Restriction fragment length polymorphism denotes that a
single restriction enzyme produces fragments of different lengths from the same
stretch of genomic DNA of different strains of a species or from different
related species. RFLPs are detected as follows:
i. Large
molecular weight genomic DNA is isolated from several strains or related
species;
ii. The
fragments in these digests are separated through electrophoresis
iii. These
'DNAs are then digested with a selected restriction enzyme
iv. Exposed
to a suitably radio-labelled appropriate DNA probe under conditions favouring
DNA: DNA hybridization
v. The
resulting gel lanes are transferred and fixed to a suitable solid support and
vi. The free
probes are removed
vii. The fragments to which the probe has hybridized are detected by filming them as distinct bands on a suitable photofilm through autoradiography.

There are few statements is given regarding the peptide bond are given
(a) For most peptide bonds the ratio of cis to trans configurations is approximately 1:1000
(b) Peptide bonds formed between Xaa and proline (Xaa is any amino acid) the cis to trans ratio is 1:4
(c) Co and N atoms of the peptide grouping are both in planar sp2 hybridization
(d) All three kinds of bonds (N-Ca, Ca-Co, and the Co-N peptide bond) are single bonds
(e) The peptide bond is estimated to have 40% double bond character
