When DNA replication takes place without subsequent cell division, polytene chromosomes may result. These are giant chromosomes comprised of multiple chromatids (identical chromosome copies) arranged together like strands of a large cable. They are commonly found in the salivary glands of the fruit fly (Drosophila melanogaster) and are regions of active transcription.

What substance is formed with eukaryotic DNA and protein?
I think it's chromosomes
How many chromosomes are in each cell formed after mitosis?
Mitosis produces daughter cells with the same number of chromosomes as the original cell - so human cells produced by mitosis will have 46 chromosomes.
How is an endospore formed?
The bacterium copies it's chromosomes and produces a wall around the copy.
Are tetrad and homologous chromosomes the same?
Homologous chromosome is when a pair of chromosomes containing the same linear gene sequences, each derived from one parent, and a tetrad is formed when 2 homologous chromosomes join together
Do animal cells have a chromosomes?
Yes, as a matter of fact, all living that reproduce via mitosis or meiosis will form chromosomes. Chromosomes are only formed during these ways of reproducing. At all other parts of a cell's life, chromosomes are stringy matter called chromatin.
In which animal polytene chromosome was discovered?
chromosomes were first discovered in a monkey.
The polytene chromosomes of certain insect larvae churn out copious amounts of gene products because?
they contain numerous side-by-side copies of genes.
What has the author Dahlia Arielle Kasimer written?
Dahlia Arielle Kasimer has written: 'Localization of general transcription factors and RNA polymerase II on Drosophila polytene chromosomes'
How many chromosomes are in a cell that was formed from a sperm and egg cell?
Twenty-three chromosomes are in a cell that is formed from a sperm and egg cell.
Was hybridization the ultimate source of genetic variability?
Often in reproduction, broken chromosomes are formed by random natural factors. When these combine with other chromosomes, new characteristics can be formed which are different from the Natural Chromosomes.
What formed element does not have chromosomes?
The formed element that does not have chromosomes is the red blood cell (erythrocyte). Red blood cells are lacking in a nucleus and do not contain chromosomes or genetic material. This feature allows them to maximize their capacity for carrying oxygen.
What part of the nucleus is chromosomes formed from?
From DNA.
What DNA molecules are formed into structures?
Chromosomes
How does the number of chromosomes in sex cell compare to the number of chromosomes in cells formed during mitosis?
it compares by 50% or by half of chromosomes because there are 23 sex cells and 46 chromosomes
How does the number of chromosomes in sex cells compare to the number of chromosomes in cells formed during mitosis?
it compares by 50% or by half of chromosomes because there are 23 sex cells and 46 chromosomes
How does the number in chromosomes in sex cells compare to the number of chromosomes in cells formed during mitosis?
it compares by 50% or by half of chromosomes because there are 23 sex cells and 46 chromosomes
How many chromosomes are in each daughter cell of a human cell formed by mitosis?
46 chromosomes or 23 pairs
