What bases are Pyrimidines?
Cytosine, Thymine, Uracil
What is it called when a DNA is wrapped around a protein?
A nucleosome.
Splicesomes are?
Enzymes that cut out the introns of DNA and then join together the remaining exons together.
What did Alfred Hershey and Martha Chase contribute?
They did an experiment that showed that infected bacterial cells contained only the radioactive DNA from a virus, suggesting that DNA was the hereditary material, not protein.

Pyrimidines
DNA stands for?
How are nucleotides linked together?
By covalent bonds between the phosphates of one nucleotide and the pentose sugar of the next nucleotide.
What did Oswald Avery, Colin MacLeod, and Maclyn McCarty discover?
