How are sister chromatids attached
WebBiology questions and answers. How are sister chromatids assembled into a chromosome? A. Joined together by the kinetochore and attached to a histone-based … WebAnaphase. During anaphase, sister chromatids separate and the centromeres divide.The sister chromatids are pulled apart by the shortening of the spindle fibers. This is like reeling in a fish by shortening the fishing line. One sister chromatid moves to one pole of the cell, and the other sister chromatid moves to the opposite pole.

They argue that the first step is the hardest and most important, and that understanding how it evolved would make the evolutionary process … WebOverview. Chromosomes are linear arrangements of condensed deoxyribonucleic acid (DNA) and histone proteins, which form a complex called chromatin. Homologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding …

During the next stage of meiosis, called Prophase I, chromosomes with similar sequences form pairs and undergo recombination, creating physical links that hold the homologs together.
Web6 de abr. de 2024 · Sister chromatids are formed during DNA replication, when the DNA molecule unwinds and each strand serves as a template for the synthesis of a new complementary strand. The resulting two identical DNA molecules remain joined together as sister chromatids until they separate during cell division.
