3. Compare and contrast the contributions of the following two biologists. What would be the effect on science as a whole if these biologists did not exist? Rosalind Franklin Rosalind Elsie Franklin (25 July 1920 - 16 April 1958) was an English chemist and X- ray crystallographer whose work was central to the understanding of the molecular structures of DNA, RNA, viruses, coal, and graphite. Although her works on coal and viruses were appreciated in her lifetime, her contributions to the discovery of the structure of DNA were largely recognised posthumously. Franklin is best known for her work on the X- ray diffraction images of DNA, particularly Photo 51, which led to the discovery of the DNA double helix for which Francis Crick, James Watson, and Maurice Wilkins shared the Nobel Prize in Physiology or Medicine in 1962. After finishing her work on DNA, Franklin led pioneering work at Birkbeck on the molecular structures of viruses. Her team member Aaron Klug continued her research, winning the Nobel Prize in Chemistry in 1982. Barbara McClintock Barbara McClintock (June 16, 1902- September 2, 1992) was an American scientist and cytogeneticist who was awarded the 1983 Nobel Prize in Physiology or Medicine. McClintock studied chromosomes and how they change during reproduction in maize. She developed the technique for visualizing maize chromosomes and used microscopic analysis to demonstrate many fundamental genetic ideas. One of those ideas was the notion of genetic recombination by crossing-over during meiosis-a mechanism by which chromosomes exchange information. She produced the first genetic map for maize, linking regions of the chromosome to physical traits. She demonstrated the role of the telomere and centromere, regions of the chromosome that are important in the conservation of genetic information.

Analyze the validity of the given statement. Type the word true if the statement is correct. If the statement is incorrect, type false and choose ONLY the word or phrase that made it incorrect. Use a hyphen to separate your answer. ????????:Manila is the capital of the Republic of the Philippines. ➡️ Type: TrueBeijing is the capital of the Republic of the Philippines. ➡️ Type: False-Beijing   1. RNA primers provide the free five prime phosphate end for the DNA processive enzyme to produce the daughter strand. 2. The breakdown of ATP provides the required energy in the catalytic action of DNA ligase and DNA helicase.  3. AP site is produced from the removal of abnormal bases from the affected portions by deoxyribose phosphate lyase. 4. DNA polymerase I and DNA polymerase alpha could add and remove nucleotides from the newly synthesized strand.  5. Telomere shortening is repaired by telomerases by using an RNA template to lengthen the three prime overhang so primase and DNA polymerase…

DNA The larger the DNA fragment, the faster it moves through a gel a) True b) False Listen DNA moves toward the positive charged end of a gel a) True b) False Listen You have 200 copies of a DNA sequence. You perform 10 rounds of PCR. How many copies of the DNA sequence will you have? Just write the number. Do not include any commas or blanks.

7) I have identified a new bacterial species that I can culture in the lab. These bacteria have a unique flagellum (tail used for swimming). I would like to determine if this species has any novel genes involved in flagella development or flagella movement.  What type of genetic screen would you perform and describe how you would carry out the genetic screen to identify genes involved in flagella development or movement. Be sure to include the phenotype(s) you would be looking for in your screen.
