Protein Synthesis Exam Questions and
Answers
'A' is transcription and 'B' is translation. - ✅✅DNA is the molecule of heredity
that contains instructions to build proteins. In 1958, Francis Crick described the
central dogma of molecular biology explaining the process of gene expression.
What do A and B represent in the image?
DNA has no hydroxyl group on the second carbon. - ✅✅You can observe the
main differences between DNA and RNA. Which statement is true?
C - ✅✅The mRNA strand is synthesized in the 5' to 3' direction. The circles in
the image indicate the chemical group to which the next base is attached. Which
image has the circle in the correct position?
The position of a carbon atom in the sugar backbone - ✅✅DNA and mRNA
synthesis proceeds in the 5' to 3' direction. What do 5' and 3' refer to?
P - ✅✅Protein synthesis is performed by an RNA-protein complex called the
ribosome. As you can see in the image, a ribosome is composed of 3 sites called E,
P, and A. To which site does tRNA add its amino acid to the polypeptide chain
Ribosomes, 2 - ✅✅Where do eukaryotic cells synthesize proteins and which
number represents this organelle in the image?
Codon - ✅✅What is the name of each sequence of three nitrogen- containing
bases of RNA that codes for one amino acid?
, The personnel, the experiment, and the environment - ✅✅The biosafety
cabinet is important for physical containment. In this lab we will use a biosafety
cabinet class II. Who or what does a level II biosafety cabinet protect?
5'-AGU - ✅✅The tRNA shown in the diagram will be able to form a base-pair
interaction with which mRNA?
5'-AGU - ✅✅Three types of RNA cooperate to perform translations
NA?
tRNA, mRNA, rRNA - ✅✅Three types of RNA cooperate to perform translation.
A: Read codons and deliver the amino acids.
B: Carry the genetic information from DNA.
C: Catalyze the assembly of polypeptide chains.
Which type of RNA matches the A, B, and C descriptions, respectively?
Bottom - ✅✅Have a look at this simplified depiction of a DNA strand using the
VIEW IMAGE button. Which strand is the template strand?
5' - AUU ACA AUG GGG GUG CAC GAA UGU CCU - 3' - ✅✅Which is the correct
mRNA sequence resulting from the EPO gene transcription process?
MGVHECP - ✅✅What is the correct amino acid translated from the resulting
mRNA.
