- German measles results from an infection of the rubella virus, which can cause a multitude of health problems in newborns. What conclusions can you reach from a nucleic acid analysis of the virus that reveals an A + G/U + C ratio of 1.13?What does the graph imply?An analysis is performed to determine the proportions of each of the four nucleotide bases in the DNA of several tissue samples from various species. The results appear in the table. Human Chicken Yeast E. coli % Adenine % Guanine (A) (G) 31 20 28 21 32 18 26 25 % Thymine % Cytosine (T) 30 29 33 24 Which conclusions can be drawn from this data? (C) 19 22 17 25 The proportion of G is roughly equal to the proportion of C. The proportion of A is roughly equal to the proportion of T. The proportion of pyrimidines is roughly equal to the proportion of purines. The proportion of A-T base pairs is roughly equal to the proportion of G-C base pairs.
- how did we get the number 1x10^6?and 3.98x10^-8?explain??where these number come from?What information cannot be obtained from punnet square?Baker's yeast, Saccharomyces cerevisiae, is a single-celled, diploid fungus (which is, of course, a eukaryote, that is capable of both meiosis and sexual reproduction). Wild type yeast can normally grow on solid or liquid minimal medium; you isolate three mutant strains which are no longer capable of growing on minimal medium alone, however, they can grow on medium supplemented with adenine. All three yeast strains are homozygous for the underlying alleles. When you cross mutant strain 1 and mutant strain 2, the offspring cannot grow on minimal medium alone and require adenine supplementation; when you cross mutant strain 1 and mutant strain 3, the offspring can grow on minimal medium alone and do not require adenine. A. What conclusions can you make about the alleles of mutant strains 1, 2, and 3 and their relationships with each other? B. What phenomenon is occurring in the cross between mutant strains 1 and 3? After crossing the F1 generation of the cross between mutant strains 1…

- Which one of these is correct ? And why are the rest incorrect?For another project, you designed primers 1 and 2 with the sequences shown below. Your lab partner suggests you calculate the primer melting temperatures (Tm) using the formula: Tm = [(A+T) x 2°C] + [(G+C) x 4°C]. Calculate the Tm for Primers 1 and 2 and give your answers in the boxes provided below. You must give your answer as a whole number (no decimal places). Units (°C) are already shown so must not be included in your answer. Primer 1 (forward): 5' TTCGTCTGGTGAACTCAG 3' °C Primer 2 (reverse): 5' CAGGGTATGTCCGTATAT 3' °Cif one base pair of DNA weighs 650 kDA, how much does the entire human genome with 3.3x109 weigh?
