Answer:

Option A, current scientific knowledge

Explanation:

New scientific discoveries are based on the existing/current scientific knowledge. Knowledge/research/new discovery is inevitable and thus it is continuously tested and trialed thereby leading to emergence of new concepts and theories for same existing fact. All the existing scientific concepts and theories can be refined based on the new interventions but discarding an existing theory completely is non viable.  

For example - Scientist found that atom was the smallest unit of matter. With further discoveries in the later layers,  it was found that it is the electron, proton and neutron which is the smallest unit of matter, and  now the current discoveries shows that there are particles even smaller than electron such as meson and thus meson should be considered as smallest unit of matter.

1. Key Concept List the
Ipatiy [6.2K]
<h2>DNA </h2>

Explanation:    

1) Experiment done by Griffith:

  • Griffith used two related strains of bacteria, known as R and S
  • R bacteria were nonvirulent, meaning that they did not cause sickness when injected into a mouse whereas mice injected with live S bacteria developed pneumonia and died
  • Griffith tried injecting mice with heat-killed S bacteria (that is, S bacteria that had been heated to high temperatures, causing the cells to die), the heat-killed S bacteria did not cause disease in mice
  • When harmless R bacteria were combined with harmless heat-killed S bacteria and injected into a mouse, not only did the mouse developed disease and died, but when Griffith took a blood sample from the dead mouse, he found that it contained living S bacteria
  • Griffith concluded that the R-strain bacteria must have taken up what he called a transforming principle from the heat-killed S bacteria, which allowed them to transform into smooth-coated bacteria and become virulent

2) Experiment done by Avery:

  • Avery, McCarty and MacLeod set out to identify Griffith's transforming principle
  • They began with large cultures of heat-killed S cells and, through a long series of biochemical steps progressively purified the transforming principle by washing away, separating out, or enzymatically destroying the other cellular components
  • These results all pointed to DNA as the likely transforming principle but Avery was cautious in interpreting his results
  • He realized that it was still possible that some contaminating substance present in small amounts, not DNA, was the actual transforming principle

3) Experiment done by Hershey and Chase:

  • Hershey and Chase studied bacteriophage, or viruses that attack bacteria
  • The phages they used were simple particles composed of protein and DNA, with the outer structures made of protein and the inner core consisting of DNA
  • Hershey and Chase concluded that DNA, not protein, was injected into host cells and made up the genetic material of the phage
