Each sticky end of DNA fragment that is obtained by using of EcoRI enzyme contains how many nitrogen bases?

Sticky ends of two DNA strands are joined by the action of enzyme

The sticky ends of a fragmented DNA molecule are made of

The enzyme used to join the DNA fragments is :

The stickiness of DNA ends faciliates the action of which enzyme

Assume that their are 8 types of nitrogen bases are available and 500 types of amino acid are available for protein synthesis, then in genetic code each codon made up by minimum how many nitrogen base :

How are .sticky ends. formed on a DNA strand? Why are they so called?

Assertion: Restriction endonucleases produces overhanging stretches called sticky ends on each DNA strand Reason :Restriction enzymes cut the strand of DNA a little away from the centre of pallindrome sites

When DNA molecule is cut by the same restriction enzyme, the resultant DNA fragments have the same kind of 'sticky-ends' and these can be joined together (end to end) using

How are 'sticky ends' formed on a DNA strand? Why are they so called ?

The sticky ends generated by the action of Eco RI on insert DNA facilitate the action of which enzyme ?
