1. Expand YAC.
a) Yeast artificial chromosome
b) Yards After Catch
c) Yet Another Cleaner
d) None of the above
View Answer
Explanation: They are genetically engineered chromosomes derived from the DNA of the yeast.
2. Which of the following are primary components of YAC?
a) ARS
b) Centromere and Telomere
c) ARS and Telomere
d) ARS, centromere and Telomere
View Answer
Explanation: ARS, centromere and telomere are the three essential component for the chromosome maintenance and stability.
3. Autonomously replicating sequences (ARS) is a characteristics feature of _______
a) cosmid vector
b) phage vector
c) yeast vector
d) none of the above
View Answer
Explanation: An autonomously replicating sequence contains the origin of replication in the yeast genome.
4. Shuttle vector is a vector constructed so that it can propagate in two different host species.
a) True
b) False
View Answer
Explanation: These vectors can be grown in one host and then moved into another without any extra manipulation hence they are named shuttle vectors.
5. Vectors that are hybrid between phage DNA molecule and vector plasmid are known as _____
a) Plasmid vector
b) Cosmid vector
c) Shuttle vector
d) Phage
View Answer
Explanation: Cosmid is basically a plasmid that carries a cos site and DNA sequences are originally from lambda phage.
6. Cosmids can be used to build genomic libraries.
a) True
b) False
View Answer
Explanation: Cosmid vector can carry upto 45 kb whereas plasmids and lambda phage vectors are limited to 25 kb.
