Answer:
c. The harmless bacteria had been transformed.
Explanation:
Fredrick Griffith carried out the first experiment that showed bacteria can get DNA by transformation in 1928.
He used two different strains of the bacteria Streptococcus pneumoniae a)type-III-S or smooth strain-Covered by a protective polysaccharide capsule hence lethal
b) type II-R or rough strain-Lacked the polysaccharide hence non-lethal
In his experiment he observed heat killed Type-III-S strain was not able to kill the mice. However, when its remains was added with rough strain then the blend was able to kill the mice.
When he collected blood from the dead mice it had live strains of both smooth and rough type.
He came to a conclusion that non-lethal type II-R strain was transformed into lethal type II-S strain by a "transforming principle" that was supposed to be the part of dead III-S strain bacteria.

Answer:
d. to map all base pairs in DNA
Answer:
it gives energy.
Explanation:
If a person consumes 14 grams of protein present in the Greek yogurt, it gives high amount of energy because protein is a macromolecule which is needed by the human in large amount in order to maintain health of the body. This protein is broken down by a number of enzymes and converted into amino acids which is used in the growth of the body, formation and repairing of muscles.
The correct answer is A because G and C work together, and T and A work together, except A turns into U when transferring to mRNA.
