Outside the Nucleus

Do Now:

Use your lab handout to answer. A student measures the low power field of view of their microscope to be 6.0 mm.

A: What is the medium power F.O.V.?

B: if about 20 animal cells fit in the medium power field of view, how big is each cell?

medium power fov
Medium power FOV
  • Medium FOV = (low power diameter)(low power objective) / (medium power objective)
  • = (6.0 mm)(4) / (10) = 2.4 mm
how big are the cells
How big are the cells?
  • (Medium FOV) / (# cells) x 1000
  • = 2.4 mm / 20 x 1,000 µm / mm = 120 µm

Label the cell membrane (aka plasma membrane),

nucleus, and nucleolus on your diagram

about those ribosomes
About those ribosomes…
  • Very important function:

RIBOSOMES MAKE PROTEINS!

They can be found in both eukaryotic & prokaryotic cells

steps in protein production
Steps in Protein Production
  • An RNA copy of DNA is made in the nucleus
  • A type of RNA called mRNA moves out of the nucleus into the rough endoplasmic reticulum (RER)
  • Ribosomes attached to the rough ER use the mRNA instructions to build a protein
  • The protein moves to the smooth ER for further processing. The smooth ER houses other chemical reactions too.
