phages can range from 50nm to 200nm.This dimension dont favorizied virused to enty intairlly into their host bacteria.Cell wall of bacteria it is composed of peptidoglycan a glicoprotein that it protect bacteria again enviromental stress and agents.For this reason phages have evolved to inject their genome to the host bacteria.
bacteriophage, your welcome everyone cheating on Study Island. C:
Hershey and Chase's experiment used bacteriophage T2, which consists of protein and DNA molecules. They were able to show that only the DNA component of the bacteriophage was responsible for carrying genetic information into the host bacterial cell during infection.
Yes, bacteriophages are viruses that specifically infect bacteria. They target bacterial cells by injecting their genetic material into the bacterial cell and using the host's cellular machinery to replicate.
mmmm not know me,i dum k
The only non-membrane bound organelle found in the cytoplasm of bacteria is ribosome. Ribosomes are responsible for protein synthesis in all living cells, including bacteria.
bacteria only

The scientists Alfred Hershey and Martha Chase conducted a series of experiments at the Carnegie Institute of Washington in 1952, and concluded that the genetic material of a bacteriophage was DNA.
DNA is the genetic material. However, Hershey-Chase also stated that some little sulfur containing material also entered the bacterial cell. Looking at these two conclusions, Hershey-Chase could not reach a definite conclusion as to whether DNA or Protein contains the genetic material. The conclusion came from Watson-Crick who stated that the sulfur containing material could have entered the cell due to the fact that DNA replication and subsequently translation of the mRNA leads to the synthesis of sulfur containing protein which were found in the bacterial cell.
Martha Chase, along with Alfred Hershey, conducted experiments in the early 1950s that demonstrated DNA is the genetic material of viruses. Their work with the T2 bacteriophage, a virus that infects bacteria, showed that only the DNA from the virus, not its protein coat, was necessary for the infection of bacteria. This pivotal discovery provided strong evidence for the role of DNA in heredity and laid the groundwork for molecular biology.
Protein channels allow the cell membrane to transfer large molecules across it. Remember, diffusion only occurs with small molecules. Protein channels are a necessity to transfer larger molecules.
No. Prokaryotes have no need of protein modification and the ability to ship proteins out of the only cell they are.

No, of course not. Only plants,some bacteria and algae are photosynthetic
