Detailed explanation-1: -The process of breaking the hydrogen bonds between the nucleotide base pairs in double-stranded DNA requires energy. To break the bonds, helicases use the energy stored in a molecule called ATP, which serves as the energy currency of cells.
Detailed explanation-2: -Transcription can be explained easily in 4 or 5 simple steps, each moving like a wave along the DNA. RNA polymerase unwinds/"unzips” the DNA by breaking the hydrogen bonds between complimentary nucleotides.
Detailed explanation-3: -The major enzyme of transcription is called RNA polymerase, and it first binds to the promoter region of a gene in DNA. Next, RNA polymerase unwinds the double-stranded DNA molecule. It does this by breaking the hydrogen bonds between base pairs.
Detailed explanation-4: -Explanation: Helicases are enzymes involved in the unzipping of the double-stranded DNA molecule at beginning of DNA replication. They do so by binding at DNA sequences called origins on DNA molecule then they break the hydrogen bonds between complementary base pairs causing the two strands of DNA molecule to unzip.
Detailed explanation-5: -The base pairs are stabilized by hydrogen bonds; adenine and thymine form two hydrogen bonds between them, whereas cytosine and guanine form three hydrogen bonds between them.
