DefinitionsThe movement of ocean water is one of the twoprincipal sources of discrepancy between dead reckonedand actual positions of vessels. Water in motion is called acurrent; the direction toward which it moves is called set,and its speed is called drift.
Human RBC precursors are obtained by (i) separating glycophorin A(+) (gly A(+)) cells using a magnetic cell sorting (MACS) technique and by (ii) ex vivo expansion of precursors BFU-E (burst forming unit-erythroid) on methylcellulose semi-solid culture media from mononuclear cells of cord blood.
Nucleic acids are the molecules inside the cell that store and process genetic or hereditary information. The two types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). These macromolecules are called nucleic acids, because they were first found inside the nucleus of the cell. The monomers that make up nucleic acids are called nucleotides. Each nucleotide contains a sugar, a base, and a phosphate group.
