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.ranscription is carried out by a DNA-dependent RNA polymerase that copies the sequence of a DNA strand into RNA. To begin transcribing a gene, the RNA polymerase binds to a sequence of DNA called a promoter and separates the DNA strands.
Whitetail bucks can lose their antlers beginning as early as mid to late December. However, most bucks won't start to shed their antlers until late January or early February depending on where you are in the country. Some bucks will still have their antlers as late March.
During this time, damage done to the racks tends to be permanent. Healthy deer in some areas that are well-fed can have eight-point branching antlers as yearlings (1.5 years old). The number of points, the length, or thickness of the antlers is a general indication of age, but cannot be relied upon for positive aging.he white-tailed deer (Odocoileus virginianus), also known as the whitetail, is a medium-sized deer native to the United States, Canada, Mexico, Central America, and South America as far south as Peru and Bolivia.
