An extra chromosomal segment of circular DNA is used to carry gene of interest into the host cell. What is the name given to it ?

Let there be two such mid points C and D. Then from above theorem  AC = 1 /2 AB  and AD = 1 /2 AB  ∴ AC = AD  But this is possible only...

(i) Have origin of replication(Ori) (ii) a selectable marker (iii) at least one recognition site.

Gene therapy would be a better option because it has the potential to completely cure the patient. It is because the correct gene once introduced in the patient, can continue...

Foreign gene is usually ligated to a plasmid vector and introduced in the host. As plasmid replicates and makes multiple copies of itself, so does the foreign gene gets replicated...

After identifying a useful gene in bacteria, following steps should be undertaken (1) Isolation of useful gene using Restriction Endonucleases                      ↓ (2) Transferring...

Functional mRNA of structural genes need not always include all of its exons. This alternate splicing of exons is sex-specific, tissue-specific, and even developmental stage-specific. By such alternate splicing of exons, a...

(c) two extra neutrons and no extra electron

a. Human gene may have intron which bacteria cannot process
