Compare and contrast two mechanisms for transcriptional termination in bacteria.

(rho)p-dependent termination: requires rut (rho utilization site), rho protein binds, moves towards 3' end, DNA encodes GC rich for stem loop, RNApoly pauses, rho protein catches up and separates RNA-DNA hybrid

(rho)p-independent termination: Uracil-rich sequence causes RNApoly to pause, stabilized by NusA near open complex RNA exit, UA bonds to weak to hold, DNA-RNA hybrid dissociates AKA intrinsic termination

<h2>Cycads and Palm</h2>

Explanation:

The resemblance between cycads and palm trees is only superficial

  • Cycads are basically woody plants which have roots, a stem, leaves and reproductive structures known as cones
  • The main roots of cycads are thickened and fleshy and as they may have storage capacities they are often termed tuberous
  • Along with the fleshy stem they may have contractile properties which serve to regulate the level of the stem in the ground
  • Specialized, upright-growing, branched roots, known as coralloid roots, are also produced by all species of Cycads
  • The stems of cycads may be completely subterranean or emerge from the ground and be trunk-like
  • The leaves of most cycads are once-divided (pinnate) and often develop an attractive palm-like crown
  • Palm trees are a type of evergreen plant belonging to the Arecaceae family of plants
  • Palm trees have branch-less stems and large evergreen leaves
  • Generally, leaves of palm trees are either pinnate (feather-like leaves) or palmate (fan-like fronds)
  • Another way to identify the type of palm tree is by the trunk shape, some of the tallest species of palm trees have long slender single trunks and dwarf varieties have usually short fat palm trunks
  • Some smaller palm tree species may have clustered trunks with 3 or 4 short trunks growing together
  • There are also some dwarf palm trees that just have bushy pinnate fronds growing out the ground and don’t have any trunk at all
