A galvanic cell was constructed using Zn/Zn2+ and Cu/Cu2+. Given the standard reduction potentials for Zn and Cu, which metal would be the anode?Cu2+ + 2e- –> Cu             = 0.34VZn2+ + 2e- –> Zn             = -0.76V

What is the molality of a solution containing 5.20 moles of CaCl2 in 1.13 kg of H2O?

Label each of the following changes as:  i) a synonymous mutation, ii) a non-synonymous substitution, iii) a stop-loss mutation, iv) a nonsense (stop-gain) mutation. (A genetic code table is below).   A) UGA –> UCA   B) UAC –> UAA   C) AGA –> AAA   D) AGA –> CGA    

Colorblind 1 Your next project is to genetically map the locus for color blindness, an X-linked recessive trait, with respect to simple sequence repeat (SSR) markers. Like many X-linked recessive traits, colorblindness is usually found in males. However, the mutant allele frequency is sufficiently high that colorblind females do occur. In this problem, + is the allele that leads to normal vision, and clr is the allele associated with color-blindness. Assume complete penetrance and no new mutations. The family below has been genotyped for two SSR markers – there are 2 alleles for SSR 72 (Z&W) and 3 alleles for SSR 73 (a,b, & c).  The mother is deceased; thus, her DNA has not been analyzed.  Below the pedigree are the results from the DNA analysis – the heavier bands indicate more DNA.    A) What is the (deceased) mother’s genotype at SSR72?   B) What is the (deceased) mother’s genotype at SSR73?   C) What is the most likely phase relationship between the alleles at SSR72 and the color blindness locus in the mother. D) What is the most likely phase relationship between the alleles at SSR73 and the color blindness locus in the mother.
