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.
Deer, moose, caribou and elk grow antlers in the spring and summer and shed them in the winter. Many deer hunters and wildlife watchers eagerly search the woods in winter and early spring for sheds, the discarded antler racks from buck deer. People sometimes call these horns, but these are antlers, not horns. Antlers are temporary projections of bone grown and shed each year. Though the bone looks quite solid, it has a honeycombed structure at the microscopic level. Antlers arise from a pair of pedicels, knobby, skin-covered nubs atop the buck's skull. The pedicles are the âbuttonsâ between the ears of a buck fawn.
