Answer:
I'm pretty sure the answer is Option D (Recombinant DNA)
Explanation:
The answer that I would've put is not is not an option.
I would've put gel electrophoresis
Answer:
The one treated with DNase and protease
Explanation:
<em>The samples that will transform yellow into purple if RNA is the genetic material are the ones treated with </em><em>DNase </em><em>and </em><em>protease</em><em> respectively.</em>
<u>The treatment of the heat-killed sample of the purple life with DNase will ensure that the DNA in the sample becomes degraded while treatment with protease will ensure that protein is degraded, leaving only the RNA. Thus, the RNA can be taken up by the yellow life form and become transformed into purple if indeed RNA is the genetic material.</u>
The sample treated with RNase cannot transform the yellow life into purple because the RNase catalyzes the degradation of RNA into smaller components.
1-refraction
2-transmission
3-reflection
4-diffraction
<u>Explanation:</u>
Refraction is the bending of a wave when it enters a medium where its speed is different.Refraction is responsible for image formation by lenses and the eye.
Transmission of light is the moving of electromagnetic waves through a material. This transmission can be reduced, or stopped, when light is reflected off the surface or absorbed by the molecules in the material.
Reflection is when light bounces off an object.Light is reflected when there is a mismatch between materials through which the light is travelling.
Diffraction is the slight bending of light. The amount of bending depends on the relative size of the wavelength of light to the size of the opening.
