What's the Term
What do we call DNA when it is not condensed (long and thin)
Chromatin
What do we call the phase in which the cell conducts normal cell functions (phase where the cell spends most of its life)
Interphase
Which cells go through mitosis?
Body cells / somatic cells
How many sister chromatids are there in a normal human cell during prophase?
92
During mitosis, what is responsible for attaching to centromeres and ensuring sister chromatids separate to opposite poles of the cell?
Spindle Fibers
When does the cytoplasm divide to produce two daughter cells?
Cytokinesis
Do random assortment and crossing over occur only in mitosis, meiosis, or in both?
Only meiosis
If a skin cell has 10 pairs of chromosomes, how many chromosomes will there be in a haploid cell?
10
What do we call cells that have a single set of unpaired chromosomes?
Haploid
When do homologous chromosomes separate?
Anaphase I
What type of daughter cells and how many of them are produced after mitosis?
2 diploid cells
If a muscle cell has 14 chromosomes, how many chromosomes will there be in a haploid cell of this species?
7
In meiosis, non-sister chromatids can swap genes. What is this called?
Crossing over / Recombination
When does recombination / crossing over occur?
Prophase I
What type of daughter cells and how many of them are produced after meiosis I and II?
4 haploid cells
The diploid chromosome number in a certain species of fish is 20. How many chromosomes would normally be found in bone cell of this fish?
20
In meiosis, homologous chromosomes randomly move to opposite poles of the cell. Genes are inherited independently of each other. What is this called?
Random / independent assortment
When does random / independent assortment occur?
Metaphase I
In which stage do homologous chromosomes separate during mitosis?
They do not separate during mitosis.
A cell has 40 chromosomes during G1 phase. How many sister chromatids does that cell have during prophase I of meiosis?
80
