Sequence reasoning

Assertion : Restriction enzymes recongise palindromic sequences. Reason : Palindromic sequences read same in both directions of the two strand.

Assertion : DNA fingerprinting involves identifying differences in specific regions in DNA sequence. Reason : DNA lingerprinting is the basis of paternity testing.

Assertion :- DNA fingerprinting involves identifying differences in some specific regions in DNA called as repetitive DNA sequences. Reason : These sequences show high degree of polymorphism & from the basis of DNA fingerpringing.

Assertion : Each restriction endonuclease funtions by 'inspecting' the length of a DNA sequence Reason:Once it finds its specific recognition sequence, it will bind to the DNA and cut hydrogen bonds

Assertion : DNA fingerprinting involves identifying difference is some specific regions in DNA sequence. Reason: In repetitive DNA sequences , a small stretch of DNA is repeated many times.

Assertion A genetic probe is helpful in the detection of specific DNA sequence. Reason Genetic probe is a radiolabelled cDNA, which has complementary base sequence, to DNA fragment which is to be detected.

Assertion :- The probability of DNA polymorphism would be higher in non-codeing DNA sequences. Reason : Mutations in these seuqences may not have any immediate effect in an individual's reproductive ability.

Assertion: The events of the sexual reproduction though elaborate and complex, follow a regular sequence. Reason: Sexual reproduction is characterised by the fusion (or fertilisation) of the male and female gametes, the formation of zygote and embryogenesis.
