AND CORRECT DETAILED ANSWERS (VERIFIED ANSWERS) |ALREADY
GRADED A+||BRAND NEW VERSION!!
What constitutes a "complete medium"? - Correct Answer-It has all the necessary
essential amino acids.
Describe the process of experiments in metabolic defects in Neurospora? - Correct
Answer--Neurospora cells were placed in a complete medium and the subjected
to X-rays
-the surviving cells formed colonies
-Cell were then placed in a minimal medium and nutritional mutants were
identified
-nutritional mutants were placed in vials with a variety of media (different amino
acids)
-each vial was observed for growth
What is Walter Sutton discover? - Correct Answer-He studied grass hoppers and
saw 11 organized chromosomes identical in size that separated into gametes.
What is metabolism? - Correct Answer-It is the totality of an organisms chemical
reactions.
What is a metabolic pathway? - Correct Answer--begins with a specific molecule
and ends with a product
-each step is catalyzed by a specific enzyme

What was the major discovery made in metabolism research? - Correct Answer-
Archibald Garrod discovered that afflicted individuals lacked the enzyme
necessary to break down alkapton. This was called an "inborn error of
metabolism".
An excess of alkapton in urine produced a BLANK. - Correct Answer-Discoloration
Experiments in BLANK studied metabolism and amino acid biosynthesis. - Correct
Answer-Neurospora (commonly found as mold on bread)
What is Chargaff's rules? - Correct Answer-A=T and C=G
What did Chargaff's discovery determine? - Correct Answer-The discovery was one
of many that helped determine DNA was the source of genetic material.
BLANK and BLANK used a X-ray crystallography to study molecular structure. -
Correct Answer-Maurice Wilkins and Rosalind Frankin. Franklin produced a picture
of the DNA molecule using this technique.
What was the most important discovery in biology in the past 50+ years? - Correct
Answer-Watson and Cricks idea that DNA is organized as a double helix.
"We stand on the shoulders of others"

What is the Central Dogma? - Correct Answer-
What does the use of RNA as an intermediate provide in the central dogma? -
Correct Answer--protection of DNA
-ability to produce more copies of polypeptides
BLANK determine the sequences of base in mRNA. - Correct Answer-Genes
BLANK sequences determine amino acids sequence. - Correct Answer-mRNA
What are the two outcomes of codons in mRNA? - Correct Answer--translated into
an amino acid
-translated into a stop signal
What is a transgenic or recombinant organism? - Correct Answer-A gene is
transfered from one organism to another and it is expressed as a protein in the
other organism.
How can you take advantage of the universal code? - Correct Answer--using
bacteria to produce insulin
- creating transgenic animals and plants (GFP gene)
-mutate a protein to study the effects
What are the steps to creating transgenic organism? - Correct Answer-1) a gene of
interest is inserted into a recombinant DNA plasmid
