Which of the following is not a mobile DNA element?
Select one:
a. transposon
b. long terminal repeats (LTR)
c. long interspersed elements (LINES)
d. insertion sequence (IS) elements
Hint: it's not d.
Homework Answers
ans LTR is the non mobile dna sequences .
exlanation:
transposons - these are also known as transposable elements .this are dna sequences that can move with in a gemome.. and are known as retrotransposons and dna transposons .
in bactera the mobile elements are IS ELEMENTS and TRANSPOSONS ..so the answer cannot be one and four
mobile elements in vertebrates are LINES and SINES ..therefore we deducted option also
so remaing option 2 that is LTR is the answer .
now to more clarify
LTR-these are repeated sequence of dna found either sides of retro viruses and are used by viruses to insert thier genetic material into host genome

Which of the following statements correctly describes a DNA transposon? Flanking direct repeats are generated when a transposable element inserts into DNA. Transposable elements are mobile DNA sequences. A new copy of a transposable element is introduced at a new site, and the old copy always remains at the original site during replicative transposition. Transposable elements are thought to have played an important role in the evolution of many organisms. All of the above statements correctly describe a DNA transposon....

you have isolated spontaneous mutations in the LEU6 gene of a haploid strain of the yeast S. cerevisiae. Some of your mutations result in a complete loss of LEU6 gene function. You reason that this phenotype may be due to insertion of a mobile DNA element into the gene. To test this idea, you sequence the LEU6 region ion from several of your mutants and compare the DNA to the previously determined sequence for LEU6 in the parental strain. Numerous...

tnpA res tnpR bla Tn3 Consider the complex transposon in the above illustration. Suppose you discover a derivative of this element that replicatively inserts into target DNA but then becomes "stuck" as part of a cointegrate. Your graduate student sequences the respective gene products and finds no change in the primary amino acid sequences of the encoded enzymes. In which locus must the defect lie?

What are SOS gene products? How are they induced? A. SOS proteins (RecA, SSB, uvrABC, etc); nicked DNA binds to the Lac repressor, causing its release and degradation, thereby triggering expression of the SOS genes B. SOS proteins are the heat-shock proteins; the “chi” sequence binds to some transcription factors inducing expression of these genes C. SOS proteins are only transcription factors that activate other genes; DNA damage causes induction of these transcription factors through single-stranded DNA binding proteins D....
