No. It was an idea that yielded common positive results. “Not a good theory” is biased terminology. New technology can yield new information, but it does not mean that it was not a good theory.
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.
Chromosome is to cactus as gene is to a needle.
Answer is F: Facilitates the movement of particles across the cell membrane.
Types of proteins found in the cell membrane includes channel and carrier proteins, both which are involved in the process of facilitated diffusion where they help facilitate the movement of large or polar molecules across the membrane.
