names
Who discovered the shape and structure of DNA
Watson and Crick
twisted ladder shape. DNA formed by two nucleotide strands twisted around each other.
Double helix
the method of DNA replication in which parental strands separate, act as templates, and produce molecules of DNA with one parental DNA strand and none new DNA strand
Semiconservative replication
Who discovered bacterial transformation
Fredrick Griffith
what is the type of RNA that associates with proteins of form ribosomes
Ribosomal RNA
who were able to demonstrate that DNA was transferred from bacteriophages to bacteria
Alfred Hershey and Martha Chase
type of RNA that has long strands of RNA that are formed complementary to one strand of DNA
Messenger RNA
Replication produces one helix made entirely of old DNA and one helix made entirely of new DNA
Conservative
who identified the molecule that transformed the R strain of bacteria into the S strain
Oswald Avery
Smaller segments of RNA that transport amino acids to the ribosome
Transfer RNA
who analyzed the amount of adenine, guanine, thymine, and cytosine in DNA
Erwin Chargaff
A three based code in DNA or mRNA
codon
What theory states DNA replication in which parental and newly synthesized daughter molecules are interspersed in an essentially random fashion
dispersive replication
