When a virus infects a bacterium by
injecting it's DNA and the genome of
the virus is incorporated into the
host cell, this is

In Genetic engineering, DNA ligase is
used for which of the following
act as a probe for locating
cloned genes
to create breaks in DNA in order
for foreign DNA fragments to be
inserted
to seal up nicks created in
recombinant DNA
to ensure that sticky ends of like
DNA fragments do not re-Anneal
An example of a post-transcriptional
modification
tRNA
mRNA
Poly-A tail
RNA Polymerase
Binds to the promoter on DNA to
initiate transcription
tRNA
mRNA
Poly-A Tail
RNA polymerase
Binds to free amino acids in
the cytoplasm
tRNA
mRNA
Poly-A Tail
RNA Polymerase
Travels out of the nucleus and into
the cytoplasm where it serves as a
template for translation
tRNA
mRNA
Poly-A Tail
RNA Polymerase
After eukaryotic transcription takes
place mRNA undergoes several
modifications before leaving the
nucleus to take part in translation
