Answer:
20 ( B )
Explanation:
Given data:
a and b are 10 map units apart
b and c are 20 map units apart
a and c = 30 map units apart
<em>condition </em>; Triple heterozygote testcrossed
number of progeny = 1000
<u>Determine the number of double crossover result </u>
P( crossover between a and b ) = 10/100 = 0.1
P( crossover between b and c ) = 20/100 = 0.2
p( double crossover ) = 0.1 * 0.2 = 0.02
hence number of double crossovers = number of progeny * 0.02
= 1000 * 0.02 = 20
Explanation:
DNA makes up the chromosomes which is divided into cells during mitosis. Chromosome and the DNA within are coded to give cells a specialized purpose. These cells are then used to help the organism live and carry out everyday functions.
DNA is given to said organism by the parent(s). Chromosomes are DNA strands condensed into a small package. While the DNA is constantly being reproduced the cells are too. The chromosomes are divided in the mitosis process. Remember the acronym PMAT. Prophase which the cell's nuclear envelope dissolves. Metaphase which the chromosomes line up in the middle of the cell. Anaphase which the spindle fibers attach to the sister chromatids and pull them to each side. Telophase which the nuclear envelope reappears and the cell is ready to split into the daughter cells.

Answer:
The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape.
