Which best describes the outcome of DNA replication? The new DNA molecule consists of one strand of DNA. The new DNA molecule accumulates a new strand of DNA with each replication. The new DNA molecule consists of one new strand and one old strand of DNA. The new DNA molecule contains new DNA, and the old molecule keeps the old DNA.

The new DNA molecule consists of one new strand and one old strand of DNA.

If the same base pairs are used to code for all organisms, why is there so much variation among organisms? The order of the codons differs between organisms. The order of the codons is the same between organisms. The codons in each organism are the same. The codons in each organism differ.

The order of the codons differs between organisms.
