The final steps of DNA synthesis involve the removal and replacement of primers with DNA, and the formation of the final phosphodiester bonds of the backbone which join all the fragments into one unbroken strand of DNA.
True or false?
As a result of DNA replication two DNA molecules come into existence. Why is it not correct to assert that two “new” DNA molecules are created? What is the name given to the process concerning that fact?
"Unlike what happens in DNA replication, where both strands
are copied, only one of the two strands is transcribed into
MRNA. The DNA strand that contains the gene is sometimes
called the sense strand, or coding strand, and the DNA strand
that gets transcribed to give RNA is called the antisense strand,
or noncoding strand. Because the sense strand and the antisense
strand are complementary, and because the DNA antisense
strand and the newly formed RNA strand are also
complementary, the RNA molecule produced during
transcription is a copy of the DNA sense strand... The only
difference is that the RNA molecule has a U everywhere the
DNA sense strand has a T."
Consider the following segment of a DNA sense strand:
(5') CAA-ACT-ACG-GCG-TTG-CAG (3’)
