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.
Antlers do not serve as weapons against predators, but are used during the mating season, when the males fight to breed with females. The bucks antlers are shed from January to March and grow out again in in the spring. How long they live: Most white-tailed deer live about 2 to 3 years. The maximum life span in the wild is 20 years, but few deer live past 10 years old. Did you know? White-tailed deer are browse for food at dawn and dusk.
