Why do animal cells undergo Meiosis? What types of organisms reproduce by mitosis? Why do they do this? Explain why mitosis can occur in a haploid cell, but meiosis can't. Why do smooth muscles only undergo mitosis cell division?
How do myelin sheaths help neurons? Why is an efferent neuron multipolar? Why do body cells (somatic cells) need to divide and how do they know when to divide? Why can't nerve cells regenerate? How do neurotransmitters communicate with postsynaptic neurons?
describe how cells get energy describe how cells use the genetic code to make proteins define and apply basic principles of human inheritance describe the structure and function of the four basic tissue types in the body describe the basic body plan of the human organism ...
A region in a tissue where stem cells are maintained, includes cells that produce a short-range stem cell maintenance signal and the surrounding region where the signal is able to maintain stem cell identity. Although plants and animals use different signals to maintain stem cells, the maintenance...
The use of phosphoproteomic strategies can be very powerful. By combining these methods with quantitation strategies and highly efficient MS technology the compari- son of proteins and PTMs in different cells, disease stages, treatments etc. is possible. Common quantitative strategies include the ...
How do cells specify their dimen- sions, and how is a certain size (like cell shape) advanta- geous in evolutionary terms? It is clear that many cells tightly maintain their size as they grow and divide using homeostatic mechanisms [63,64]. For instance, some cells commit to division ...
The DNA copying that takes place in a cell during mitosis can be compared to a metaphor of a copying machine, one jam builds up and jams other copies and the machine doesn’t work as effectively. This paper jam is ageing, mitosis slows down and takes longer to produce cells and thus ...
For example, “supracastration” agents were developed once it was understood that ADT could not block all the androgen synthesis in a patient's body despite an obvious drop in serum testosterone level. PCa cells can still get androgen support from an increased synthesis of androgens in the ...
It totally removes the measurement problem, but only if we can explain what interactions do. We can’t yet, but we will one day. That’s why it’s a taboo, and why you haven’t heard much about it. People are terrified of things they don’t understand...
What's the purpose of genes in the cell? Why do we only use some genes in some cells?Question:What's the purpose of genes in the cell? Why do we only use some genes in some cells?Answer and Explanation: On a chromosome, each of the genes has a particula...
