsatellites are present in the non – coding region of DNA so they do not have any apparent phenotypic effects. Some examples of microsatellites repeat sequences (The Sanger Institute):

Mononucleotide SSR (A)11: AAAAAAAAAAA
Dinucleotide SSR (GT)6: GTGTGTGTGTGT
Trinucleotide SSR (CTG)4: CTGCTGCTGCTG
Tetranucleotide SSR (ACTC)4: ACTCACTCACTCACTC

Although the species which represent each of these classes/orders are very different, they share similar body styles due to specific environmental factors. Also, the phenomenon of convergent evolution often illustrates the power of naturalselection as theorized by the British naturalist Charles Darwin in the 19th century. According to Ernst Mayr, “the same ecological niche or adaptive zone is often filled by exceedingly similar, but entirely unrelated organisms (which) results in the evolution of similarly adapted phenotypes” (222).

As a graduate student at MIT, I applied my knowledge and experience in math and the sciences into research involving a Modeling of the Human Vestibular System at the Man-Vehicle Laboratory. I conducted a project that investigated the dynamic stability of the head, relative to the body, in response to linear accelerations. Head movements in response to linear acceleration were studied in normal and labyrinthine-defective (LD) subjects for anterior-posterior and for inter-aural axis accelerations, and were analyzed in frequency and time domains. The transfer functions of vestibulocollic reflex (VCR), which uses semicircular canal and otolith input and cerivcocollic reflex (CCR), which uses neck proprioceptor input to regulate the head position with respect to the trunk, were developed and analyzed in this project. Substantial software programming using MATLAB and statistical data analysis were also performed.

… The reality of cloning entered the world arena with a sheep named Dolly. Despite Dolly’s fame, cloning techniques have existed since the 1970s, with a process called ‘artificial twinning’ which involved splitting a single ovum into what are considered new embryos and implanting them each into a female to be carried to term. The controversy of cloning has reached new heights as advances in medical technology are bringing the prospects of human cloning closer and closer.
Currently the cloning of stem cells is the Millennium’s ‘Fountain of Youth’ where cloned stem cells could be “much better at replacing tissue damaged by disease or age (New Scientist).” The prospects of cloning being able to cure such diseases as Parkinson’s Disease and Cerebral Palsy make it important not to place a Congressional Ban on cloning.
In a recent New Scientist, these cloned stem cells “may be more vigorous because nuclear transfer – the key step in cloning – restores the “fuses”, or telomeres, on chromosomes, which burn down as cells divide (Westphal).” Medical professionals are taking the initiative to research aspects of cloning that are beneficial to humankind.

To make a protein, two steps must be instituted. The first step is transcription, where DNA information is transcribed into another form of nucleic acid, which can move from the nucleus of the cell to its cytoplasm. The other step is translation, where the language of proteins, or amino acids, is translated from the language of nucleic acids, or base pairs. Protein synthesis can be controlled during transcription and translation (Schwertz, 1999).
