What else can I help you with?
What did Walter Sutton observe?
he observed that grasshopper body cells and sex cells have the same number of chromosomes
When you observe a star on the celestial equator for a period of a few hours what can you notice?
moves from east-to-west relative to the horizon
Why cant you see the chromosomes during interphase?
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.
What can you use to observe cells going through mitosis?
You can use a light microscope with stained slides of cells to observe cells going through mitosis. Staining techniques such as using dyes like Hoechst or DAPI can make the chromosomes more visible under the microscope. Time-lapse imaging can also be used to track the progression of mitosis in real time.
Why are karyotypes prepared using cells in mitosis rather than cells in interphase explain.?
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.
What did Walter Sutton observe?
he observed that grasshopper body cells and sex cells have the same number of chromosomes
How do you write 3.2 million as numbers?
Observe ==> 3,200,000
The physical appearance of the entire set of chromosomes of a given animal?
The physical appearance of the entire set of chromosomes of a given animal is a phenotype. A phenotype is a trait that you can observe like the color of a persons eyes.
T is not easy to observe individual chromosomes during the interphase because?
Only during the division stages of a cells life will chromosomes form. During Interphase the cells DNA is in the unorganized form of chromatin.
What specific changes in the cell cycle of a plant cell would you expect to observe during mitosis?
During mitosis in a plant cell, you would expect to observe specific changes in the cell cycle such as the condensation of chromosomes, alignment of chromosomes at the cell's center, separation of sister chromatids, and the division of the cell into two daughter cells.
Why not easy to observe individual chromosomes during the interphase?
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
How do you calculate debtors more than six months?
We have to observe the numbers of them
When you observe a star on the celestial equator for a period of a few hours what can you notice?
moves from east-to-west relative to the horizon
What can you observer in a karytype?
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.
Why didn't Mendel observe linkage?
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.
What part of a cell would you study if you wanted to observe chromosomes?
Chromosomes are found only in the nucleus of the cell. Although they are actually observed as chromatinthroughout most of the cell's life the chromatin does condense into chromosomes during mitosis/meiosis.
Why use acetocarmine stain?
we use acetocarmine to stain chtomosomes. stained chromosomes distinguish from the other organels and materials, it gives the chromosomes a red color. it enables that, during the cell cyle we can observe the nucleus, duplication of DNA, and movement.
