DNA (deoxyribonucleic acid) is an organic polymer whose monomer is a nucleotide. A nucleotide is made up of a nitrogenous base (Adenine, Guanine, Cytosine, and Thymine in DNA, Uracil replaces Thymine in RNA), a pentose (5 carbons) sugar (deoxyribose in DNA and ribose in RNA), and a number of phosphate (PO4) groups ranging from 1 to 3 (1 in polymeric form, 2 or 3 when free in solution).

∙ 15y agoDNA - Deoxyribonucleic acid - is made from 2 sugar-phosphate backbones connected by a series of bases. The backbone is made up from Deoxyribose (a ribose sugar with two alcohol groups on it) connected to a phosphate group, which is in turn connected to another sugar in a condensation polymer chain (a chain, that when connected, gives off water). These are connected by nitrogen containing bases. They are named Adenine, guanine, thymine and cytosine. These connect using hydrogen bonds to form the helical structure of DNA. Broken down, this means that DNA contains Carbon, Oxygen, Nitrogen, Phosphor and Hydrogen.

What is molecular evidence or a DNA sequence?
what does molecular evidence mean
If enzymes are bigger or DNA is bigger in molecular size?
Enzymes are smaller than the DNA they process in molecular size. This is because the DNA is a very long string of parts, whereas the enzyme is a single piece.
How does molecular genetics add to your understanding of genes?
molecular genetics adds to our genes by DNA molecules.
What are the requirements for recombinant DNA technology?
gene of interest 2.molecular scissor 3.molecular carrier or vector 4.expression system .These are the requirments for recombinant DNA technology.
What uses bacteria to copy DNA?
They can reproduce very quickly
What molecular units join to form DNA?
DNA (deoxyribonucleic acid) is an organic polymer whose monomer is a nucleotide. A nucleotide is made up of a nitrogenous base (Adenine, Guanine, Cytosine, and Thymine in DNA, Uracil replaces Thymine in RNA), a pentose (5 carbons) sugar (deoxyribose in DNA and ribose in RNA), and a number of phosphate (PO4) groups ranging from 1 to 3 (1 in polymeric form, 2 or 3 when free in solution).
What are units that form that DNA molecules?
They are the nucleotides adenine, guanine, cytosine, and thymine.
What are small molecular units joined together in large molecules called?
Macromolecules.
What are the units that's form DNA molecules?

When did Chargaff discover DNA?
He didnt discover DNA, Erwin Chargaff proposed two main rules in his lifetime which were appropriately named Chargaff's rules. The first and best known achievement was to show that in natural DNA the number of guanine units equals the number of cytosine units and the number of adenine units equals the number of thymine units. The second of Chargaff's rules is that the composition of DNA varies from one species to another, in particular in the relative amounts of A, G, T, and C bases. Such evidence of molecular diversity, which had been presumed absent from DNA, made DNA a more credible candidate for the genetic material than protein.
The primary function of DNA ligase is to?
The primary function of DNA ligase is to reassemble DNA fragments produced by the use of restriction enzymes. The pieces are joined using a process called ligation, which uses the enzyme, DNA ligase which acts as a molecular 'stapler'. The fragments are joined as follows: - sticky-ended DNA fragments are created from two DNA sources using the same restriction enzyme. - The DNA from the two sources is mixed and complementary ends allowed to form complementary base pairs. This process forming loose and temporary join by hydrogen bonding is called annealing. - DNA ligase is then added to form a permanent link.
What is the difference between DNA genes chromosomes?
Genes are basic units of Inheritance and are the templates for the creation of proteins, whereas Chromosomes are the molecular structures within the nucleus that contain genes.
Molecular building blocks of DNA?
Sugar
What is the other name for molecular bonds?
dna
Whether enzyme is bigger or DNA is bigger in molecular size and how do we conclude that?
enzyme is nothing but the protein which is formed from DNA by translation through transcription of a particular region of the DNA . so obviously the DNA is larger than the enzyme in molecular size.
The molecular structure of DNA was deduced?
The molecular structure of DNA was deduced by X-Ray diffractions by Rosalind Franklin. When analyzed by Watson and Crick, the DNA molecule was determined to have a double helix structure.
