What are reproductive cells called

Reproductive cells are called GAMETES.

By what process is the DNA code duplicated

replication

What is the chemical code that makes up most of the chromosomes

DNA

At the end of mitosis what forms around the chromosome groups

As mitosis winds down and the chromosomes reach their opposite poles of the cell, the poles of the spindle apparatus pull at the cell, elongating it. This elongation signals the nuclear envelopes to reassemble and surround the two clumps of chromosomes. In animal cells, a furrow appears around the cell that pinches it into two. In plant cells, a cell plate forms in the middle as the cell wall divides it into two.

What process of cell division produces an exact replica of the cell

in mitosis telaphase makes the replica of the cell when the whole cell splits

How many chromosomes are in a normal human body

There are 23 pairs of chromosomes in a normal human body which means 46 chromosomes. People with down's syndrome have 47 chromosomes.

During meiosis twin chromosomes split apart and move to the

poles
