DNA Genetic Coding and Cell Regulation Is Now Understood to Be

question 52

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 scientist (scientists) who was (were) given credit for first determining the molecule structure of DNA by building a ball-and-stick model is (are)

• A) Avery and Macleod.
• B) Griffith.
• C) Chargaff.
• D) Watson and Crick.
• E) Hershey and Chase.

Definitions:

Average-Fixed-Cost Curve

A graphical representation showing how the average fixed costs of production decrease as output increases, due to spreading fixed costs over a larger number of units.

Total-Cost Curve

A graph that shows the total cost of producing different quantities of a good or service.

Marginal-Cost Curve

A graphical representation that shows how the cost of producing one additional unit of a good varies as the production volume changes.

Average-Fixed-Cost Curve

A graphical representation that shows the fixed costs of production per unit of output declining as the quantity of output increases.
