Final answer:
The process of transferring genetic code information to RNA requires the breaking of hydrogen bonds between the base pairs of DNA during transcription. answer A is correct .
Step-by-step explanation:
The transfer of genetic code information to RNA requires the breaking of hydrogen bonds between complementary bases in DNA. During transcription, the enzyme RNA polymerase binds to the DNA molecule, causing the double helix to unwind. The hydrogen bonds between the base pairs are weak enough to be broken without the need for considerable energy, unlike covalent or ionic bonds.
This unzipping allows the RNA polymerase to read one strand of the DNA, called the template strand, and to synthesize messenger RNA (mRNA) by adding corresponding RNA nucleotides. The mRNA then carries the genetic information to the ribosome, where protein synthesis occurs. It is important to note that the stronger phosphate-sugar backbone of the DNA remains intact during this process, maintaining the structural integrity of the DNA molecule.
