The replicas of chromosomes that form during prophase are called what?
During prophase, a chromosome is composed of tightly coiled DNA and protein molecules. Each chromosome exists as a pair of identical sister chromatids which are held together at the centromere.
Are telomeres the regions of chromosomes that code for protein?
No, they don't code for anything. They are repetitive sequences at the ends of chromosomes that protect them from gene loss during cell division. Genes code for protein or RNA.
How is plant cell division like animal cell division?
Plant cell division is like animal cell division in all other aspects, but unlike animal cell, a plant cell lacks centriole, by which spindle fibre produce during metaphase stage. But in plant cell, spindle fibre are produced from protein rich material, i.e. the pole.
During cell division chromatin threads from the?
During cell division chromatin threads from the chromosome.
Why is it more important to check for errors during DNA replications than during protein synthesis?
Because if an error is made during protein synthesis, the result is at worst one bad protein. If an error is made during DNA replication, that error will persist for the entire lifespan of that cell and be inherited by every daughter cell it produces. Should the error prove deleterious, the effects can be catastrophic for the cell or the organism. For example, if an error occurs in a protein coding segment of DNA, it is possible that every protein that locus generates will now be defective.
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.
When do chromosome form?
The DNA-protein complex, called chromatin usually folds into characteristic formations called chromosomes. Each chromosome contains a single double stranded piece of DNA. Chromosomes are clearly seen during nuclear division.
Job of chromosomes?
the job of a chromosome is that it contains genetic information that is passed from one generation to the next.
What does not occur during interphase excretion of wastes cell repair protein synthesis nuclear division?
you probably asked this a long time ago but the answer is nuclear division, because interphase is befor cell division. :)
What does the chromosomes of a cell do?
The chromosomes in a cell carry genetic information called DNA. DNA strands are coiled and then coiled again (supercoiled) to create chromosomes. Chromosomes are only visible in cells during Mitosis (division of the cell). Chromotids (Paired Chromosomes) split during Mitosis to give each daughter cell identical information. So in general chromosomes carry strands of DNA and DNA carries the genetic information for all organisms and DNA also replicates to form RNA which produces protein chains (chains of amino acids) for the organism and cells to use.
The replicas of chromosomes that form during prophase are called what?
During prophase, a chromosome is composed of tightly coiled DNA and protein molecules. Each chromosome exists as a pair of identical sister chromatids which are held together at the centromere.
What is the period of the cell cycle during which activities such as cell growth and protein synthesis occur without visible signs of cell division?
introphase.
What is the role of the nucleolus in cell division?
to divide the cell in half, resulting in the process of meiosis i dont know what a nucleolus does really but its in the middle f the nucleus so it must be important It is not involved in cell division. it disappears during beginning of cell division and reappears during telophase of cell division. Nucleolus helps in the synthesis of Ribosomes (organelles that help in protein synthesis).
What are the spindle fibers eventually used for?
Spindle fibres are tiny tube-like structures made of protein to which chromosomes attach during cell division.
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.
Are telomeres the regions of chromosomes that code for protein?
No, they don't code for anything. They are repetitive sequences at the ends of chromosomes that protect them from gene loss during cell division. Genes code for protein or RNA.
