Cytokinins are defined as compounds that have biological activities similar to those of trans-zeatin. These activities include the ability to do the following:

Induce cell division in callus cells in the presence of an auxin

Promote bud or root formation from callus cultures when in the appropriate molar ratios to auxin

Delay senescence of leaves

Promote expansion of dicot cotyledons

Constitutively active Ras proteins (RasD) 

Replacement of the normal glycine 12 with any other amino acid (except proline) blocks the functional binding of GAP proteins and in essence “locks” Ras in the active GTP-bound state.

Splice sites are directional in nature. 5’ splice site -the left, or donor, site and the 3’ splice site - right, or acceptor, site
