WebThe central portion of this molecule contains five carbon atoms arranged in the shape of a ring, and each carbon in the ring is referred to by a number followed by the prime symbol ('). WebFor example, adenine (A) is always paired with thymine (T), and cytosine (C) is always paired with guanine (G). This is because hydrogen bonds hold the nitrogen atoms together. This …

WebThere is a second nucleic acid in all cells called ribonucleic acid, or RNA. Like DNA, RNA is a polymer of nucleotides. Each of the nucleotides in RNA is made up of a nitrogenous base, a five-carbon sugar, and a phosphate … WebIons make up many important molecules needed by plants for survival. In chlorophyll, the main photosynthesising component of plants, the central ion is magnesium, and the large organic molecule is a porphyrin. The porphyrin contains four nitrogen atoms that form bonds to magnesium in a square planar arrangement. Phosphate ions are required for the … greek theatre facts ks3

WebAt the most basic level, all DNA is composed of a series of smaller molecules called nucleotides.In turn, each nucleotide is itself made up of three primary components: a nitrogen-containing ... WebHumans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 13, one copy inherited from each parent, form one of the pairs. Chromosome 13 is made up of about 115 million DNA building blocks (base pairs) and represents between 3.5 and 4 percent of the total DNA in cells. DNA is a long polymer made from repeating units called nucleotides. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds. Both chains are coiled around the same axis, and have the same pitch of 34 ångströms (3.4 nm). The pair of chains have … flower delivery redwood city
