DNA And The Double Helix Design
DNA, the unremarkably used acronym for deoxyribonucleic acid, is the carrier of the genetic code for most life history organisms. DNA contains the genetic codes that determine eye color, hair color, and sometimes diseases. Each trait that passes from parent to offspring is the result of reading carried by DNA.
Possible Reasons For The Double Helix Shape
DNA has a double helix shape that is functional and useful in several ways. According to The National Center For Biotechnology tuition (2004):
The chemical nature of the bases in double-stranded DNA creates a clear twisting force that gives DNA its characteristic gently coil structure, known as the double helix. The two strands are connected to all(prenominal) other by chemical pairing of each base on one strand to a peculiar(prenominal) partner on the other strand. ampere (A) pairs with thymine (T), and gibibyte (G) pairs with cytosine (C). Thus, A-T and G-C base pairs are said to be complementary.
This complementary base pairing is what makes DNA a suitable scrap for carrying our genetic information—one strand of DNA throw out act as a template to direct the implication of a complementary strand. In this way, the information in a DNA sequence is readily copied and passed on to the next multiplication of cells.
Because of the strict order of the chemical pairing, the double helix origination facilitates the correct bonding of the appropriate chemical bases. However, some scientists give notice that the double helix design may also second to increase the physical strength of the gene. Gene construction is anti-parallel, message the strands run in opposite directions. Because of hydrogen bonding between the base pairs, an unequal number of hydrogen molecules exist on each side. Two hydrogen bonds exist between Adenine and Thymine and three between Guanine and Cytosine, and...If you want to kick the bucket a full essay, order it on our website: Orderessay
