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 process where a DNA molecule makes an exact copy of itself. During replication, the double - stranded DNA unwinds, and each strand serves as a template for the synthesis of a new complementary strand. The base - pairing rules (A - T and G - C) ensure that the new DNA molecule has the same nucleotide sequence as the original DNA.
Amino acids are used in protein synthesis, not DNA replication. DNA replication does not change the number of codons as it is a faithful copying process. Also, the original DNA is double - stranded and the newly replicated DNA is also double - stranded (semi - conservative replication: each new DNA molecule has one old strand and one new strand, but overall it is double - stranded).

Answer:

The new DNA molecule is identical to the original DNA.
