BIOL 3110 Exam 1 Solved Papers -
Questions with Complete Solutions
What is Chargaff's rules? - Correct Answers ✅A=T and
C=G
What did Chargaff's discovery determine? - Correct
Answers ✅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 Answers ✅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 Answers ✅Watson and Cricks idea
that DNA is organized as a double helix.
"We stand on the shoulders of others"
What is Walter Sutton discover? - Correct Answers ✅He
studied grass hoppers and saw 11 organized chromosomes
identical in size that separated into gametes.
What is metabolism? - Correct Answers ✅It is the totality
of an organisms chemical reactions.

Questions with Complete Solutions
What is a metabolic pathway? - Correct Answers ✅-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 Answers ✅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
Answers ✅Discoloration
Experiments in BLANK studied metabolism and amino acid
biosynthesis. - Correct Answers ✅Neurospora (commonly
found as mold on bread)
What constitutes a "complete medium"? - Correct Answers
✅It has all the necessary essential amino acids.
Describe the process of experiments in metabolic defects in
Neurospora? - Correct Answers ✅-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
, BIOL 3110 Exam 1 Solved Papers -
Questions with Complete Solutions
-nutritional mutants were placed in vials with a variety of
media (different amino acids)
-each vial was observed for growth
What is the Central Dogma? - Correct Answers ✅
What does the use of RNA as an intermediate provide in the
central dogma? - Correct Answers ✅-protection of DNA
-ability to produce more copies of polypeptides
BLANK determine the sequences of base in mRNA. - Correct
Answers ✅Genes
BLANK sequences determine amino acids sequence. -
Correct Answers ✅mRNA
What are the two outcomes of codons in mRNA? - Correct
Answers ✅-translated into an amino acid
-translated into a stop signal
What is a transgenic or recombinant organism? - Correct
Answers ✅A gene is transfered from one organism to
another and it is expressed as a protein in the other
organism.
