Why does the DNA need to wind up during prophase?

Biology
1 answer:
Advocard [28]3 years ago
7 0

Before mitosis, the cell creates an identical set of its own genetic information – this is called DNA replication. The genetic information is in the DNA of the chromosomes. At the beginning of mitosis the chromosomes wind up into visible objects that can be seen with a light microscope. The chromosomes are now two chromatids joined at the centromere. Since the two chromatids are identical to each other, they are called sister chromatids.

Mitosis happens in all types of dividing cells in the human body except with sperm and ova. The sperm and ova are gametes or sex cells. The gametes are produced by a different division method called meiosis.

<h3>What is the name for underground water sources?</h3>

An aquifer is a water-bearing rock that easily transfers water into wells and springs. The aquifers may be dug into and water pumped out of. The porous rock of the aquifer eventually receives water (recharge) from precipitation.

<h3>What is the source of most groundwater?</h3>

The majority of groundwater comes from rainfall in the form of hail or snow, which is meteoric water. If water from these sources is not lost through evaporation, transpiration, or stream runoff, it may seep into the earth.
