A bacterial gene is known to spontaneously mutate at a high frequency. A study of one mutant gene product shows that the mutant protein made is shorter than the wildtype protein by four amino acids. The wildtype gene has been cloned and sequenced. It has a region of repeated sequences that code alternately for proline and threonine (see below).Met Pro Thr Pro Thr ..........5'...ATG.........CCC ACG CCC ACG CCC ACG CCC ACG CCC ACG.......TGA....3'a) Clearly explain, using diagrams, how a deletion of four codons could occur in this region and be passed on to progeny.b) Is an insertion of four codons possible? Is an insertion of five codons possible? Explain why or why not in each case
A one hundred ml vessel is filled with water separated in equal parts by a semipermeable membrane. The molecular weight cut off of the membrane is 100g/mol.

Within the two groups define by the bone mass, smaller skeletons have bones with evidence of epiphyseal plates, but larger bones have only a thin line where the epiphyseal plates should be. Give the age group and gender of the individuals in this fin..
Aphids can reproduce sexually and asexually. Females reproduce by themselves and give birth to live females in summer. They also reproduce sexually and lay eggs that survive in summer and eggs that survive in the winter and hatch in the spring.
A geneticist makes a cross between two homozygous strains of maize with three different mutations. Compute the map distance between gene pair.
Determine the final guaiacol concentrationg of the following enzyme reaction solutions listed in the table below. Keep in mind that each reaction solution has a total volume of 2000 microliters.
The gene has 32 exons. Removal of exons 3-5 should alter the reading frame and produce a protein with an early stop codon. How might removal of three exons lead to a stop codon that occurs in exon 6 instead of in exon 32?
A drug 2,4-dinitrophenol can get into mitochondria, and carry portons from the intermembrane space, and into the matrix. Determine the effect of DNP on the ATP synthesis in the presence of oxygen?
