Why are uncompetitive and mixed inhibitors generally considered to be more effective in vivo than competitive inhibitors?

In competitive inhibition, the substrate and inhibitor cannot bind to the enzyme at the same time.the substrate and inhibitor compete for access to the enzyme's active site. In vivo, substrate...

If the amount of DNA in a cell at G1 of the cell is 10 picograms (pg); what will the amount of DNA in that cell be at G2 phase of the cell cycle? Explain why?

12During the second gap phase, or G_22​start subscript, 2, end subscript phase, the cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis. G_22...

Four main differences between the meiotic and mitotic cell division.

Mitosis gives two nuclei, and hence two cells, while meiosis gives four.Mitosis gives identical cells to each other and to the mother cell, while meiosis leads to genetic variation due...

If the quantity of DNA in a cell at G1 of the cell cycle is 5 picograms. What will the quantity of DNA in that cell be at G2 phase of the cell cycle? Give a reason

Meiotic products of the somatic cell have 5 picograms of DNA it means haploid cell content is 5 picograms.Thus the somatic cell is diploid in nature so it will contain...

What are reversible and irreversible HDAC inhibitors? How does HDAC inhibitor selectively inhibits the cancer cell and not the normal cell?

Epigenic modifications, mainly DNA methylation and acetylation, are recognized as the main mechanisms contributing to the malignant phenotype. Acetylation and deacetylation are catalyzed by specific enzymes, histone acetyltransferases (HATs) and...
