In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles. In telophase, chromosomes arrive at opposite poles, and nuclear envelope material surrounds each set of chromosomes. Finally, in cytokenesis, the two daughter cells are separated.
What is the major difference between metaphase and anaphase?
During metaphase,: chromosomes are arranged in the equatorial plane, whereas during anaphase, daughter chromosomes move towards the Opposite poles of the spindle.
What is the difference between prophase and telophase?
As nouns the difference between telophase and prophase
is that telophase is (biology) the final stage of mitosis or meiosis during which the daughter chromosomes move towards opposite ends of the nuclear spindle while prophase is the first stage of mitosis, during which chromatin condenses to form the chromosomes.
What is the significance of anaphase I?
Anaphase is a very important stage of cell division. It ensures that duplicated chromosomes, or sister chromatids, separate into two equal sets. This separation of chromosomes is called disjunction. Each set of chromosomes will become part of a new cell.
What are the five stages of prophase 1?
Meiotic prophase I is subdivided into five stages: leptotene, zygotene, pachytene, diplotene, and diakinesis.
How is DNA organized into a chromosome?
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
What are two reasons cells must divide?
The two reasons why cell divides are:
- Replacing damaged or dead cells.
What is telophase mean in science?
Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. … During telophase, a nuclear membrane forms around each set of chromosomes to separate the nuclear DNA from the cytoplasm.
