Question: William Astbury discovered that the x-ray diffraction pattern of wool shows a repeating structural unit spaced about 5.2 Å along the length of the wool fiber. When he steamed and stretched the wool, the x-ray pattern showed a new repeating structural unit at a spacing of 7.0 Å. Steaming and stretching the wool and then letting it shrink gave an x-ray pattern consistent with the original spacing of about 5.2 Å. Although these observations provided clues to the molecular structure of wool, Astbury was unable to interpret them at the time. Given our current understanding of the structure of wool, interpret Astubury's observations. Explain why wool sweaters or socks will shrink when washed in hot water or heated in a dryer whereas silk does not shrink under the same conditions.

Think about another population of the same flower, but in this case there is another incompletely dominant blue allele in addition to red and white alleles.
Suppose that a dihybrid cross is made in which gene loci are autosomal, independently assorting, and incompletely dominant.
A student argued that this is too time-consuming as the complete amino acid sequence should be determined in order to create the probe. Does the student have a valid argument? Why or why not with reason.
A cell biologist cautiously measured the quantity of DNA in grasshopper cells growing in cell culture. Cells examined throughout the G2 phase of the cell cycle contained 200 units of DNA. What would be the quantity of DNA at G1 of the cell cycle in o..
An enzyme and its substrate are combined in a test tube but no product is formed. Another molecule is added to the tube, and now the product is formed at the normal rate. Give 2 reasons.what type of inhibition is working on the substrate.

The concept of vitalism is based on the belief in a life force outside the jurisdiction of physical and chemical laws. According to this belief, organic compounds are able to arise only within living organisms. Which did the most to refute the concep..
