<h2><u>Answer:</u></h2>
The primary stage is prophase. The nucleolus vanishes and the two centrosomes start to frame the mitotic spindle. The axle extends between two inverse shafts f the cell. Next is the metaphase. The centromeres of the chromatid sets adjust at the focal point of the thematic axle.
At that point anaphase, the centromeres will part that isolates the chromatid combine. They are presently called chromosomes. The last stage is the telophase. The chromosomes will at that point frame a string like chromatin and for throb envelope, a nucleolus shows up.
There are no plate boundaries under Florida. The plate movement that caused Pangea to separate is due to convection currents that roll over in the upper zone of the mantle.
Answer:
The correct answer is - 20000, 25,000 genes.
Explanation:
Genes are made by the functional and physical unit of the heredity called DNA. Genes are the precursors or encoded instructions to make a specific protein. Genes can be small or large depending on the DNA bases present in it which can be hundreds to millions in numbers.
According to the Human Genome Project, which found out the total genes present in a human genome between 20000 to 250000 genes approximately.
Thus, the correct answer is - 20000, 25,000 genes.
