Question

which best describes the outcome of dna replication? the new dna molecule is identical to the original dna. the new dna molecule is synthesized from amino acids. the new dna molecule has a different number of codons. the new dna molecule is single - stranded.

Explanation:

DNA replication is a semi - conservative process. Each new DNA molecule consists of one original strand and one newly synthesized strand. Due to the base - pairing rules (A - T and G - C), the new DNA molecule is an exact copy (identical) of the original DNA molecule.
Amino acids are used for protein synthesis, not DNA synthesis. DNA replication does not change the number of codons as the base - pairing ensures the genetic code (sequence of codons) is preserved. DNA is double - stranded, and replication maintains this double - stranded nature.

Answer:

The new DNA molecule is identical to the original DNA.
