What is the name of the semiconservative process in which DNA duplicates into two identical molecules?

Correct option is A

The correct answer is (A) Replication

Explanation:
• DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.
• This process occurs in all living organisms and is the basis for biological inheritance, ensuring that each daughter cell receives a complete set of genetic instructions during cell division.
• It is described as 'semiconservative' because each of the newly formed double-stranded DNA molecules contains one original (parent) strand and one newly synthesized strand, perfectly conserving half of the original structure.

Information Booster:
• Key Enzyme: The primary enzyme responsible for synthesizing the new DNA strand is DNA Polymerase, which adds nucleotides sequentially matching the template strand (A pairs with T, C pairs with G).
• Central Dogma of Biology: The fundamental framework of genetics involves three steps: DNA replicates itself -> DNA is transcribed into RNA -> RNA is translated into proteins.

Additional Knowledge:
• Option B (Transcription): This is the process of copying a segment of DNA into RNA (specifically mRNA). It does not produce a new DNA molecule.
• Option C (Mutation): A mutation is a random error, alteration, or damage in the DNA sequence. It is an anomaly, not the standard duplication process.
• Option D (Translation): This occurs in the ribosomes, where the sequence of an mRNA molecule is read to assemble amino acids into a specific functional protein.
