Question

cells that have completed meiosis have ______ compared to cells that have finished dna replication but have not entered meiosis. half the number of chromosomes and 1/4 the amount of dna half the amount of cytoplasm and twice the amount of dna the same number of chromosomes and half the amount of dna half the number of chromosomes and half the amount of dna

Explanation:

• Chromosome number:
• DNA replication occurs before meiosis (in the S - phase of the cell cycle). The cell that has finished DNA replication but not entered meiosis has a diploid chromosome number (\(2n\)).
• Meiosis is a reductional division. After meiosis, the daughter cells have a haploid chromosome number (\(n\)). So, the chromosome number is halved after meiosis.
• DNA amount:
• Let the amount of DNA in a non - replicating diploid cell be \(2C\). After DNA replication (but before meiosis), the amount of DNA is \(4C\) (because DNA doubles during replication).
• After meiosis (a two - step division process: meiosis I and meiosis II), the amount of DNA in each of the four daughter cells is \(C\). So, the amount of DNA in cells that have completed meiosis (\(C\)) is \(\frac{1}{4}\) of the amount of DNA in cells that have finished DNA replication (\(4C\)).

Answer:

half the number of chromosomes and 1/4 the amount of DNA
