2. t/f. chromosomes are replicated a second time just prior to the start of meiosis ii.

FALSE.

Explanation:

After the first replication in meiosis 1, chromosomes don't replicate the second time in meiosis 11.

There are four phases in meiosis 11 and they are the prophase, metaphase, anaphsse and telophase.

In meiosis 1, chromosomes are replicated. In meiosis 11 the replicated chromosomes are condensed I.e condensation of chromosomes during prophase 1. They chromosomes allign in metaphase 1.

The chromosomes are separated into sister chromatids and move to the opposite poles during anasphae 1 and nuclear envelopes is formed arround the chromosomes in telophase 1 aftter it has been decondensed.

idk why hjggjhjkhj

it marks things for degradation via the proteasome. it alters there celluar location.
