The question is incomplete as it does not have the options which are:
A) single-stranded complementary tails
B) blunt ends
C) poly-A sequences
D) 5' cap
E) interference
Answer:
A) single stranded complementary tails
Explanation:
Restriction endonuclease is the enzyme which cuts the DNA sequence in the internal sequence.
The endonuclease enzyme can cut the DNA sequence in a way that it can form the cuts with the single-stranded overhangs called sticky ends and without overhangs called blunt ends.
The sticky ends are produced when the enzyme makes cut at the single strand and then makes the cut at between the same base at the nitrogenous base. This type of asymmetrical cut forms the single-stranded overhangs which can form the complementary base pairs easily.
Thus, Option-A is correct.
Answer: Codon
Explanation: A codon is a triplet of nucleotides in an mRNA that codes for specific amino acids. There are 64 possible codons. They are called the genetic codes. Three of these codons (UAA, UAG, UGA) do not code any known amino acid and are thus called termination codons. One of the codons (AUG) signals the beginning of translation and is thus called initiation codon.
