Question

Which of the following must be the order of the genes on the bacterial chromosomal circle? (A is shown at both ends to represent circularty. Assume that the Hfr picks up all intermediates between any two represented genes.) A. ADCEBFA B. ABCDFEA C. ACDFEBA D. AEFBCDA E. AFBDECA Question 2.8: Which of the following is NOT a key property of hereditary material? A. It must be capable of being copied accurately B. t must encode the information necessary to form proteins and complex structures C. It must occasionally mutate D. t must be able to adapt itself to each of the body's tissues E. It must be accurately transmitted

Explanation / Answer

Hfr 1 . . . D A F
Hfr 2 . . . E B F
Hfr 3 . . . E C D

There were three Hfr which are not shown in the question.

The answer is a.

The sequence of the gene will be

ADCEBFA

As Hfr integrated into the chromosome.

2.8

Answer is C
