Need ASAP and will rate ASAP. 28 Which of the following does NOT involve recombination as part of the process? A Formation of an Hfr cel B Infection of a cell by a retrovirus C. Transduction D Epigenetic suppression of a gene E. Lysogenic cycle in lambda phage 29 Of the statements below, which one provides the best evidence that all cels in the same multicellular organism 29. Of the statements below contain the same genes? A All somatic cells contain the same number of chromosomes B. All somatic cells contain the same amount of DNA. C. The C The nucleus fioma denucleated egg and the agg will develop nucieus from a differentiated cell can be transterred to a denucleated egg and the egg will develop nto a complete organism D. All members of the same species possess the same cell types E. The same types of proteins are present in all cells of a given cell ype 30. (3) Which of the proteins listed below would not be expected to be present in all t nucleated cells in a mammal? A A nuclear pore protein B Na+iglucose cotransporter C. ubiqutin D. a protein that is part of the translocation complex in the rER E. a protein forming part of the nuclear lamina 31. Retrotransposons are simlar to retroviruses in that A. Both generate DNA sequences that B. Both have long terminal sequences C. Both encode a transposase D A and B only E. A, B and C beccme integrated into a cell's DNA 32. A researcher wants to k A researcher wants to know what the protein product of a certain gene does What information would she need to know in order to silence the gene using RNAI? A. the base sequence of the gene B. the number of exons in the gene C the sequence of the gene's enhancer D the amino acid sequence of the protein encoded by the gene E. the total length of the coding sections of the gene o that operate in celular The culture media contains ample glucose. What effect would this have on the interaction of the CAP 33. A culture of E·cow has been treated with a toxin that partially denatures 33. A culture of E col has been treated wth a toxin that partialy denatures many enzymes but at a much slower rate, relative to the bacteria's demand for respiration. Celular respiration can proceed, energy. T protein with the lac operon? A CAP will have a conformation that does not permit binding to the lac promoter ll be in a conformation that allows it to bind to the lac promoter B. CAP wi C. CAP will be in a conformation that allows it to bind to the lac operator D. CAP will bind the lac repressor E. CAP will not be present since the conditions stated wi al not permit transcription of the gene encoding CAP 34. A severe mutation has occurred in the promoter for the repressor gene in a lambda phage. Due to this mutation the phage will not be able to A. circularize B. enter into a lysogenic state C. correctly assembly capsid proteins into a viriorn D protect itself from the host celil's restriction enzymes E. produce lysozyme Page 8 of 16

Explanation / Answer

the allele present are ;

C - curved hair ,dominant

C+ -recessive ,straight hair

H -spiraled hair - dominant

h -recessive of spiraled

a/a+ -lack of hair { seen at third locus }

1. phenotype of the female mosquito ;

the phenotype of the female will be curved hair which is a dominant allele ,located at the first locus of the gene .

2. Genotype of the male parent ;

c+/c+ ; h/h ; a/a+ ,

c+ represent the straight hair which is a recessive allele ,a no hair , h ,recessive spiraled hair
