Answer:
Myosin
Explanation:
Myosin are the major components of both muscle and non muscle cells in striated muscles which is responsible for contraction or movement that convert chemical energy (ATP) into mechanical work thereby generating force and movement.
During cellular movement , myosin filament will be the ones that are responsible for attaching and pulling the other filaments along because Myosin binds to actin at a binding site on the globular actin protein,it also have ATP binding sites which hydrolyses ADP to ATP , ATP binding causes myosin to release actin, which make actin and myosin to detach from each other thereby causing attachment and contraction of other filaments
Answer:scyphozoa
Explanation:cniderians are aquatic animals.they have radial symmetry, that is they can be divided into two halves through any plane.
Cniderians may have nematocyst,which are stinging cells.
They have two forms,which are polyp and Medusa .
There are four classes of cniderians;hydrozoa, scyphozoa,cubozoa and anthozoa.
Scyphozoa are predominantly medusa,which is umbrella shaped.they are jelly fishes.
They have four or eight oral arms.
They possess four gonads and four gastric pouches .an example is the Aurelia.
Answer:
Just as helicase is responsible for unwinding the DNA strand, DNA polymerase is responsible for replicating the strand once it unwinds and separates. DNA is made up of a sugar-phosphate ladder and a nucleotide base.
