Answer:
radioactivity will not be able to tell the difference between the DNA and proteins
Explanation:
It seems that the experiment will fail to show what Hershey and Chase showed because they modify some of the aspects. These modifications will cause changes to the results, the main one being that radioactivity will not be able to tell the difference between the DNA and proteins. This is because Amino Acids are proteins that also contain nitrogen atoms, thus labeling the nitrogen would include all DNA and proteins. This being the main reason why Hershey and Chase decided to label the DNA instead.
Answer:
Photosystem I (PS-I )and photosystem II (PS-II ) are two multi-protein complexes. These complexes contain the pigments used to absorb, harvest and catalyze the photons and light energy in the photosynthetic reactions. The main purpose of photosynthesis reactions to produce high chemical energy compounds.
Photosystem I and II are different from each other because of their absorbing wavelength of light. PS-I absorbs the longer wavelength of light than PS-II.
PS-I plays the major role in the production of high energy carriers ATP and NADPH using light energy (700 nm).
PS-II plays its function in the hydrolysis of water and ATP synthesis using light energy (680 nm).
Answer:
Independent assortment
Explanation:
The law of independent assortment says that genes for different traits or characteristics assort independently from each other during gamete formation. So each contrasting character's pair assort independently and do not show any association with the pair of other characters.
So after gamete formation collectively the gametes have all the possible combinations of alleles because all the genes are assorted independently in gametes.
This independent assortment of traits leads to some new combination of characteristics in the offspring. Therefore the correct answer is independent assortment.
Answer: The hydrogen bonds holding the base pairs together in a DNA molecule are relatively weak compared to other chemical bonds. ... The new nucleotides join together to form the sugar-phosphate backbone of a new strand of DNA. The result is two DNA molecules identical to the original.
