During DNA replication, the covalent bonding of nucleotides into a new strand of DNA is performed by .a. RNA polymerase b. DNA polymerase c. DNA d. ligase e. primase

Option B) DNA polymerase

Explanation:

During DNA replication, semi-conservative replication for instance:

- a parent double-stranded DNA splits in two.

- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate replication of a newly synthesized strand

- the new strand contains nucleotides that are complimentary abd covalently bonded to free nucleotides present in the parent strand.

Thus, DNA polymerase is the answer

surface modification is a versatile tool and has been widely used in material science and engineering that has significantly facilitated the study and characterization of complex materials. at  matexcel, experienced experts in surface science can offer tailored efforts to meet the specific needs from our clients.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d
