The griffith experiment showed that certain strains of streptococcus bacteria could transform from one strain to another when combined. how did the avery-macleod-mccarty experiment expand on frederick griffith's observations

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.
