Answer:c. Separated DNA is attached to the cell membrane before the cell divides.
Explanation:
The prokaryotes are single celled organisms. These are simple organisms which reproduce through asexual mode of reproduction that is cell division. They do not posses well define nucleus. Thus the genetic material remain in the cytoplasm of the cell. On cell division the genetic material (DNA) is distributed into halves for development of two daughter cells. Due to lack of nucleus and it's associated membrane the separated DNA get attach to the membrane before the cell actually divides.
Septoplasty is the surgical procedure.
Answer:
Cool dense water sinks to the ocean floor.
Warm water replaces cool surface water.
Wind blowing parallel to the shore causes upwelling of cool water.
The answer is negative inducible and positive repressible.
This is because, since the gene is constitutive, it is always transcribed
unless repressed. It is also structural because it codes for enzymes or proteins
that are non-regulatory. The fact that transcription factors cannot bind to the
promoter means it cannot be transcribed (hence also repressed by the mutation).
