Answer #1

There are 3 classes of homeotic genes A, B and C for flower development. That is formation of sepals, petals, stamen and carpel from flower mesistem.

APETALA 2 belongs to class A gene. It produces a transcription factor and responsible for sepal and petal formation from whorls 1 and whorls 2.

So mutatant APETALA 2 will allow AGAMOUS expression and will lead to the formation of carpel and stamen instead of sepals and petals. Actually presence of class A gene (APETALA 2) prevents expression of class C genes ( AGAMOUS) in the first two whorls.

How can one experimentally determine that the wildtype and mutant of a bacteria internalize the cell by two different pathways? The bacteria being studied is Arcanobacterium haemolyticum which is a gram positive, non motile rod that causes pharyngitis and other imfections. This bacteria expresses an unusual phospholipase which is proposed to promote bacterial pathogenesis. The wildtype is the normal strain and the mutant has had the pld gene removed. What experiment with controls can be set up to determine that...
