In you diagram, label the parts of both the donor and recipient cell, draw an arrow, then show the resulting cells and their resulting phenotypes. Label any other special features needed for this process.Genome for C. diphtheriae have about 2,500,000 nucleotides, 87% of them are coding. This ingle circular chromosome contains 2,389 genes from which 2,272 proteins are coded. It does not contain any plasmids. The genome contains Pathogenicity Islands (PAIs), which C. diphtheriae has 13. What is a PAI and what are their characteristics?a. Write the reaction that proves that UV attacks DNA.b. What is a base stacking interaction? How does it help DNA?c. Explain the Sanger method in detail.

- pXO1 and pXO2 are large plasmids – large pieces of DNA that are not the chromosome that can replicate independently of the chromosome. What can a Bacillus anthracis cell with a pXO2 plasmid do that a cell without pXO2 can’t? I need help answering this quwhstion as short as possible based of what is said in the paperShade A if it is True and B if it is False A. True B. False 24. Every phosphate is connected to a sugar 25. Uracil is present in RNA replication 26. 2 haploid cell is the end product of DNA replication 27. Complimentary base pairing is compose of 7 nucleotides 29. New strands are copied and formed from separated strands of DNA 30. 3' to 5' end, 5' to 3' end are the directionality of DNA strandsWhat is an advantage of using mtDNA OmtDNA is a much longer sequence compared to chromosomal DNA mtDNA has a larger genome than chromosomal DNA mtDNA does not breakdown as readily as chromosomal DNA mtDNA changes very quickly and can be used to differentiate closely related bacteria
- Concept 23. A gene is a discrete sequence of DNA nucleotides. This concept describes the discovery of the DNA sequencing technique that made modern biology and bioinformatics possible. The method was later used to sequence the human genome and genomes of many other organisms. This led to the accumulation of great numbers of nucleotide and protein sequences in the numerous databases. The concept 23 web page is here: http://www.dnaftb.org/23/ After reading the Concept page, answer the following questions. What was the Mendel’s definition of a gene? How was it different from the definition by Beadle and Tatum? Describe proteins based on the early sequencing efforts. What was the definition of a protein coding gene based on the genetic code? What are the beginning and ending codons of the gene’s protein coding sequence? What is the name of the method that makes use of a “defective” DNA nucleotide? After reviewing the Animation pages, answer the following…Activity 7. Build Me Up Direction: Construct a cladogram in the template provided using the data provided in the table below.Classifiation of Llfe A new organism was discovered in a deep sea vent at the bottom of the ocean. The researchers collected the sample and made careful observations of it. The picture at right shows a microscopic image captured at 1000X its actual size. Below are some other observations made: • When DNA was isolated from the cell, it was mixed with an equal portion of histone proteins • There are no visible organelles present inside the cell • The specimen seem to die in the presence of oxygen • Able to live in conditions that mimic deep sea vents without any external food source provided Based on these observations, determine each of the following and provide a clear rationale. A) To which domain would you assign this organism? Why? B) Propose a hypothesis of how they obtain nutrients. Are these most likely autotrophs or heterotrophs? Provide a rationale.
