Question
DNA replication occurs in the 5' to 3 direction; that is, new nucleoside triphosphates are added to the 3 end. In general, DNA replicates semiconservatively and bidirectionally. Bacteria are dependent on telomerase to complete synthesis of their chromosome ends. During replication. primase adds a DNA primer to RNA. DNA strand replication begins with an RNA primer. Telomerase is an RNA-containing enzyme that adds telomeric DNA sequences onto the ends of linear chromosomes. MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. Considering the structure of double-stranded DNA, which kind(s) of bonds hold one complementary strand to the other? A) hydrogen B) ionic C) hydrophobic and hydrophilic D) covalent E) van der WaalsExplanation / Answer

DNA replication is the natural procedure of delivering one indistinguishable copies of DNA from one unique DNA particle. This procedure happens in every living life form and is the reason for natural legacy. DNA is comprised of a twofold helix of two reciprocal strands. Amid replication, these strands are isolated. Each strand of the first DNA atom then fills in as a layout for the generation of its partner, a procedure alluded to as semiconservative replication. Cell editing and mistake checking components guarantee close immaculate loyalty for DNA replication
=====================================================
DNA polymerases are a group of chemicals that do all types of DNA replication.[6] DNA polymerases as a rule can't start blend of new strands, however can just augment a current DNA or RNA strand matched with a format strand. To start blend, a short piece of RNA, called a groundwork, must be made and combined with the layout DNA strand.
DNA polymerase includes another strand of DNA by amplifying the 3' end of a current nucleotide chain, adding new nucleotides coordinated to the layout strand each one in turn by means of the production of phosphodiester bonds. The vitality for this procedure of DNA polymerization originates from hydrolysis of the high-vitality phosphate (phosphoanhydride) securities between the three phosphates appended to each unincorporated base. Free bases with their connected phosphate gatherings are called nucleotides; specifically, bases with three joined phosphate gatherings are called nucleoside triphosphates. At the point when a nucleotide is being added to a developing DNA strand, the arrangement of a phosphodiester bond between the proximal phosphate of the nucleotide to the developing chain is joined by hydrolysis of a high-vitality phosphate bond with arrival of the two distal phosphates as a pyrophosphate.
============================================================
Deoxyribonucleic corrosive, or DNA, is a polymer of nucleotides connected together by particular bonds known as phosphodiester scaffolds. The phosphate gathering (PO3) of one nucleotide connections to the hydroxyl gathering (OH) of the accompanying nucleotide. A huge number of these linkages happen inside the DNA polymer. In any case, just four bases: An (adenine), C (cytosine), G (guanine), and T (thymine) constitute the foundation of the atom.
The DNA atom is comprised of two polynucleotide strands interlaced together to shape a long helical structure, the DNA twofold helix. This structure is extremely steady and it happens in light of the fact that the DNA base sets can communicate with different bases in a certain example: an A base on one strand will dependably combine with a T base on the other strand, the C base will dependably match with a G. These mixes (A/T) and (G/C) are called base sets. The two DNA strands are held together by interchain hydrogen bonds. H-bonds match the bases in one bind to the correlative bases in the other chain. (A/T and G/C).
A number components are in charge of the solidness of the DNA twofold helix structure, among them hydrogen bonds. Interior and outside hydrogen bonds balance out the DNA particle. The two strands of DNA remain together by H bonds that happen between reciprocal nucleotide base sets. Two hydrogen bonds happen between the adenosine and the thymine base sets, and between the cytosine and the guanine there are three.
