A genetic element is foun dto contain several genes and to catalyze its
own movement within and between chromosomes. Inverted 35 inucleotide
repeats are present at the ends of this genetic element. This genetic
element in hepatocytes is incapable of replicating independently. Based on
this description, this genetic element is best categorzied as which of
the following?

a. complex transponson
b. insertion sequence
c. plasmid
e. regulon



  #2

A -many genes

  #3

can u explain why? complex transposon

  #4

i think the q describes the structural features of transposon

many genes - transposon

single gene - insertion sequence


  #5

i too think it is a Transposon. But i dont have the exact answer

  #6

can plasmids replicate independantly?

  #7

yes definitely,,,

  #8

ans C as plasmid carry a variety of genes eg fertility gene gene for antibiotic resistance etc


  #9

plasmid = cannot replicate independently
= prokaryotes have repeating nucleotides at the end
= carrying no.of genes


please confirm

  #10

plasmids need the same enzymes for replication as the chromosomes.......what does this mean ,can they replicate independently.just read it from a site and couldnt follow.
