Describe the experiments and explain the evidence that proved
that (a) DNA is the hereditary material and that (b) DNA replicates
in a semi-conservative manner (the process of DNA replication).
Describe the experiments that revealed the structure of the
genetic material. If a sample of DNA contains 8% adenine (A), then
what are the pwecentage of thymine (T), cytosine(C), and
guanine(G).?
Describe the evidence for the fact that DNA is the genetic
material and the sequence of events leading from the sequence of
nucleotides of DNA to the sequence of amino acids in proteins and
their secretion. Include in your answer:
a. the early evidence for the location of genes on chromosomes,
the first evidence that DNA was the genetic material, and that
genes determined the structure of proteins
b. a description of the mechanisms and structures involved in of
transcription...
Explain why DNA is the ideal genetic material. That is, explain
how DNA uniquely fulfills these properties of the genetic
material:
Stores information securely
Is replicated accurately
Genetic information can be used
Genetic variability occurs so that species can evolve
The Meselson-Stahl experiment proved that DNA undergoes
semiconservative replication in E.coli.
a. Explain conservative, semiconservative and dispersive
replication. Also, if A new strain of Alien bacteria has just been
discovered. Their genetic material is very similar to DNA, however
it undergoes dispersive replication. What would be observed in the
Meselson-Stahl experiment with the Alien DNA?
Explain and describe the key differences
between these two sets of experiments:
Sets of Experiments I: HCV Status
Experiments
In the first set of experiments, examine the blood samples of
individuals with known HCV status. There are three groups of
individuals in this experimental set: (1) individuals with chronic
hepatitis C (this includes patients known to have chronic hepatitis
C or blood donors who are known to have passed HCV onto
recipients); (2) individuals with acute hepatitis C infections or...
Q2. DNA is the genetic material in most organisms. Describe the
unique characteristics that justify that DNA is the most suited
genetic material compared to RNA and protein. (5 points)
How does “The Central Dogma of Genetics” decipher the linear
sequence relationships among DNA, RNA, and polypeptide.
