Which of the following best describes sister chromatids?

Which of the following defines sister chromatid?

A sister chromatid refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. In other words, a sister chromatid may also be said to be ‘one-half’ of the duplicated chromosome. A pair of sister chromatids is called a dyad.

Which of the following statements best define sister chromatid?

Sister chromatids are identical copies of each other produced during DNA replication.

What are sister chromatids simple definition?

Medical Definition of sister chromatid

: either of the two identical chromatids that are formed by replication of a chromosome during the S phase of the cell cycle, are joined by a centromere, and segregate into separate daughter cells during anaphase.

What are sister chromatids quizlet?

Sister chromatids are identical copies of each other produced during DNA replication. One homologous chromosome comes from the father, and the other comes from the mother. Sister chromatids are identical copies of each other.

What is the purpose of a sister chromatid?

The primary function of sister chromatids is to pass on a complete set of chromosomes to all the daughter cells formed as a result of cell division. During mitosis, they are attached to each other through the centromere – a stretch of DNA that forms protein complexes.

How does one chromatid compare to its sister chromatid?

One chromatid compares to its sister chromatid because when a chromatid is replicated, a sister chromatid is formed. The sister chromatid will be a genetically identical copy to the chromatid because the cell being replicated will also be genetically identical.

Which of the following is not true for sister chromatid?

The correct answer is option C. The statement falsely describes sister chromatids. The sister chromatids only join together during the prophase stage of cell division. Prior to prophase, the chromatids are still uncoiled inside the nucleus of the parent cell.

What is the difference between a sister chromatid and a chromosome?

Chromosomes carry DNA, which is the genetic material of that organism. … One copy of the gene comes from each parent to the organism. Sister chromatids, on the other hand, are identical copies of one another.

What are sister chromatids and when are they formed quizlet?

Sister chromatids are only formed during mitosis. Homologous chromosomes are formed during meiosis. … Homologous chromosomes contain the same gene loci but may have different alleles of a particular gene. Sister chromatids are identical copies of each other produced during DNA replication.

Where do we find sister chromatids?

Before anaphase begins, the replicated chromosomes, called sister chromatids, are aligned at along the equator of the cell on the equatorial plane. The sister chromatids are pairs of identical copies of DNA joined at a point called the centromere.

What are sister chromatids and non sister chromatids?

A sister chromatid is either one of the two chromatids of the same chromosome joined together by a common centromere. … Non-sister chromatids, on the other hand, refers to either of the two chromatids of paired homologous chromosomes, that is, the pairing of a paternal chromosome and a maternal chromosome.

In what process are sister chromatids formed quizlet?

Sister chromatids form in the S-phase stage of the cell cycle. Both of the sister chromatids end up in the same daughter cell after cytokinesis has occurred.

What happens to sister chromatids in meiosis II quizlet?

Sister chromatids of each replicated chromosome are pulled apart at the centromere. Sister chromatids (now called single chromosomes) migrate to opposite ends of the cell.

What happens to the sister chromatids in meiosis II?

In meiosis II, the sister chromatids separate, making haploid cells with non-duplicated chromosomes.
