Answer:
The options
A. It suggested that DNA is the
"transforming principle."
B. It confirmed that DNA is a double helix composed of two antiparallel strands.
C. It demonstrated that DNA consists of four nucleotides where the proportions of adenine/thymine and cytosine/guanine remain constant.
D. It proved that DNA is
semiconservative replication.
The CORRECT ANSWER IS A.
A. It suggested that DNA is the
"transforming principle."
Explanation:
A. It suggested that DNA is the
"transforming principle."✔
Griffith's experiments proved
that transformation can be seen in
pneumococcus, but gave no proof based on what molecular background the transformation was
WHILE, the Avery MacLeod-McCarty experiments proved that DNA was THE TRANSFORMING PRINCIPLE.
B. It confirmed that DNA is a double helix composed of two antiparallel strands.❌
These findings were established by James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin
C. It demonstrated that DNA consists of four nucleotides where the proportions of adenine/thymine and cytosine/guanine remain constant.❌
The findings was established by Erwin Chargaff.
D. It proved that DNA is semiconservative replication.❌
The findings was established by Matt Meselson and Franklin Stahl.
