Explain why a change in the primary structure of a protein may alter the tertiary structures. Be specific. Explain the difference between primary, secondary, tertiary, and quaternary structures of proteins. How is the primary structure of a protein manufactured? Explain what happens to...
What is the role of cytoplasm in protein synthesis in the body? Describe how siRNA creates cells deficient in a specific type of mRNA/protein. What is dark-field microscopy? Explain its significance to cell biology. Describe a protein phosphatase and its role in cell ...
A pump creates a very high vacuum in the chamber. The sample being scanned serves as one electrode. The probe tip, an incredibly small distance above, serves as the other electrode. The two electrodes can be scanned past one another by a drive that moves in three dimensions. The tunneling...
As electrons move along the electron transport chain, they lose potential energy. How is the energy that is released used by the cell? a. the energy is used to pump electron from the electron transport chain b.the energy is used to pump NAD+ into the cyt ...
Artificial intelligence (AI) can be trained to recognize whether a tissue image contains a tumor. However, exactly how it makes its decision has remained a mystery until now. A team from the Research Center for Protein Diagnostics (PRODI) at Ruhr-Universität Bochum is developing a new approac...
play a role in the development of those somites, but in which way was still unknown. Professor of Mathematical Biology Roeland Merks and researchers at the Amsterdam UMC have now found an explanation. They published their findings iniScience, an interdisciplinary open-access journal of Cell Press....
apparent after 6 h. Such timing do not rule out a contribution of migration to meiotic drive, as has been described very recently21, but there must exist at least in this instance, a separate factor whose contribution can be seen while the spindle is still at the centre of the cell. ...
Examination of splicing silencer activity The splicing silencer activity of the junction sequences was examined in vitro by analyzing splicing of the heterologous intron of the Drosophila melanogaster doublesex (dsx) gene pre-mRNA in HeLa cell nuclear extracts as described before.18,19 To evaluate ...
