Cell_nucleus

The Nucleus: contains the genes of the cell. Its size is about 5um. in diameter. It is surrounded by a lipid bilayer perforated with pores. There is a 20-40 nm. space between the layers of the membrane. Chromosomes are rod shaped structures containing DNA and protein. Chromosomes are usually broken down into chromatin. The Nucleolus is also found in the nucleus. It produces ribosomes at a rate of 10,000 / min. The nucleus controls the cell’s functioning through the production of m-RNA.

Here are some left brain activities:

Left-brain students feel engaged during your lesson:

Write an outline of the lesson on the board. Students with left-brain strengths appreciate sequence.

Go ahead and lecture! These students love to listen to an expert and take notes.

Discuss vocabulary words. Make a crossword puzzle on the Nucleus and its parts.

Discuss the big concepts involved in the function of the nucleus, how each part is formed and used, and so on.

If it’s left-brained, present it as a speech, perhaps with an occasional visual.

If it’s right-brained, present it as a slide-show.

If it’s both, perhaps you could do both…?

By the way, Tony S., your left side of brain controls your right side of body.
