Question

diploid cell contain 2n=14 chromosome and amounts of DNA is 10 pico gram before s-phase what will be no of chromosome amount of DNA in prophase-1and metaphase-1, anaphase-1, prophase-2, metaphase-2, anaphase-2at the each pole of anaphase-1 and anaphase-2 ​

Answer 1

Explanation:

2n =14

n=7

in G1 phase DNA amount is 10 pg

so in in s phase = 2×10 =20 pg

in G2 phase =20pg

in prophase 1=20pg

in metaphase 1=20pg

in anaphase 1=20pg in total in each cell =10pg(in each pole)

in telephone 1= 10pg each cell

in prophase 2 =10pg

in metaphase 2=10pg

in anaphase 2= 10pg in total cell ,in each cell =5pg (at each pole)

in telephone 2=5pg

(pg = Pico grams) (and pg is the unit of amount of DNA)
