Cellular structures and lifestyles are much diversified. In spite of these differences, the same basic molecular mechanisms govern the lives of both prokaryotes and eukaryotes,<span> the general classes of proteins involved in signal transduction are conserved all over living cell. This is manifested through the re-used of protein receptors, protein kinases,<span> phosphoprotein phosphates, and ion channel receptors.</span></span>

Eukaryotic cells and prokaryotic cells are distant living things as they have differences even on the cellular level (i.e. the presence of a nuclear membrane, rRNA differences). Although even with these differences, the molecular biology especially for cellular metabolism and signaling pathways are conserved. One of the more common signaling pathway that is seen in both prokaryotes and eukaryotes is the G-protein pathway which involves a seven pass or serpentine protein with an intrinsic GTPase activity (hence the name) which then signal either the production of cAMP or IP3/DAG wherein these second messengers will activate certain protein kinases that will phosphorylate specific proteins and enzymes and regulate cells’ function.<span> </span>

e-lub [12.9K]
It would be: Rr × Rr
Result of cross would be: 1RR, 2Rr, 1rr

So, it's genotypic ratio = 1:2:1
Phenotypic ratio = 3:1

What are the characteristics that biologists use to group organisms into vertebrate clades?
Dima020 [189]
A clade is a group of organisms that includes an ancestor and all of its descendants. Clades are based on cladistics. This is a method of comparing traits in related species to determine ancestor-descendant relationships. Clades are represented by cladograms, like the one in Figure below.
