- a. Propose three different mutations to prevent initiation, elongation, and termination of bacterial DNA replication, respectively. Explain how/why each mutation would prevent its respective step. (Hint: mutations can be in genes that encode proteins or regulatory DNA sequences) b. In the early 1900s, Avery, MacLeod, and McCarty performed an experiment in bacterial cells to determine whether DNA, RNA, or protein functions as the 'transforming molecule' (i.e. the genetic material). In your own words, how did their experiment (depicted in the figure below) help to answer that question?arrow_forwardA. Refer to the figure below and explain DNA packaging and Describe 1 structural feature/characteristic which makes histones well-suited for attracting and assisting with the packaging of DNA nucleus cel DNA of double helixarrow_forwarda. As a result of the structure of DNA and RNA, replication, transcription and translation are possible. What can nucleic acids do, as a result of their structure, that enables these processes to occur? The figure below shows a simplified schematic representation of a segment of DNA.

- Introduction: The enzyme deoxyribonuclease I (DNase I) is an endonuclease that hydrolyzes the phosphodiester bonds of the double-stranded DNA backbone to yield small oligonucleotide fragments. DNase I is used therapeutically to treat patients with cystic fibrosis (CF). The DNase I enzyme is inhaled into the lungs where it then acts upon the DNA contained in the viscous sputum secreted by the lungs in these patients. Hydrolysis of high molecular weight DNA to low molecular weight DNA in the sputum decreases its viscosity and improves lung function. Animal studies have shown that DNase I is also effective in treating the autoimmune disease systemic lupus erythematosus (SLE). In this disease, the DNA secreted into the serum provokes an immune response. DNase I prevents the immune response by degrading the DNA to smaller fragments that are not recognized by the immune system. Genentech, Inc., the company that produces the recombinant DNase I, was interested in improving the efficiency of…arrow_forwardIntroduction: The enzyme deoxyribonuclease I (DNase I) is an endonuclease that hydrolyzes the phosphodiester bonds of the double-stranded DNA backbone to yield small oligonucleotide fragments.
