En la especie vacuna la falta de cuernos F es dominante sobre la presencia f. Un toro si cuernos se cruza con tres vacas: a) Con las vaca A, que tiene cuernos, se obtienen un ternero sin cuernos. b) Con la vaca B, también con cuernos, se produce un ternero sin cuernos c) Con la vaca C, que no tiene cuernos, se produce un ternero con cuernos. ¿Cuáles son los genotipos del toro y de las tres vacas? ¿Qué descendencia cabe esperar de cada cruzamiento?

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)

Acell in the human nervous system whose primary function is to form myelin and the blood-brain barrier, respond to injury, remove debris, and enhance learning and memory is called a(n) cell.
