Flashcards in Chapter 1.3 Producing new cells Deck (17):
The nucleus of a cell contains genetic information (DNA) organised into
The chromosome complement of a cell is the
number and type of chromosomes it contains
The chromosome complement of most cells is
A diploid is
a cell containing two sets of chromosomes
The nucleus controls the production of new cells called
Replication is the process by which DNA
During mitosis each
chromosome is replicated
A a replicated chromosome is called a
In mitosis the nucleus of a diploid parent cell
divides to produce two diploid nuclei
Daughter cells are genetically
identical to their parent cell
The first step of mitosis is:
the chromosomes replicating and becoming visible as pairs of chromatids.
The second step of mitosis is:
The chromosomes line up at the equator and their chromatids are pulled to opposite poles by spindle fibers to form two new nuclei.
After mitosis, the cell cytoplasm
splits between the nuew nuclei to from two daughter cells.
Cells can be induced to undergo mitosis and cell division artificially in
Cell culture requires aseptic techniques so that
the growth of other cells such as bacteria is prevented and the culture remains uncontaminated.
Cell culture requires nutrient agars or broths so the cells
can grow and divide.
