What is the nucleotide in DNA?
What is the nucleotide in DNA?
Listen to pronunciation. (NOO-klee-oh-tide) A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).
What did Rosalind Franklin discover about DNA?
The discovery of the structure of DNA in 1953 was made possible by Dr Rosalind Franklin’s X-ray diffraction work at King’s. Her creation of the famous Photo 51 demonstrated the double-helix structure of deoxyribonucleic acid: the molecule containing the genetic instructions for the development of all living organisms.
What is the monomer of DNA?
nucleotides
The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T).
Who first discovered DNA?
Friedrich Miescher
Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.
How is uracil made?
The most common way to synthesize uracil is by the condensation of malic acid with urea in fuming sulfuric acid: C4H4O4 + NH2CONH2 → C4H4N2O2 + 2 H2O + CO. Uracil can also be synthesized by a double decomposition of thiouracil in aqueous chloroacetic acid.
What means antiparallel?
parallel but oppositely directed
Definition of antiparallel : parallel but oppositely directed or oriented antiparallel electron spins two antiparallel chains of nucleotides comprise DNA.
How many siblings did Rosalind Franklin have?

How many monomers are there in DNA?
four monomers
DNA are polymers composed of four monomers known as nucleotides. Together, they join in varying combinations forming a long strand of the structure. DNA is made up of 4 amino acids – adenine, cytosine, guanine and thymine.
What are the 4 monomers?
There are four main types of monomer, including sugars, amino acids, fatty acids, and nucleotides. Each of these monomer types play important roles in the existence and development of life, and each one can be synthesized abiotically.
Who discovered double helix?
James Watson and Francis Crick
Two weeks later James Watson and Francis Crick, at the Cavendish Laboratory at Cambridge, built their now celebrated model of DNA as a double helix.
What sugar is found in DNA?
deoxyribose
The sugar in DNA is deoxyribose.
