Which of the following is not true of histone tails? Group of answer choices They have enzymatic properties that can covalently modify DNA. They are the target of numerous chemical modifications. They experience changes in net charge, shape and other properties of histones in response to modifications. They are recognized by certain enzymes.

Option A, They have enzymatic properties that can covalently modify DNA.

Explanation:

Histones have very basic nature and possess no enzymatic properties. However, any modification of DNA is carried out after the end of translation process with the help of enzymes on the N –terminal tails through processes such methylation, acetylation, citrullination, phosphorylation.  

There are several Histone-modifying enzymes in the human genome that interact with the non-histone proteins to form functional complexes

Hence, option A is correct

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
