B) reads the RNA strand, and adds the complementary nitrogen
bases to make new RNA strand
C) Stretches the DNA polymers to make new DNA strands
D) joins the two DNA fragments
E) reads the DNA strands, and adds the complementary nucleotides
to amen a new DNA strand. Answer: E) reads the DNA strands, and
adds the complementary nucleotides to amen a new DNA strand
◉ Why does the recessive allele disorder, such as color blindness,
that is linked to human sex chromosomes X affect mostly males?
Because, it is more likely that
A) females have a greater probability of inheriting two recessive
alleles than one allele to express the disorder
B) males need only one recessive allele from his father to express the
disorder
C) females have a lesser probability of inheriting one recessive allele
than two alleles to express the disorder
,D) males need two recessive alleles from the father and the mother
to express the disorder
E) males need only one recessive allele from his mother to express
the disorder. Answer: E) males need only one recessive allele from
his mother to express the disorder
