1) What are 3 tips given to you to help you do well in this course?
pay attention during lectures
take notes during lectures
do not miss class (except emergency)
review notes after lecture
attend all lab/tutorial
ask instructors for help
study hard
2) What are the functions of cell division in multicellular organisms such as
humans?
growth of organisms
repair of damage of tissues
produce genetically identical cells
3) Describe what is meant by "Interphase" in the cell cycle. Describe the
events that occur in each phase.
Interphase consists of G1, S and G2. This is where the cell grows or is
getting ready to divide.
G1 is where the cell makes more proteins so that it grows and
increases it size
S phase is where the cell copies its DNA. The number of DNA is
basically doubled so the cell can divide into two. This is also where the cell
produces more phospholipids which make up the cell membrane.
