During meiosis, what happens to the homologous chromosomes?
During meiosis, what happens to the homologous chromosomes?
- They undergo DNA replication
- They are separated to opposite poles of the meiotic spindle
- They duplicate into two attached chromatids
- They remain together and whole chromosomes are separated from their partners (correct)
What is the crucial difference between meiosis and mitosis?
What is the crucial difference between meiosis and mitosis?
- In mitosis, each mature gamete receives only one copy of each gene
- In mitosis, the homologous chromosomes are separated to opposite poles of the spindle
- In meiosis, the chromosomes duplicate into two attached chromatids
- In meiosis, the two chromatids making up each chromosome remain together (correct)
What is the purpose of meiosis in germ cells?
What is the purpose of meiosis in germ cells?
- To ensure each mature gamete receives only one copy of each gene (correct)
- To separate the two chromatids of each remaining chromosome
- To duplicate DNA exactly once during a discrete period
- To allow uninterrupted DNA synthesis between cell divisions
