Brief Overview of Macromolecules DNA, RNA, and Proteins
What is “genomics”? --The systematic study of the genome using large-scale DNA sequencing, gene-expression analysis, or computational methods. Genome: the total complement of genes contained in a cell or virus, commonly used to refer to all genes present in one complete haploid set of chromosomes in eukaryotes.
Genome Sizes • Saccharomyces cerevisiae 13 Mb • Drosophila melanogaster 120 Mb • Homo sapiens 3,200 Mb • Fern 160,000 Mb • Amoeba dubia 670,000 Mb
DNA Structure • Base / nucleotide pair: a pair of nitrogenous bases, most commonly one purine and one pyrimidine, held together by hydrogen bonds in a double stranded region of a nucleic acid molecule.
Nucleosides and Nucleotides • DNA = deoxyribonucleic acid adenosine ATP
RNA Structure • Single stranded
Protein Structure • Made up of amino acid chain.
