• D. Transcription

Answer: (B)

Verified step by step guidance

1. Begin by understanding the key processes related to DNA: replication, transcription, translation, and sequencing.
2. DNA replication is the process by which a cell duplicates its DNA, creating two identical copies. It involves enzymes like DNA polymerase.
3. Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, which is then used in protein synthesis.
4. Translation is the process where ribosomes synthesize proteins using mRNA as a template, converting nucleotide sequences into amino acid sequences.
5. DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. It involves techniques like Sanger sequencing or next-generation sequencing to read the sequence of bases (adenine, thymine, cytosine, and guanine) in a DNA fragment.
