The correct answer is a - GTCCAATGC
According to base pairing rules, in DNA G will always pair with C and A will always pair with T.
These letters represent nucleotides. Nucleotides are the building blocks of nucleic acids namely DNA and RNA.
A denotes the nucleotide called Adenine
C denotes the nucleotide called Cytosine
G denotes the nucleotide called Guanine
T denotes the nucleotide called Thymine.
In RNA, there is slight difference in base pairing. Since RNA never has Thymine in its structure, the thymine has been replaced with Uracil. Therefore in RNA, Adenine will pair with Uracil.
<h3>Adverse effects of covering the land with concrete and asphalt is Natural resources are depleted.</h3>

Generally, a small difference in blood pressure readings between arms isn't a health concern. However, a difference of more than 10 millimeters of mercury (mm Hg) for either your top number (systolic pressure) or bottom number (diastolic) may be a sign of blocked arteries in the arms, diabetes or other health problem
.A significant difference in the pressure recorded in the right and left arms can signal circulatory problems that may lead to stroke, peripheral artery disease, or other cardiovascular problems.
