During the replication of a bacterial chromosome, DNA synthesis starts from the replication origin site and
moves in bi-directional way
RNA primes are involved
is facilitated by telomerase
moves in one direction of the site
Somatic hybridization is a technique of
natural breeding
natural pollination
artificial pollination
making a hybrid between two somatic cells
The exchange of genetic material, between non-sister chromatids of a bivalent during meiosis-I, is known as
diakinesis
hybridization
crossing-over
both '1' and '2'
Lack of independent assortment of genes A and B in fruit fly Drosophila is due to
repulsion
linkage
crossing over
recombination
In prokaryotes, the genetic material is

circular DNA with histines
linear DNA without histones
circular DNA without histones
The technique involving insertion of a desired gene into the DNA of plasmid vector is known as
dressing
splicing
cloning
drafting
Jumping genes are known as
exon
