Aphenotypically abnormal individual has a phenotypically normal father with an inversion on one copy of chromosome 7 and a normal mother without any changes in chromosome structure. the order of genes along chromosome 7 in the father is as follows:

r t d m centromere p u x z c (normal chromosome 7)
r t d u p centromere m x z c (inverted chromosome 7)

the phenotypically abnormal offspring has a chromosome 7 with the following order of genes:
r t d m centromere p u d t r

with a sketch (complete), explain how the abnormal chromosome was formed. in your answer, explain where the crossover occurred (i. e., between which two genes). also, give any other products that might have been formed as a result of the crossover you described. assume that crossing over does not occur at the centromere.

Cold case files recently began re-investigating an old murder case. the murder took place in the park; a young man, james, was hit over the head with a brick and killed. police suspected the jealous former boyfriend of james' wife, karen. whoever killed james may have washed their hands in a near-by bird bath as detectives found blood in the bird bath. since the murder took place before dna fingerprinting was available, the suspected killer, ronnie, went free. detectives are now reviewing the blood evidence using dna fingerprinting. based on the dna fingerprints of all possible suspects, who is james' killer?

Which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements. which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements. the framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center. because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane. the diverse proteins found in and attached to membranes perform many important functions. the kinky tails of some proteins keep the membrane fluid by preventing the component molecules from packing solidly together. membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.
