Which enzyme is used to release $DNA$ from a plant cell?

Given below are two statements :-
Statement-$I$ : Restriction endonucleases recognize specific sequences to cut $\text{DNA}$ known as selectable nucleotide sequences.
Statement-$II$ : Restriction endonucleases cut the $\text{DNA}$ strand a little away from the centre of the palindromic site.
In the light of the above statements,choose the most appropriate answer from the options given below :-

$A$ - Restriction endonucleases are also called 'molecular scissors'.
$R$ - When fragments generated by restriction endonucleases are mixed,they join together due to their sticky ends.

The plasmid used for the construction of the first artificial recombinant $DNA$ molecule was obtained from which microorganism?

Which enzyme is used to join the ends of two strands of nucleic acid?

Which of the following statements are not true regarding restriction endonucleases?
$A$. They are called molecular scissors.
$B$. These are the enzymes responsible for restricting the growth of bacteriophages in $E. coli$.
$C$. They cut the $DNA$ only at the centre of the palindromic sites.
$D$. They remove nucleotides only from the ends of $DNA$ fragments.
$E$. They recognise specific palindromic base-pair sequences.
