2. DNA Is best obtained from autopsy from which organ.

a) Liver
b) Kidney
c) Brain
d) Spleen

Update ( 7 December 2011 ) : After discussion with some of the senior professors of Forensic Medicine, who confirmed that the answer key likely considered Spleen as the answer and cited the following reference from  Post mortem technique handbook By Michael T. Sheaff, Deborah J. Hopster. ( Going by the Golden principle : Examiners are always right..I'm revising the answer from Brain to Spleen )

In the spirit of scientific temperament, please go through the 'Contradictory Reference' which points towards Brain Cortex : " With blood samples, a good HMWDNA recovery from all the bodies investigated was obtained during the first week following the death. In each case, the quality and quantity of the DNA were good enough to realize DNA fingerprints with the SLP system (data not shown). In liver samples, only bodies of postmortem ages ranging from 1 to 7 days allowed us to obtain HMWDNA. HMWDNA was extracted from kidney samples up to one month after death, but the yield of DNA decreased rapidly, becoming very low beyond a period of one week. Past this period, we did not succeed in obtaining DNA fingerprints from DNA extracted. The extraction of DNA from lymph nodes was satisfactory up to one week. Over a postmortem period of 7 days, the DNA was degraded and unsuitable for blotting. HMWDNA was purified from spleen samples up to one week after death and the DNA present in heart tissue or in muscle cells was stable up to one month postmortem period, allowing us to perform DNA fingerprinting. Finally, out of all tissues tested, the brain cortex appeared to be the most stable tissue for DNA recovery, even after long postmortem periods."

Study of the laterally extended curved
ridges (Rugae) and the grooves on the anterior
part of the palate.

It is also known as ‘Rugoscopy'
Palates have got various characteristics like placed
high up or low, broad or narrow. peculiarities of
the bony ridges and prominences.

Harrison Allen (1889) suggested the study of palate prints as a
method of identification.

Study of this method is advantageous because —
(1) Prints (ridge pattern) do not change during
(2) It is protected from trauma due to its
(3) It is protected from heat by bucal pad of
fat and tongue.
(4) Even in twins, the pattern of rugosities may
be similar but not identical.

Thomas and Kotze have classi´Čüed palate
prints basing on the characteristic of the rugae as
follows -

(1) Primary rugae — 5 to 10 mm and 10 mm or
(2) Secondary rugae — 3 to 5 mm.
(3) Fragmented rugae — Less than 3 mm.
