What's the difference between meiosis ii and mitosis?
In both cases chromosomes line up and sister chromatids are separated by the action of the spindle fibers. The daughter cells are genetically identical to one another
How is the herbicide-resistance gene cut out of this structure?
One might find this answer when looking for books in a library on Genetic Engineering. Another way one might find out how the herbicide resistance gene is cut out of chromosomes by asking a genetic physicist.
Are beryllium atoms identical?
Each atom of an isotope of beryllium (or of another element) is different from the atoms of an other isotope. But all the atoms of an isotope are identical.
The Golgi apparatus is derived from another membranous intracellular structure?
the Golgi apparatus is derived from another membranous intracellular structure what it is
Chromosomes are made out of what molecule?
Chromosomes are DNA, which is made of sequences of nucleotides. Also there are some supporting factors such as proteint which help with it's structure and functioning. Nucleotides are molecules with a carbon-skeleton structure, about 3 small rings in size each. They bind in strings to other nucleotides quite strongly. One string binds less strongly to another string, but only if the nucleotides match (largely). In DNA there are four nucleotides, Adenine and Thymine which match, and Guanine and Cytosine which match.
What is the reason the cell undergoes mitosis when it makes another cell?
When a body cell reproduces, the purpose is to produce daughter cells that are genetically identical to the parent cell. Before mitosis, the DNA in the parent cell replicates, resulting in a doubling of the chromosomes. Mitosis separates the chromosomes into two new nuclei, identical to the parent cell. Then the cell divides by cytokinesis, producing two identical daughter cells, each with the same number of chromosomes as each other and the parent cell.
What do organisms produce through mitosis?
New cells of the same type and with the same number of chromosomes as the cell that underwent mitosis. a cell that under goes mitosis produces 2 new cells which are diploid in number and they are genetically identical to one another and to the parent
Threadlike structure within the nucleus containing the genetic info that is passed from one generation of cells to another?
The nucleus of a cell contains threadlike structures that contain genetic material called chromosomes.
How many of your genes do you get from your mother?
23 chromosomes. you get another 23 chromosomes from your dad
What does clone mean?
A cell or organism that is identical to another but is another individual form of it.
Why do non - identical same gender twins look like one another?
BECAUSE WHEN THEY WERE IN THE MOTHERS UTERUS< THE EGG THEY WERE IN SPLIT AND THATS HOW TWINS ARE MADE BUT SINCE THEY SPLIT THEY STILL HAVE THE SAME CHROMOSOMES AND THAT"S WHAT MAKES THEM LOOK ALIKE ---- But they are NON - identical! so the egg didn't split. There was 2 eggs! Can you explain in detail?

What is another word for matching chromosomes?
Homologous is the word used to describe matching chromosomes, with a homolog being a pair of homologous chromosomes.
What is another name for diploid cells?
Chromosomes
If I had identical twins 3 years ago what are my changes of having another set of identical twins?
The same as when you had the first set of identical twins.
Why does genetic deversity result in miosis one?
In prophase I there is a phenomenon known as genetic recombination or crossing over. Similar or homologous chromosomes get together to form a structure known as a tetrad. Two chromosomes (of the four= tetra) are originally from the parental sperm and the other two chromosomes are from the maternal source. Exchanging the DNA from one chromosome to another mixes the genes on these chromosomes so that after crossing over each chromosome is a mixture of maternal and paternal genes.
When binary fission is complete the result is two cells that each contain one copy of?
half the chromosomes of the original cell.
