Answer:
Before cell division must occur, the chromosomes must replicate themselves. Sister chromatids are the two initially identical copies.

go help me on my 3 question please
Wave velocity in common usage refers to speed, although, properly, velocity implies both speed and direction. The velocity of a wave is equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity.
Explanation:
<span>Negatively charged R-groups in the primary structure.
This is because nickel acts as a cation, therefore you would be attracting anions, in this case it would be on the proteins that would be binding to the column. Once they bind to the matrix a was buffer of high salts can elute the proteins.</span>
Regions containing metapopulations are created by the birth and immirgration of organisms to those regions.
<span>In general mutations often occur during nuclear division because each chromosome has to replicate before division (mitosis). During replication your 3 billion nucleotides make copies of themselves leaving one copy in the original cell and another in the sister cell after division. This as you can imagine makes mutations most likely to occur here.
