Dna And Replication Study Guide

desoxyribonucleic acid and issue Study Guide Vocab: Protein: make up of 20 different amino acids; do in ribosomes Polypeptide chains: dour chains of amino acids. Chromosomes: do out of deoxyribonucleic acid and Protein Nucleotides: the subunits making up desoxyribonucleic acid ( north bases, phosphate assemblage and deoxyribose sugar) Purines: double go nitrogen bases and only pair with pyrimidines (adenine, guanine) Pyrimidines: whizz ring nitrogen bases and only pair purines (thymine, cytosine) desoxyribonucleic acid Replication: the subroutine of copy DNA Orgins of Replication: where DNA coming back begins; two DNA strands devote forming Y-shaped areas. Replication Forks: Y-shaped areas Helicase: enzyme that uncoils DNA so it can be replicated; breaks enthalpy bonds too. DNA polymerase: the enzyme that adds new contradictory base pairs. Peptides: the subunits that make up polypeptides. Radical Group: the company that makes a mino acids different from all(prenominal) other and gives the amino acid its unusual properties mRNA: copies the DNA and brings it to ribosomes; long straight chain made out of nucleotides and its made in the nucleus. It copies DNA and leaves through the pores. Contains A,U,G,C. rRNA: makes ribosomes; 100-3000 nucleotides. Globular. Makes up ribosomes tRNA: transfers amino acids to ribosomes where proteins are made.

-------> Codons: sequence of 3 nucleotides Anti-codon: on a tRNA, complementary to a codon. Protein Synthesis: production of proteins; transcription and translation Transcription : process of copying one DNA strand to make ! mRNA; nucleus Translation: decipherment the mRNA into a poly peptide chain; ribosome. fundament: first array of translation Terminations: last stage of translation Mutations: change in nucleotide sequence. Notes: History of DNA Early scientists thought DNA was made of protein because its more complex DNA and proteins make up chromosomes Hershey and Chase o Used...If you need to get a exuberant essay, order it on our website: OrderCustomPaper.com
