which stain is used to colour chromosomes
When chromosomes make an exact copy of themselves, they are called sister chromatids. Sister chromatids are identical copies of a chromosome that are held together by a structure called the centromere.
The general term is 'stain' of which there are several chemicals that can be used, depending on the specimen.
During interphase, chromosomes are in a relaxed and extended state called chromatin. This allows for gene expression and DNA replication to occur. Chromosomes are not distinguishable structures during interphase, as they are not condensed and visible as separate entities.
46 chromosomes but 23 pairs
A student can use a stain called methylene blue to make nuclei more visible under a microscope. Methylene blue is commonly used in biology and histology to stain cells and highlight structures like nuclei.

Genes are organized chromosomes. Chromosomes are what make the organism what it is. It is usually called DNA.
no.
centromeres
The pairing of homologous chromosomes is called synapsis. It occurs during prophase I of meiosis when homologous chromosomes come together and exchange genetic material through a process called crossing over.

The two chromosomes (two "X" shapes) that are in a pair are generally called "homologous chromosomes". A pair of "chromatids" make up the two arms of a single chromosome.
Depends a bit on how high power your microscopes are, but probably, yes. You'd need to catch the cells during cell division, however, and then stain with something like Giemsa to make the chromosomes visible for light microscopy. The cells would need to be in metaphase ie. with condensed chromosomes.
Yes, chromosomes make copies of themselves through a process called DNA replication. During cell division, each chromosome is duplicated to ensure that each daughter cell receives an identical set of genetic material.
They are actually luminus orange to make them more visable
the smooth part of the cell wall make it to get stain
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
