DNA Genetic Coding and Cell Regulation Is Now Understood to Be

question 55

Multiple Choice

DNA genetic coding and cell regulation is now understood to be incredibly important to every cell among organisms, and is also associated with viruses. Through the early and mid 1900s, scientists developed new molecular analysis methods that changed the foundations of how we understand "life" to function. Normal health and homeostasis, as well as disease, and natural variations in form and function among organisms are now better understood. Medical and biological applications have increased dramatically with the understanding of DNA molecule structure, and it is helpful to have recognition of the scientists and sequence of events contributing to our understanding.
-The DNA subunits that form the "rungs" joining the two sides of the DNA molecule are formed by

• A) hydrogen bonds between nitrogen base pairs.
• B) covalent bonds between nitrogen base pairs.
• C) phosphodiester bonds between the deoxyribose sugars.
• D) ionic bonds between the phosphate pairs.
