Why does a cell undergo mitosis? How do nerve cells form different types of tissues? Why do multicellular organisms need communication systems? How do plant cells differ from animal cells? Explain why hormones in the bloodstream are able to affect only target cells or organs and not other cells...
Observation 3:Redox regulatory mechanisms of gene expression are relatively well-studied in chloroplasts (e.g. transcription regulation via chloroplast sensor kinase [92]), while for the mitochondria, it is known that redox reagents have certain effects on protein synthesis, although particular mechanism...
However, when resting B cells are activated in vitro, generally only CSR can be observed (Stavnezer, 2011; A. Durandy, unpublished), but the VH region does not undergo SHM. In the in vitro activated B cells, SHM mutations do occur in the switch regions activated by the respective ...
Why do animal cells undergo Meiosis? a. Which part of meiosis is the most similar to mitosis - the first or second division (meiosis I or meiosis II)? b. Why do you think that division is the most similar? Regarding meiosis and mitosis, one d...
Unlike T and B cells, ILCs lack antigen-specific receptors and do not undergo genomic receptor rearrangements or clonal selection. They react to tissue perturbations independent of antigen stimulation, and polarization of their effector functions is a feature that largely arises during their development...
Proteins can undergo unspecific proteolytic digestion if the protein sample is not correctly handled. Proteases released during cell lysis or tissue extraction can cause protein fragmentation, resulting in fragments of lower molecular weights. Some proteins are...
In regulation and emotional affect, such as the prefrontal humans, studies have shown the impact of preadolescent cortex (PFC), amygdala, and hippocampus undergo sig- stress as being particularly critical for adult right amygdala nificant maturation during childhood and adolescence. volumes, with ...
Although spontaneous regeneration after central nervous system (CNS) damage is rare, demyelinated CNS axons can undergo remyelination. Remyelination can be very efficient, especially in experimental models. However, in multiple sclerosis (MS) — the most common demyelinating disease of adulthood — ...
Why do the living cells in the granular layer of the skin not undergo cell division? If brain cells are incapable of cell division, what cells or mechanisms involved in the proliferation of brain cancer cells? Why is cell division important as ...
Where do gamete cells come from? What are the functions of proteins? Do lac genes undergo transcription and if so, why? How is the process of translation and transcription able to make other proteins, using genes from other species? What is the importance of meiosi...
