Document Summary
Transformation: the uptake of dna directly from the environment; a natural process in some bacterial species. Avery, macleod, and mccarty identified dna as the cause of transformation in griffith"s experiments. Hershey and chase experimented with viruses that infect bacteria (bacteriophages or phages) used to differentiate the roles of dna and protein. Erwin chargaff showed that the nucleotide composition of dna molecules. Watson and crick made the first models on dna based on rosalind franklin"s images. Phosphodiester bond: the uptake of dna directly from the environment; a natural process in some bacterial species. Two strands of the double helix are made up of long polymers of nucleotides, with each strand is made up of repeating sugar and phosphate units joined by phosphodiester bonds (called the phosphodiester backbone) Base-pairs: the uptake of dna directly from the environment; a natural process in some bacterial species. Adenine goes with thymine has a weak hydrogen bond so replication starts here.
