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However, when resting B cells are activated in vitro, generally only CSR can be observed (Stavnezer, 2011; A. Durandy, unpublished), but the VH region does not undergo SHM.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 ...
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...
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...
Would it ever be possible for human cells to undergo conjugation? Why or why not? Human beings are an example of: a) Archaea. b) None of the above. c) Bacteria. d) Prokarya. With examples, list five kingdoms to which organisms are classified. ...
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...
(Peto et al.Citation1975). Larger animals such as elephants have more cells in their bodies. These cells undergo numerous cell divisions over their long lifespans, which creates additional opportunities for genetic mutations that could potentially lead to cancer. However, these large and/or long-...
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 ...
