Question

A(n) [____] has two properties that are essential for evolution: it carries information encoded

in its [____] that it can transmit by the process of replication, and it has a specific folded, three-
dimensional structure that enables it to interact selectively with other molecules as a [____]. The folded

three-dimensional structure is the phenotype of the molecule, and it is this expression of the genetic

information on which [____] operates.

(1) gene; nucleotide sequence; chromosome; evolution

(2) DNA molecule; base sequence; double helix; protein synthesis

(3) enzyme; amino acids; catalyst; RNA polymerase

(4) cell; genome; replicon; DNA polymerase

(5) RNA molecule; nucleotide sequence; catalytic molecule; natural selection

Explanation / Answer

(1) gene; nucleotide sequence; chromosome; evolution

A(n) [_gene___] has two properties that are essential for evolution: it carries information encoded in its [_nucleotide sequence___] that it can transmit by the process of replication, and it has a specific folded, three-dimensional structure that enables it to interact selectively with other molecules as a [_chromosome___]. The folded three-dimensional structure is the phenotype of the molecule, and it is this expression of the genetic information on which [__evolution__] operates.
