Description:How an X-ray diffraction pattern is created and how the DNA X-ray diffraction pattern can be interpreted to give the dimensions. (DNAi location: Code > Finding the Structure > piece of the puzzle > Franklin's X-ray)Transcript:This is the X-ray crystallograph pattern of DNA obtained by Rosalind Franklin and Raymond Gosling in 1952. It is know as the B-form. It was clearer than the other X-ray patterns because water was included in the DNA sample. Both James Watson and Francis Crick were struck by the simplicity and symmetry of this pattern. The distinctive "X" in this X-ray photo is the telltale pattern of a helix. Because the X-ray pattern is so regular, the dimensions of the helix must also be consistent. For example, the diameter of the helix stays the same..........Keywords:x ray diffraction,x ray crystallography,rosalind franklin dna,diffraction pattern,ray pattern,s college
The acetabulum is the cup-like structure where the femur articulates. The head of the femur is the specific structure which articulates in the acetabulum.
Glucose
Glucose, a small polar solute, uses a membrane transporter (a protein carrier) to cross the plasma membrane via facilitated diffusion. In simple diffusion, small nonpolar and lipid-soluble substances (including gases) diffuse directly through the lipid bilayer.
Answer: To clean the exterior and keypad of the microwave.
Explanation:
It is proper to clean the exterior of the microwave including the keyboard. Although this isn't required to be done daily, Benjy saw his mum do it at the time she decided to clean it (maybe it was stained too) and being a child he picks up the act too.
It is advisable to clean not only the interior of your microwave but the exterior top including the keypad. Cleaning the keypad prevents dirt and dust from staying in them and causing the keypads to get stuck.
I hope this helps
