Question

following dna replication, each eukaryotic chromosome consists of two identical dna molecules known as sister chromatids sister chromatins sister cohesins daughter chromosomes

Explanation:

DNA replication occurs during the S - phase of the cell cycle. In eukaryotes, after DNA replication, each chromosome consists of two identical DNA molecules.

• Sister chromatids: These are the two identical DNA molecules (along with associated proteins) that are joined at the centromere. They are formed as a result of DNA replication.
• Sister chromatins: Chromatin is the complex of DNA and proteins. The term "sister chromatins" is not a standard biological term in this context.
• Sister cohesins: Cohesins are proteins that hold sister chromatids together, not the DNA molecules themselves.
• Daughter chromosomes: Daughter chromosomes are formed when sister chromatids separate during anaphase of mitosis or meiosis II. Before separation, they are called sister chromatids.

Answer:

A. sister chromatids
