Question 1: Alpha Helices are formed by hydrogen bonding between __________ and __________ atoms in the protein backbone?
Ci and Ni+4
C and N
O and H
Oi and Hi+4
Question 2: Addition or removal of amino acids from protein sequences or nucleotides from DNA or RNA sequences is known as?
Insertion
Deletion
Indels
None of the given
Question 3: Beeta-pleated sheets are the examples of __________.
Primary structure
Secondary structure
Tertiary structure
Quaternary structure
Question 4: Which of the following statements about amino acids is correct?
Amino acids are uncharged at neutral pH
Amino acids are classified according to the structures and properties of their side chains
Amino acids in proteins are mainly in the D-configuration
Twenty-four amino acids are commonly used in protein synthesis
Question 5: Amino acids are mostly synthesized from
Fatty acids
Mineral salts
Alpha-ketoglutaric acid
Volatile acids
Question 6: Your lab partner is using BLAST, and his best E-value is 3. This means that
He's found 3 protein in the database that have the same sequence as his protein
The chance that these similarities arose due to chance is one in 10^3
There would be 3 matches that good in a database of this size by chance alone
The match in amino acid sequence is perfect, except for the amino acids at 3 positions.
Question 7: How many proteins does the human body produce?
As per hypothesis of "One gene = one protein" So, there should at least ~20,000
Hypothesis of "One gene = two protein" So, there should at least ~40,000
Hypothesis of "two gene = one protein" So, there should at least 10,000
No relation of gene and protein
Question 9: Translation is the process in which
DNA is formed on DNA template
DNA is formed on RNA template
RNA is formed on DNA template
Protein is formed on RNA template
Question 10: Which of the following is not an ionization techniques in proteins?
Matrix assisted laser desorption ionization
MALDI
Electro spray ionization
X-ray crystallography
