1. During DNA elongation, polymerase enzyme adds new, free nucleotides to the three prime end of the newly forming strand, elongating it in five prime to three prime direction while the telomerase protects the important genes at the end of the chromosome from been deleted as the DNA strand shorten during DNA elongation.
2. During DNA elongation, helicase enzyme separates the double stranded DNA into single strand by melting the hydrogen bond that holds the DNA molecule together thus enabling each strand to be copied while the telomerase acts by preventing the telomere from been deleted during elongation.
Answer: b. one atom transfers an electron to another atom
Explanation:
An ionic bond is also called as the electrovalent bond. It is a type of linkage that is formed by the electrostatic attraction formed between ions of opposite charge in a chemical compound.
These bonds are formed when the valence electrons from one of the atom are transferred to the another atom.
I think the answer is NUCLEUS.
Hope it helps!
