A cell replicates its
before it divides to make sure the each new cell has the
set of genetic material. This process
is called
and takes place in the
. The double helix is unwinded by the enzyme DNA
. Another
enzyme,
will attach to the
and lagging strand to work as a signal for where the replication process has to start.
The enzyme DNA
follows the helicase attaching the nucleotides that will make up the new
DNA strand.
Replication always occures in the direction
of the original DNA.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
