Answer: Cytoskeleton and cytoplasm
The cytoskeleton is a network of microfilaments that provide structure and support for the cell. You can think of them as the pillars/columns that hold up a house.
The cytoplasm is the aqueous fluid that fills the inside of the cell. This fluid is very important for giving a cell is shape/support. If the cytoplasm was drained out of a cell its shape would collapse like a water balloon losing its water.
Telomerase is involved in adding DNA to the end of the lagging strand.
At the ends of linear chromosomes (telomeres), telomerase uses its built-in RNA template to extend the parent DNA template near the end of the lagging strand, providing room for an RNA primer so that lagging strand synthesis can be completed to the end of the chromosome
I believe you mean legs. If you do, the answer you are looking for is: All spiders have eight legs. They also have two small appendages at the front that are modified legs; these are called pedipalps.
