What is bioinformatics? • (Wikipedia) Bioinformatics is the application of information technology to the field of molecular biology. • (NIH) Bioinformatics is the field of science in which biology, computer science, and information technology merge to form a single discipline. • (Simply put) Bioinformatics is the acquisition, organization, analysis, interpretation, visualization, and utilization of biological data that may reveal new insights or principles
DNA • Deoxyribonucleic Acid • Basic building blocks of organisms • Located in nucleus of cells • Composed of 4 nucleotides • Adenine (A) • Cytosine (C) • Guanine (G) • Thymine (T) • Two strands bound together • Contains genetic information of individual
Transcription • During transcription, DNA is converted to create mRNA • RNA is processed and non-coding regions removed • Coding regions are converted to form protein • Enzyme (RNA Polymerase) that starts transcription by binding to DNA code .
RNA • Ribonucleic Acid • Contains A,C,G but U (Uracil) instead of T • Single Stranded • May fold back on itself • Needed to create proteins • Move around cells – can act like a messenger • mRNA – moves out of nucleus to other parts of cell
Translation • Synthesis of Proteins from mRNA • Nucleotide sequence of mRNA converted into amino acid sequence of protein • Twenty amino acids • Codon – Group of 3 nucleotides • Amino acids have many codings
Protein • Composed of 20 amino acids
