Question

question 5 0.5 pts which of the following describes a eukaryotic chromosome after dna replication? a structure containing two sister chromatids, with each sister chromatid containing one dna molecule. a structure containing two sister chromatids, with each sister chromatid containing one single dna strand. a structure containing one sister chromatid that is composed of two dna molecules.

Explanation:

After DNA replication in eukaryotes, a chromosome consists of two sister chromatids. Each sister chromatid contains one DNA molecule which is a double - stranded structure. The second option is incorrect because each chromatid has a complete DNA molecule (double - stranded) not a single strand. The third option is incorrect as there are two sister chromatids after replication, not one, and each chromatid has one DNA molecule.

Answer:

A. A structure containing two sister chromatids, with each sister chromatid containing one DNA molecule.
