(1pt) There are four different variations of these monomers (four different nucleotide bases), what are the names of those bases? They are Adenine (A), Thymine (T), Guanine (G), Cytosine (C). 5. (1pt) These bases specifically pair with one other base, known as complementary base pairing.
Lung abnormalities with an increased density - also called opacities - are the most common. A practical approach is to divide these into four patterns: Consolidation; Interstitial; Nodules or masses; Atelectasis; In this article we will focus on this four-pattern approach. At the end we will also discuss diseases that present as areas of decreased density.
