Bones form when cells called osteoblasts secrete chemicals that cause cartilage to harden. Osteoblasts release a mixture of collagen, a strong fibrous connective tissue, and calcium phosphate, a mineral that hardens the collagen. The process of creating hard bone by combining collagen and calcium phos...
The Chemistry, Physics, and Biology disciplines form the backbone of the knowledge tested on the NEET UG exam. You’ll have three hours to answer 180 multiple-choice questions. An applicant gets 4 points for every correct answer, and for every wrong answer, they lose 1 point. NEET exam boo...
These individual virus particles are the infectious form of a virus outside the host cell. Unlike bacteria (which are about 100 times larger), we cannot see viruses with a light microscope, with the exception of some large virions of the poxvirus family ([link]). The size of a virus is...
This paper presents an account of the nature of stem cells based on the philosophical concept of disposition. It is argued that stem cells can be conceived
This pattern of inheritance does not con-form to the law of independent assortment because the alleles for flower color and pollen shape do not segregate indepen-dently of one another, but tend to stay together during meiosis.Crossing Over Creates New Combinations of Linked Allele... ...
Opioid receptors, a subfamily of G protein-coupled receptors (GPCRs), are key therapeutic targets. In the canonical GPCR activation model, agonist binding is required for receptor–G protein complex formation, while antagonists prevent G protein coupling
Additionally, since thecentral protuberance of the 50S subunit interacts with the headdomain of the 30S subunit to form two intersubunit bridges(B1a and B1b) (Selmer et al., 2006; Korostelev et al., 2006;Schuwirth et al., 2005), it is possible that the 5S rRNA-proteincomplex plays a...
