the DNA has not been duplicated yet. they have uncoiled to form long, thin strands. they leave the nucleus and are scattered throughout the cell. homologous chromosomes do not pair up until division starts.
this is because during the interphase, the cell is at a point where it has either completed its division or is about to start its division. here the chromosomes have not separated yet in preparation for the divisin and they so look alike that one cant differentiate a chromosome.
Because everyone has a responsibility for the safety of themselves and everyone else.
To develop a hypothesis you need to observe and make an educated guess, by starting the sentence with "If...then.....because...."
How
because they need to observe what they are working on, hypothesize and predict what the outcome will be, and experiment to see if they are correct.
Only during the division stages of a cells life will chromosomes form. During Interphase the cells DNA is in the unorganized form of chromatin.
In interphase, the DNA has just replicated and exists as loosely coiled chromatins. They have not yet condensed enough to be the form of a chromosome. In the next stage, prophase, the DNA will shorten and condense into the easily recognizable chromosome structure.
coz in interphase, the chromatin threads are not yet condensed into what is called as chromosomes. they are thread like structures, and make a network called chromatin network. chromatin threads only begin to condense into thicker structures called chromosomes once the process of cell division actually begins
this is because during the interphase, the cell is at a point where it has either completed its division or is about to start its division. here the chromosomes have not separated yet in preparation for the divisin and they so look alike that one cant differentiate a chromosome.
in mitosis (specifically Prophase) the chromosomes are dense and therefore visible for a karyotype. during interphase they do not have to be ready to be pulled apart so they are not wound tightly.
The filamentous DNA and protein components that can be stained in interphase nuclei are chromosomes. Chromosomes consist of DNA and associated proteins, and can be visualized through staining techniques to observe their organization and structure within the nucleus during interphase.
It is important because the individual can dispose of the medication
DNA is changing its shape. It wraps two loops around histones, becoming nucleosomes, shaping into spiral coils known as chromatin. Because we have so much DNA is our genes, if we line it up it would reach the moon back and forth many times.
The interphase stage of the cell cycle is the one that can be most readily identified with a light microscope. This is because during interphase, the cell is carrying out its normal functions and the nucleus is clearly visible. The chromosomes are in their extended form and not condensed as they are during mitosis, making them easier to observe under a light microscope.
A karyotype displays the number, size, and shape of an organism's chromosomes. By analyzing a karyotype, you can observe the total number of chromosomes, detect any abnormalities like chromosomal mutations or aneuploidies, and identify the sex chromosomes in the individual.
Mendel did not observe linkage because, by chance, he chose traits whose genes resided on different chromosomes. Genes on different chromosomes assort independently. To answer the question of 'Who discovered gene linkage?'...The answer is British geneticists William Bateson and Reginald Punnett.
In the early stages of mitosis or meiosis (cell division), the chromatin strands become more and more condensed. They cease to function as accessible genetic material (transcription stops) and become a compact transportable form. This compact form makes the individual chromosomes visible, and they form the classic four arm structure, a pair of sister chromatids attached to each other at the centromere. The shorter arms are called p arms (from the French petit, small) and the longer arms are called q arms (q follows p in the Latin alphabet). This is the only natural context in which individual chromosomes are visible with an optical microscope.
