Entries must fit in at least one of the specific prize categories, and cannot simply gain entrance for being literary or musical.
A DNA molecule is a double helix, a structure that looks much like a ladder twisted into a spiral. The sides of the ladder are made of alternating sugar and phosphate molecules, the sugar of one nucleotide linked to the phosphate of the next.enes are made of DNA, and so is the genome itself. A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA. DNA is long and skinny, capable of contorting like a circus performer when it winds into chromosomes.
Concept 19 The DNA molecule is shaped like a twisted ladder. Earlier work had shown that DNA is composed of building blocks called nucleotides consisting of a deoxyribose sugar, a phosphate group, and one of four nitrogen bases â adenine (A), thymine (T), guanine (G), and cytosine (C).Phosphates and sugars of adjacent nucleotides link to form a long polymer.arlier work had shown that DNA is composed of building blocks called nucleotides consisting of a deoxyribose sugar, a phosphate group, and one of four nitrogen bases â adenine (A), thymine (T), guanine (G), and cytosine (C).
