What else can I help you with?
When the chromosomes make an exact copy of themselves what are they then called?
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.
What are the chemical called that are sometimes used to make the specimens visible?
The general term is 'stain' of which there are several chemicals that can be used, depending on the specimen.
What happens to chromosome during interphase?
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.
How many Chromosomes make up a human body?
46 chromosomes but 23 pairs
Which substance can a student use to make the nuclei more visible?
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.
When the chromosomes make an exact copy of themselves what are they then called?
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.
What are qualities of genes?
Genes are organized chromosomes. Chromosomes are what make the organism what it is. It is usually called DNA.
Did drake make a song called baby got a do do stain?
no.
What is the network of nuclear threads that condense to make chromosomes in mitosis called?
centromeres
What is the pairing of homologous chromosomes called?
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.
What kind of objects make up most of the visable matter in a galaxy?
stars
Traits are determined by pairs of genes called?
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.
Are the chromosomes visible through the microscopes used in school laboratories?
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.
Do chromosomes make copies of themselves?
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.
What color is the black box on plane?
They are actually luminus orange to make them more visable
Which thing make gram positive bacteria to get stain?
the smooth part of the cell wall make it to get stain
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
