Chapter 10 Outline Biology

Chapter 10 Outline 10.1 Expierments showed that desoxyribonucleic acid is the genetic material A) bacterial viruses ar called bacteriophages, or phages for short. 10.2 desoxyribonucleic acid and ribonucleic acid argon polymers of nucleotides A) A sugar-phosphate backbone is a repeating pattern of sugar-phosphate-sugar-phosphate B) There are 2 types of bases: Thymne and cytosine are pyrimidines and Adenine and guanine are purines. 10.3 desoxyribonucleic acid is a trope stranded helix A) introductory to ruin the three dimensional structure of DNA was Watson and hayrick. B) The precence of deuce strands accounts now-familar call DOUBLE HELIX C) Watson and Crick began trying to force a double helix that would conform both to Franklins selective information and to what was hence cognise about chemistry of DNA. D) In April 1953, Watson and Crick shook the scientific world with a succint paper explaining their molecul ar(a) object lesson for DNA in the journal Nature. 10.4 DNA replication depends on proper(postnominal) base pairing. A) This model for DNA replication is known as the semi conservative model because half of the parental scintilla is maintained in each young lady molecule. B) Although the prevalent weapon of DNA replication is conceptually simple, the actual run involves obscure biomchemical gymnastics. 10.

5 DNA replication proceeds in two directions at many sites simultaneously A) The enzymes that link DNA nucleotides to a growing daughter strand, called DNA POLYMERASE. B) DNA ligase then links the pieces together into a single DNA strand. ! C) In addition to their roles in llinking nucleotides togeter, DNA polymerases carry out a proofreading step that quickly removes nucleotides that allow base-pairing incorrectly during replication. 10.6 The DNA genotype is expressed as proteins, which provided the molecular basis for phenotypic traits. A) The train of command is from DNA in the nucleus of the cell to RNA to prtein synthesis in the cytoplasm. B) The two main stages are transcription, the impart of genetic...If you want to get a full essay, order it on our website: OrderCustomPaper.com
