In a polar covalent bond, the bonding pair of electrons in the bond are attracted more strongly to one molecule than the other. This means the electrons are pulled closer to one atom than the other.
In the example of water, the electrons, in the hydrogen-oxygen bond, are more attracted to oxygen and therefore the electrons are drawn closer to the oxygen. This leads to a slightly negative charge on the oxygen and a slightly positive charge on the hydrogen.
The nucleic acid is DNA best conclusion the scientist can make based on the observation
These substances are all mutagens.
<h3>What purposes do mutagens serve?</h3>
Many mutagens are employed to kill cancer cells because they are very harmful to growing cells. Chemotherapy may involve the use of intercalating drugs like daunorubicin and doxorubicin as well as alkylating agents like cyclophosphamide and cisplatin.
<h3>What consequences do mutagens have?</h3>
Additionally, lesions that increase the number of single-stranded regions in the genome may be introduced by mutagens that rapidly degrade DNA, leading to even higher frequencies of recombination.
<h3>How do mutagens cause harm?</h3>
A mutagen is a substance that can permanently alter cells' genetic material, perhaps resulting in heritable genetic harm or cancer.

The inflammation will not occur with tissue that is dead & has no blood supply. The injury brings a decrease in white blood cells. The Mast Cells play a role in releasing histamine which dilate capillaries and bring about hypermia cause increase blood and swelling and redness to the area
The nitrogenous bases placed in between the DNA double helix strands, like rungs on a ladder, are positioned there because of the hydrophobic effect and are stabilized by hydrogen bonding. The stability of DNA also relies on the interactions between the hydrogen bonds between bases, hydrogen bonds between bases and surrounding water, and base interaction between neighboring bases.
Hydrogen bonds are able to stabilize the DNA double helix by pairing up with their complementary base pairs (guanine with cytosine and adenine with thymine)
