5' carbon
What was Alfred Hershey and Martha Chase's contribution to the Discovery of DNA
Showed that T4 Bacteriophage injected their DNA into host bacteria cells
What was Rosalind Franklin's contribution to the Discovery of DNA?
Took very good X-ray diffraction images of DNA
The process where RNA is made from the DNA template is called
Transcription
A Nucleotide is made up of
a phosphate group a pentagon-shaped sugar a nitrogenous base
DNA is?
double helix
What makes up the backbone of DNA?
sugar and phosphate
RNA sugars are called ribose and
the 2' carbon does have a hydroxyl group
DNA sugars are called deoxyribose because
the 2' carbon does not have a hydroxyl group
Why must DNA be able to make copies of itself?
to make DNA for new cell. or to grow
what is the main purpose of DNA?
to store genetic information in chromatids
How did Rosalind Franklin contribute to determining the structure of DNA?
x-ray the structure of DNA
Contains Thymine
DNA
Contains deoxyribose
DNA
normally double stranded
DNA
Contains phosphate group
