Producing New Cells Flashcards
What does the nucleus contain
Genetic information(DNA) organised into chromosomes.
What is meant by the chromosome complement of a cell.
It means the number and type of chromosomes it contains.
What is the job of the nucleus.
Controls cells activities including mitosis.
What is replication.
The process by which DNA copies itself.
What happens during mitosis.
Each chromosome is replicated.
What is the name for a replicated chromosome.
Chromatid
What happens in mitosis.
The nucleus of a diploid parent cell divides to produce two diploid nuclei.
What happens to the nucleus in mitosis.
A diploid parent cell divides to produce two diploid nuclei.
What do you daughter cells and parent cells have in common
They are genetically identical.
What are the sequences of mitosis.
Chromosomes is start replicating and becoming visible as pairs of Chromatids. The chromosomes line up at the equator and the chromatids are pulled to the opposite Poles by spindle fibres to form new nuclei.
What happens after mitosis.
The cell cytoplasm splits between the new nuclei to form two daughter cells.
What happens when cells undergo mitosis.
It creates cell division artificially in cell culture.
What does cell culture require.
It requires aseptic techniques, in which growth of other cells such as bacteria is prevented and the culture remains uncontaminated.
What does cell culture require.
It requires an appropriate liquid or solid medium such as nutrient agar or Bros in which the cells can grow and divide.
What factors are controlled in cell culture.
Temperature, pH and oxygen levels.
