Scientists’ understanding of the role and function of DNA has built up over time. How did the findings from Hershey and Chase’s

bacteriophage experiments likely influence the Meselson-Stahl experiment, and how might Meselson and Stahl’s results help scientists understand how damaged DNA can be inherited by future generations?

Answer:

Hershey & Chase concluded. after the experiment that the genetic material that is passed from virus to the bacteria is not the protein coat but DNA. It proves the DNA is the genetic material and not the protein.

After labelling the Phage DNA and protein, Hershey and Chase performed a series of experiments like infection, blending and centrifugation. Hershey and Chase gave full evidence of the DNA being a genetic material by their experiments. To perform the experiment, Hershey and Chase have taken T-2 bacteriophage (invaders of E.coli bacteria).

Describe two inheritance patterns besides simple dominance
Phantasy [73]

Explanation: All of it is in gamete formation. Meaning, it is going through a gamete formation which also means that pairs of alleles that are for different traits, segregate. They move on independently from one another, never touching.

For your question, It's incomplete dominance which is when cases with one allele isn't complete to be dominant over another allele. It's all got to come together in order for it to become a strong and dominant allele, or else it won't be complete and won't become and do what it has to.

I hope this help you and I hope that I gave you what you wanted/needed for this question.

HELPPP ME PLZZZ IM DUM IKKK
Margarita [4]

Answer:

brown in summer, grey in winter -> camouflage from predators

storing fat during the summer -> gives them extra energy in the winter when there is less food

antlers with forward projections -> allows them to dig in the snow to uncover more food sources, also good for fighting predators

widely spaced hooves -> easily walk on snow and to dig for more food

migrate in herds -> find new area for more food & escape extreme weather, predators, and pesky bugs

PLEASE HELP!! i need help with this for biology i’m desperate please
Vanyuwa [196]

As per the demonstration of Griffith and Avery, it can be concluded that the given experiment finding supports hypothesis III, i.e. genetic material or transforming substance is DNA.

<h3>What is Genetic material?</h3>

Genetic material may be defined as any substance found in the cells of plants, animals, microbial or other origins that hold genetic information and that departs it from one generation to the next.

In 1944, Avery and others concluded that the transforming material was pure DNA, not protein or RNA.

These investigators found that DNA extracted from a virulent strain of the bacterium Pneumococcus genetically transformed an avirulent strain of the organism into a virulent form.

Therefore, as per the demonstration of Griffith and Avery, it can be concluded that the given experiment finding supports hypothesis III, i.e. genetic material or transforming substance is DNA.
