Yes
Did Transformation still occur without DNA
No
What molecule is responsible for transformation?
DNA
Even after Avery discovered the transforming factor, why didn’t scientists accept this?
Scientists were still skeptical that DNA was responsible for heredity. They didn’t believe that such a simple molecule could be responsible for heredity.
Why does a virus infect genetic material into a host?
To reproduce
What was the 1st of Chargaffs Rules?
In any double-stranded DNA, the number of guanine units is equal to the number of cytosine units, and the same with Adenine and Thymine.
What was Chargaffs Second Rule?
The relative amount of ATCG varies from one species to another.
If a species has 31% Cytosine, How much of the rest of the bases would it have?
Guanine: 31%
Adenine: 19%
Thymine: 19%
What are the parts of a nucleotide?
A sugar, phosphate group, and nitrogen bases (A, T, C, G).
What base pairs are found in DNA?
A=T, C=G
What bases are pyrimidines?
Cytosine, Thymine, (uracil)
