The Pulitzer Prize does not automatically consider all applicable works in the media, but only those that have specifically entered. There is a $50 entry fee, paid for each desired entry category.) 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.
A molecule of DNA is double-stranded. The molecule has the shape of a double helix, typically right handed (B form DNA). The DNA molecule consists of two complementary strands oriented in an antiparallel fashion.Each strand is composed of nucleotides.A nucleotide consists of a base (a purine or pyrimidine), a sugar (between the other two components) named deoxyribose, and a phosphate group. Nucleotides are linked to each other via phosphodiester bonds, forming a sugar-phosphate backbone to each strand.he twisted ladder metaphorA DNA molecule is often likened to a spiral (or twisted) ladder. In this analogy, the rungs of the ladder are the base pairs (A-T and G-C). The sides of the ladder are the sugar-phosphate backbones of the two strands.
