Question

How many unpaired nucleotides are present in
each sticky end of DNA fragment if a DNA is cut
with ECORI?​

Answer 1

Explanation:

In this diagram A and B are different palindrome sequences on a DNA strand. Only the restriction enzyme that recognizes site B is present. Explain why only two fragments would be produced. The enzyme would cut only at site B, producing two DNA fragments.

Answer 2

4 unpaired nucleotides are present in each sticky end of DNA fragment if a DNA is cut with ECORI

Explanation:

• There are four unpaired nucleotide sequence which are present in the DNA sequence. These are two adenine  and two thymine nucleotide bases.

• Eco R 1 acts as  a molecular scissor and are known as restriction endonuclease.

• It helps in cutting the DNA at specific places and results in the formation of the sticky end which easily helps in  joining it with another DNA sequence.
