Bell Work: 1/28/13
• Explain the sequence of DNA to
chromatin, chromatin to chromatids, and
chromatids to chromosomes.
• You may use words, pictures, or both.
• You may use your DNA notes (“How DNA
Works flow chart) or pgs. 134-135 to help.
Bell Work
Discussion
DNA wrapped
around proteins
= chromatin
Chromatin gets
compacted into
structures called
chromatids
Two identical
chromatids = a
chromosome
Objectives:

Describe the relationship among genes,
chromosomes, and inherited traits.
(SPI0707.4.3)

Sequence a series of diagrams that
depict chromosome movement during
plant cell division. (SPI0707.1.4)

Explain to your elbow partner
the job of Interphase and why
it is an important phase of the
cell cycle.

Prophase
01/25/12
Metaphase
01/25/12
Explain to your elbow partner
where the chromatids line up
during Metaphase and why
that is important to cell division.

Anaphase
01/25/12
Explain to your elbow partner
why the chromatids (sisters)
get pulled to opposite sides of
the cell.

DNA is copied
Chromatin becomes
chromatids
chromatids attach and line
up
Chromatids separate and
move
Two new nuclei form; mitosis
complete
Cytoplasm divides into two
new cells
