What is the role of the condensin protein in the process of chromosome condensation during cell division?
Condensin proteins play a crucial role in chromosome condensation during cell division by helping to compact and organize the DNA into tightly coiled structures. This condensation process ensures that the chromosomes are properly segregated and distributed to daughter cells during cell division.
What structures in cells contain DNA and protein?
Nucleus.
What happens to the nucleus during prophase of cell division?
During prophase of cell division, the nucleus condenses and the chromatin (DNA and proteins) inside it becomes tightly coiled into chromosomes. The nuclear membrane also breaks down, allowing the chromosomes to become more visible and ready for division.
Why is DNA coiled up and packed into chromosomes?
DNA is coiled up and packed into chromosomes to ensure that it can be efficiently stored and organized within the cell. This compact packaging helps protect the DNA from damage and allows for the precise distribution of genetic information during cell division.
At the end of s phase each chromosome has how many coiled dna molecules?
At the end of S phase, each chromosome has two coiled DNA molecules, also known as sister chromatids. These sister chromatids are identical copies of each other formed during DNA replication in preparation for cell division.
What is the role of the condensin protein in the process of chromosome condensation during cell division?
Condensin proteins play a crucial role in chromosome condensation during cell division by helping to compact and organize the DNA into tightly coiled structures. This condensation process ensures that the chromosomes are properly segregated and distributed to daughter cells during cell division.
What is chromonematta in genetics?
The chromonemata is an individual coiled chromosome thread. The chromonemata is the coiled mass of threads visible within the nucleus at the beginning of cell division. During cell division, it remains relatively uncoiled during early prophase but assumes a more spiral shape during metaphase.
What structures in cells contain DNA and protein?
Nucleus.
When chromosomes are visible?
Chromosomes are visible during prophase. Chromosomes are only visible in cells during the cell division because the DNA and protein that the chromosomes are made of are spread throughout the nucleus.
What happens to the nucleus during prophase of cell division?
During prophase of cell division, the nucleus condenses and the chromatin (DNA and proteins) inside it becomes tightly coiled into chromosomes. The nuclear membrane also breaks down, allowing the chromosomes to become more visible and ready for division.
The two coiled up strands of DNA within a chromosome are called?
The two coiled up strands of DNA within a chromosome are called chromatids. During cell division, chromatids separate and are distributed to daughter cells.
Why is DNA coiled up and packed into chromosomes?
DNA is coiled up and packed into chromosomes to ensure that it can be efficiently stored and organized within the cell. This compact packaging helps protect the DNA from damage and allows for the precise distribution of genetic information during cell division.
At the end of s phase each chromosome has how many coiled dna molecules?
At the end of S phase, each chromosome has two coiled DNA molecules, also known as sister chromatids. These sister chromatids are identical copies of each other formed during DNA replication in preparation for cell division.
What does a chromosome look like during metaphase in the process of cell division?
During metaphase in cell division, a chromosome looks like a condensed and tightly coiled structure that is visible under a microscope. It appears as an X-shaped structure with two identical sister chromatids joined at the centromere.
How are sister chromatids joined at the centromere during cell division?
During cell division, sister chromatids are joined at the centromere by protein complexes called cohesins. These cohesins hold the sister chromatids together until they are separated during the later stages of cell division.
Protein production is high in interphase or mitosis?
Protein production is higher in interphase, particularly during the synthesis (S) phase. During mitosis, cell division takes precedence over protein synthesis, so protein production is typically lower.
What form a spindle shape structure of protein fibres on which the chromosomes move durung nuclear division?
The spindle shape structure of protein fibers that chromosomes move on during nuclear division is called the mitotic spindle. This structure is made up of microtubules that are responsible for segregating the chromosomes into the daughter cells during cell division.
