Can you show a picture instead so I can see
Explanation:
DNA is composed of large amount of amino acids and have a lot of amide groups .
Therefore , in the acidic or in basic medium , the DNA molecules is either dissociated or dis stabilized via protonation or de protonation .
<u>The double helix structure of the DNA may break or get dis ordered .</u>
But , from the question , In sodium phosphate buffer at pH = 7.0 , is the neutral condition , hence , the DNA remains unchanged , because of the neutral medium .
And in pure water ,
The DNA molecule remains intact as , in pure water , there are no ions .
The symbol might be in one language and the name another. For example Fe is irons symbol. Fe is ferrum, iron in Latin.
The substance that will have the largest temperature change
is Iron (Fe). In order to find out which one would have the largest temperature
change, you will need the specific heat of the substances. The specific heat is
inversely proportional to temperature change. Since Iron has the lowest
specific heat, it now has the highest temperature change.
