Answer: yes

Explanation: DNA is double stranded helix structure that is made up of a phosphate group, a Nitrogenous base which include the purine and pyrimidime and a 5 carbon deoxyribose sugar. Between the strand is an hydrogen bond that hold them together

DNA replication occur by the unwinding of this double helix strand and the breaking of the hydrogen bond by the enzyme helicase.

Answer:

The double-helix shape allows for DNA replication and protein synthesis to occur. In these processes, the twisted DNA unwinds and opens to allow a copy of the DNA to be made. ... As the new strands form, bases are paired together until two double-helix DNA molecules are formed from a single double-helix DNA molecule.

Answer:

The correct answer is RNA polymerase does not require a primer to add new nucleotides.

Explanation:

RNA polymerase is an important enzyme of transcription process that deals with the formation of mRNA from DNA. unlike DNA replication, transcription process does not require any RNA primer to carry out the synthesis of mRNA in 5'→3" direction.

RNA polymerase use coding strand of DNA molecule as a template to synthesize new mRNA molecule from that parental DNA molecule.
