Question
The Agrobacterium Ti plasmid contains the following elements, except this one: a) virulence genes for transfer of the DNA from bacterium to plant cells b) genes that induce tumor formation c) hormone biosynthesis genes d) genes for the synthesis of unusual amino acids (opine/nopaline) e) genes for bacteriophages Among Alfred Sturtevant's first crosses demonstrating the phenomenon of linkage the following data were obtained after crossing a double-heterozygous female fly (v/v+; r/r+) to a male carrying the recessive alleles, vermilion (v) and rudimentary wings (r): What is the recombination frequency between the two genes? a) 8% The two genes are located on the X chromosome. Should this affect your estimate of the map distance? a) Yes b) No c) Maybe What was the genotype of the female parent? a) v+ r+ /v r b) v+ r/v r+ c) v+ r+ /v+ r+ d) v r /v r e) vv / rrExplanation / Answer
51. In Agrobacterium, which contain Ti or Tumour Inducing plasmid contain all genes listed above except Bacteriophage genes. Option is e. Agrobacterium is naturally transfer DNA from Bacteria to plant, and cause Crowngall Disease
52. Recombination frequency = No. Of Recombinants / Total progeny x 100
= 7+10 / 590 x 100
= 0.028 x 100
= 2.8%. So the Answer is C.
53. No. Because, mapdistance is based on Recombinant frequency and it depends on distance between genes
54. a
