Collect five examples of palindromic DNA sequences by consulting your teacher. Better try to create a palindromic sequence by following base-pair rules.

Identify the palindromic sequence in the following

Which one of the following can give a complimentary and palindromic sequence ?

Which of the following DNA sequence qualifies to be designted as a palindrome ?

Explain palindromic nucleotide sequence with the help of a suitable example.

_____is considered as a megaproject for determining sequency of base pairs in DNA.

Which of the following statements does not hold true for restriction enzyme? (a) It recongnises a palindromic nucleotide sequence (b) It is an endonuclease. (c) It is isolated from viruses (d) It produces the same kind of sticky ends in different DNA molecules

Read the given statements and select the correct option, Statement 1 : Restriction endonuclease enzymes recognise a specific palindromic nucleotide sequence in the DNA Statement 2: Restriction endonuclease enzymes are called as molecular scissors or biological scissors.

Which one of the following palindromic base sequences in DNA can be easily cut at about the middle by some particular restriction enzyme ?

Which of the following statements are correct ? (i) Restriction enzymes cut the strand of DNA a little away from the centre of the palindrome site, but between the same two bases on the opposite strands. (ii) Hind ll always cuts DNA molecules at a particular point by reconginisng a specific sequence of six base pairs. (iii) Separated DNA fragments cannot be visualised without staining on an agarose gel electrophoresis. (iv) 'Ori' is the sequence responsible for controlling the copy number. (v) DNA is a positively charged molecule.

The base sequence in one of the strands of DNA is TAGCATGAT. (i) Give the base sequence of the complementary strand. (ii) How are these base pairs held together in a DNA molecule? (iii) Explain the base complementarity rule. Give the name of the scientist who framed this rule?
