Hello,
Microtubules ar edirectely aticipate in meosis because the spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division i.e. mitosis and meiosis. Some of the microtubules attach the poles to the chromosomes by connecting to protein complexes called kinetochores.
Thanking You!

AS Part A Which of the following events occurs during DNA replication? All methylation of the DNA is lost at the first round of replication Methylated DNA is copied in the cytoplasm, and unmethylated DNA is copied in the nucleus Methylation of the DNA is maintained because DNA polymerase directly incorporates methylated nucleotides into the new strand opposite any methylated nucleotides in the template. Methylation of the DNA is maintained because methylation enzymes act at DNA sites where ane strand...
