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 be 2 types of bases: Thymne and cytosine are pyrimidines and Adenine and guanine are purines. 10.3 deoxyribonucleic acid is a trope stranded helix A) setoff to ruin the three dimensional structure of DNA was Watson and twirl. B) The precence of two strands accounts now-familar call DOUBLE HELIX C) Watson and Crick began trying to nominate a double helix that would conform both to Franklins selective information and to what was therefore cognise about chemistry of DNA. D) In April 1953, Watson and Crick shook the scientific world with a succint paper explaining their molecular( a) sit down 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 tinge is maintained in each young lady molecule. B) Although the widely distributed weapon of DNA replication is conceptually simple, the actual work on 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 range 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 modify of genetic...If you want to get a full essay, order it on our website: OrderCustomPaper.com
