Collect 5 examples of palindromic DNA sequences by consulting your teacher. Better try to create a palindromic sequence by following base-pair rules.

Select a palindrome sequence from the following

The restriction enzyme EcoRI recognize following palindrome sequence.

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

Decide the ratio between ester bonds and hydrogen bonds that are broken in each palindromic sequence of DNA when treated with EcoRI during the formation of sticky ends

This figure shows the restriction site of Eco RI. This restriction enzyme recognition site is palindromic and have specified base base pairs. This means that the recognition sites have 5^("|")…….G^(darr)" AATT C"……… 3^("|") 3^("|")……."CTTAA "_(uarr)G.........5^("|")

Match the following terms in Column-I with their descriptions by writing the appropriate letters from Column-II. Column-I A) A molecule used to carry foreign B) A rapid way to amplify DNA C) A way to separate DNA fragments D) Molecular scissors E) A gene sequence from more than one origin Column - II I) Restriction enzymes genes into bacteria II) Recombinant DNA in the laboratory III) PCR based on their size IV) Vector V) Gel electrophoresis

Which of the following statements are true of all t-RNAS ? a) The 5.-end has guanine residue b) They are single chains c) The anticodon loop is identical d) The .3-end base sequence is CCA. Select the correct answer using the codes given below :

If the sequence of one strand of DNA is written as follows: 5-ATGCATGCATGCATGCATGCATGCATGC-3 Write down the sequence of complementary strand in 5 to 4 direction.
