Two students decide to repeat the Hershey and Chase experiment with modifications. They decide to label the nitrogen of the DNA,

rather than the phosphate. They reasoned that every nucleotide has only 1 phosphate, but 2-5 to nitrogens so labeling the nitrogens would provide a stronger signal than labeling the phosphates. Why will this experiment fail to show what Hershey and Chase showed?

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.

What is least likely to be an example of a variation within a species ?
Ket [755]

Answer:

Option D,  Number of limbs

Explanation:

Options for the question

a. Birth weight

b. Hair color

c. Number of offspring

d. Number of limbs

Solution

Variation within a species is caused due to genetic differences governed by varying allele frequencies and duet to environmental factors that somewhere effect the expression of the genetic potentials thereby causing phenotypic variation.  

Number of limbs is a physical characteristics, very unlikely governed by genetic variation. While factors such as hair color (grey, black, white etc.), height (tall, short, medium) etc. are governed by genetic variation as a result of which they have several phenotypic variations.

Hence, option D is correct
