What else can I help you with?
What is the function of metaphase?
Eventually cells need to duplicate. There are two main methods of replication, mitosis and meiosis. This tutorial will talk about mitosis. The big idea to remember is that mitosis is the simple duplication of a cell and all of its parts. It duplicates its DNA and the two new cells (daughter cells) have the same pieces and genetic code. Two identical copies come from one original. Start with one; get two that are the same.
At the start of cell division what duplicates itself?
The chromosomes.
What is the resulting mutation when a a piece of chromosome attaches itself to a nonhomologous chromosome?
Translocations
When a piece of chromosome attaches itself to a nonhomologous chromosome the resulting mutation is called?
translocation
What stage of mitosis does the DNA double in a cell?
The DNA doubles during the S phase of interphase, which occurs before mitosis begins. In this phase, each chromosome is replicated, resulting in two sister chromatids for each chromosome. Mitosis itself consists of several stages—prophase, metaphase, anaphase, and telophase—but the actual doubling of DNA happens prior to these stages.
By which process does DNA duplicate itself?
The process in which DNA duplicates itself is called DNA replication. This process is an important factor in biological inheritance.
When the chromosome makes a copy of itself it is said to what?
duplicate or replicate
What step does each chromosome form an exact copy of itself?
Interphase
What is a terminal deletion?
A chromosome that lacks a partner and in which destroys or deletes itself.
When does the chromosome duplicate itself in its life cycle?
will replicate itself during the synthesis phase within its life cycle
When a chromosome is made of two identical parts are called?
Well in eukaryotic cells each chromosome has a telomere on each end (to prevent it from unraveling), but I'm not 100% certain that these telomeres are identical although they contain very long repetitions of the same nucleotides. But in bacteria the chromosome is ring shaped and is all genes (there are no noncoding sequences, e.g. centromeres, telomeres, introns, pseudogenes, transposons) so there are no identical parts.
Is it true or false The length of DNA ina chromosome may be as much as 10000 times as long as the chromosome itself?
True. The DNA in a chromosome is tightly packaged and condensed, so the actual length of DNA in a chromosome can be much longer than the physical length of the chromosome itself. This is possible due to the coiling and folding of DNA around histone proteins to form chromatin, allowing for a significant amount of genetic material to be compacted within a small space.
