NADH and FADH2 are both electron carriers that donate their electrons to the electron transport chain. The electrons ultimately reduce O2 to water in the final step of electron transport. However, the amount of ATP made by electrons from an NADH molecule is greater than the amount made by electrons […]

Two autosomal genes control horn color in dragons. Pure-breeding gold-horned dragons were mated to pure-breeding silver-horned dragons. All of the F1 were gold. The F1 were intermated and the F2 generation consisted of 147 gold, 16 silver and 100 bronze. A) what’s the genetically based phenotypic ratio that should be […]

Case Study- Acute Renal Injury and Chronic Kidney Disease Will is a 68-year-old male with a history of hypertension. Eight months ago, he started regular dialysis therapy for ESRD. Before that, his physician was closely monitoring his condition because he had polyuria and nocturia. Soon it became difficult to manage […]

Sequencing several genomes, including that of the zebra fish, has revealed a number of receptors and transporters. In one case, positional cloning of the zebra fish golden gene identified a putative cation exchange protein called SLC24A5. When the golden gene is mutated, the normally black horizontal stripes are pale or […]
