Answer:
The correct answer is B.It was necessary that each of the two phage components, DNA and protein, be identifiable upon recovery at the end of the experiment
Explanation:
Hershey and chase in his experiment lebelled the T₂ bacteriophage with radioactive sulfur and radioactive phosphorus separately. Then they infect E.coli with T₂phage and separated phage from bacteria by centrifugation.
Because DNA contains phosphorus not protein, cells infected with phage containing radioactive phosphorous showed radioactivity bacause DNA enters the cell not protein confirming DNA is the genetic material and radioactive sulfur was found in supernatant.
Answer:
hybernating,putting on a coat,webbed feet, and yes wings
Explanation:
Answer:
The correct answer is - surface, proteins, and sugars.
Explanation:
Adhesins are the appendages present on the surface of the pathogen that help these pathogens to attach to the host cell and surface of the host. Adhesins are the components that are virulence factor these are present in both viruses and bacteria.
The adhesin component is generally made up of mainly of the proteins and sugars which help them to adhere to the cell of the host.
Thus, the correct answer is - surface, proteins, and sugars.
Answer:
phosphorylation
Explanation:
it is converted in a condensation reaction in which a phosphate molecule is added.
As you can see in the table presented below, all of the gametophytes have seeds do not form in an enclosed structure and <span>undergo alternation of generations (marked in purple)
The gingkos were widespread in the distant past, but are now presented with only one species with fan-like leaves, the Gingko Biloba. (green)
The gnetophytes have three genera with very different looking species. One of the most iconic ones being the Welwitschia mirabilis often called the wise man's beard. (blue)
The conifers include redwoods, like sequoias and all, have pines as leaves and produce cones. (brown)</span>
