DNA segment cleaved by EcoRI is

If EcoRI cut the ds. DNA fargment at four places, then what is the ratio of number of hydrogen bonds present at those locations before cleavage by EcoRI and number of hydrogen bonds cleaved by EcoRI at those loactions respectievly ?

The ratio between phospho esterbonds and hydrogen bonds that are broken in each palindromic sequence of a DNA, when treated with EcoRI is

The specific DNA sequence recognised by EcoRI is

If a long linear dsDNA having blunt ends having. 5' GAATTC3' 3'CTTAG5' sequences at four places is cleaved by using EcoRI, how many DNA fragments are formed with cohesive ends on both sides

Assertion: DNA segments can be excised by 'molecular scissors' or 'chemical scalpels' that biotechnologists call restriction enzymes Reason: Restriction enzymes are synthesised by microbes as a defence mechanism and are specific endonucleases which can cleave double-stranded DNA.

The ratio between undisturbed and distur-bed H bonds in DNA when it is cut by EcoRI in the target site

Draw the vector DNA segment and foreign DNA segments after the action of EcoRI and label the sticky and produced.
