<span>The embryonic period is the most important phase of development for organ formation. The embryonic period in humans begins at the moment of fertilization and continues until the end of the tenth week of gestation. Rapid growth and differentiation occurs during this period, which produces varied cell types.</span>
A good expression vector for protein expression in coli should have features like an origin of replication, a selectable marker, a promotor, an operator, and a ribosome binding site.
A Ribosome Binding Site (RBS) is a part or segment of the upstream part of a messenger RNA (mRNA) molecule which binds the ribosome to position the message correctly for the initiation of translation.
Selectable marker genes are conditionally dominant genes that confer an ability to grow in the presence of applied selective agents that are normally toxic to cells or inhibitory to growth, such as antibiotics and herbicides.
