The human genome is 3.3 x 109bp in length. cytosine: [noun] a pyrimidine base C4H5N3O that codes genetic information in the polynucleotide chain of DNA or RNA compare adenine, guanine, thymine, uracil. If all adenine bonds to thymine and all cytosine pairs with guanine, then the sum of all adenine equals the sum of all thymine in a DNA molecule. Point o molecular weight of this compound is 126 point, let's right, 126.13 grams per mole, okay and then for the third question i mean the third compound is ganin, so the formula for that is c, 5, h, 5 and 5 and 1 oxygen so molecular weight for That for that is 12.01 multiplied by 5, plus 6, hydrogen, so 1.01 times 5, and then we have 5, Since adenine and thymine only have two hydrogen bonds, C-G base pairs are slightly more strongly attached than A-T or A-U base pairs. In DNA, adenine pairs with thymine (A = T) meaning adenine is complementary with thymine (and visa versa).

One molecule of DNA can contain hundreds even millions of nucleotides. These hydrogen-bonded nitrogenous bases are often referred to as base pairs. The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Mnemonic in case you don't wanna logic it out: Got A Tattoo UnderCover. 100% DNA subtract 40% gives you 60% DNA percentage left over meaning both cytosine and guanine are 30% each. Remember that complementary base pairing works like a lock and key, so there's only one orientation in which hydrogen bonding will work. Since the carbons in the sugar are numbered one to five, the sugar end of the strand is called the 3' end and the phosphate end of the strand is called the 5' end. It's an important base because it's used not only in DNA and RNA, but also for the energy carrier molecule ATP, the cofactor flavin adenine dinucleotide, and the . The chemical structure of cytosine (C) is {eq}C_{4}H_{5}N_{3}O {/eq}. Professor Pear: Nucleic acids are the molecules that cells use to store, transfer and express genetic information. Exact M.W. Guanine is a purine derivative. The first process is hydrolytic deamination of adenine, then oxidation with formic acid of the hypoxanthine previously formed, and . 10.1 Intermolecular Forces - Chemistry 2e | OpenStax Comparing Cellular Respiration to Burning Fossil Fuels. Gross et al.22 and our group10,38 specific hydrogen bond interaction between the nucleotide pairs polymerized with ATRP unprotected adenine- and thymine- adenine-thymine and guanine-cytosine, known as Watson- based monomers using polyethylene glycol macroinitiators in Crick base pairing, has also been employed in polymer order to obtain .
