Question

I need help with 63 and 64. Thank you so much!!

Question 63 1 pts The table below shows the results of measuring the percentages of the four bases in the DNA of several different organisms. Some of the values are missing from the table. A G 19.9 LI FI I Nitrogenous Bases (%) Human Chicken Bacterium (S. lutea) 28.8 21.5 Based on Chargaff's rules, the percentages of guanine bases in chicken DNA should be around: 28.8% 21.5% 19.9% 13.4%

Answer 1

8.63 According to chargaft srules A = T 6=c A+T - Gtc 1 : 1 ratio of quanine base in chicken DNA. C is given = 21.5%. G = 21.5%. option no. @ is correct 1 so 0.64. According to changatt's rule O= T A+ T = Gtc. we Also write 50%. = 50% I ; 1 in atto form) Criven A = 13.4 So T = 13.4 At T = 26.4 Total sum is Hundred (100) 100- 26.4 = 73.2 G+C = 73.2 C = = 36.6 Of Cytosine in DNA of bacterius S. luteo C= 36.6% optim no. is correct
