This is false transcription does not follows the same base-pairing rules as DNA replication except for cytosine which has a different partner. Transcription begins with an enzyme called RNA polymerase.

Uracil takes the place of thymine in RNA. It pairs with adenine during transcription and translation processes.
Nitrogen bases are essential components of nucleic acids, such as DNA and RNA, which are fundamental to all forms of life. They encode genetic information through sequences that determine the synthesis of proteins, thereby influencing an organism's traits and functions. The specific pairing of nitrogen bases (adenine with thymine or uracil, and cytosine with guanine) ensures accurate replication and transmission of genetic material during cell division. This base pairing is critical for processes like transcription and translation, which are vital for cellular function and development.

The pairing of complementary nucleotides in RNA to match with the template DNA during transcription depends on the same base-pairing rule used in DNA replication. In both processes, adenine pairs with thymine (or uracil in RNA) and guanine pairs with cytosine.

Uracil is the nitrogen base found in RNA but not in DNA. It replaces thymine, which is found in DNA and not in RNA. Uracil forms base pairs with adenine in RNA during transcription and translation processes.
DNA replication produces a complimentary DNA strand. Transcription produces a complimentary mRNA strand. The major enzyme that carries out DNA replication is DNA Polymerase III (in prokaryotes). The major enzyme that carries out transcription is RNA Polymerase. DNA replication results in two copies of the DNA. Transciption does not affect the DNA - it simply re-anneals (re-joins) after the process. In DNA replication the complementary base to A is T. In transcription the complementary base to A is U.
Complementary base pairing is crucial in DNA replication and transcription because it ensures accurate copying of genetic information. During replication, the matching of bases (A with T, and C with G) allows for the faithful duplication of the DNA molecule. In transcription, base pairing helps in the synthesis of messenger RNA from the DNA template, enabling the correct transfer of genetic instructions for protein synthesis. Overall, complementary base pairing is essential for maintaining the integrity and fidelity of genetic information in living organisms.

The difference between transcription and DNA replication is that transcription uses uracil.
Helicase unwinds the double-stranded DNA by breaking the hydrogen bonds between complementary base pairs. This creates two single strands of DNA that can be used as templates for DNA replication or transcription.
Base pairing refers to the pairing of complimentary nitrogen bases, either during DNA replication, or transcription and translation. In DNA, the bases adenine and thymine pair together, and guanine and cytosine pair together. In RNA, the base uracil takes the place of the base thymine. The bases that pair together are said to be complimentary to each other.
The three major parts of DNA replication are initiation, where the DNA molecule unwinds and begins to replicate; elongation, where new DNA strands are synthesized by DNA polymerase; and termination, where replication is completed and two identical DNA molecules are produced.
RNA molecules produced by transcription are much shorter in length than DNA molecules produced by replication. Also in DNA replication the compliment of Adenine is Thymine. In transcription the compliment of Adenine is Uracil.
