<span>In order to determine the sugar molecule associated with the nucleic acid, we must first determine if the nucleic acid is a deoxyribose nucleic acid (DNA) molecule or a ribonucleic acid (RNA) molecule. We can determine this by looking at the bases in the molecule, as DNA has thymine and RNA has uracil. After the type of molecule is determined, the nature of the sugar is given by the name. DNA has deoxyribose and RNA has ribose</span>
The hypothesis by Coleman was that the product of the ob+ gene was the appetite suppressing hormone. Hence, the homozygous ob/ob mutant are in a position to synthesize that hormone, and its circulating level would be zero. He also hypothesized that the product of the db+ gene was the receptor for the appetite-suppressing hormone. Thus, the homozygous db/db mutant would be able to synthesize the hormone but would not be in a position to respond to it. It would eat excessively and produce large amounts of body fat, which in turn would produce large amounts of appetite-suppressing hormone . In the absence of a receptor, the db/db mutant's hormone level would remain abnormally high.
Coleman's hypothesis were confirmed when the precise functions of the ob+ and db+ genes were determined. The peptide hormone encoded by the ob+ gene was named Leptin.
Answer:
C. levels of specific hormones
Silk worms are an invasive species in the UK. They cover trees and kill them….. silk comes out of their butt and we call it silk thread. Silk thread is silk spun into thread, or silk worm pooo pooooooo
