What happens in meiosis one that does not occur in meiosis two?
DNA is copied
Describe four types of mutation resulting from the breakage of chromosome?
Deletion: a segment of the chromosome is lost during breakage. Duplication: a segment of the chromosome is copied and inserted back into the chromosome following breakage. Inversion: a segment of the chromosome is reversed and re-inserted following breakage. Translocation: a segment of the chromosome breaks off and joins a different chromosome.
When is a bacterium's circular chromosome copied?
A bacterium's circular chromosome is copied during a process called DNA replication. This typically occurs before the bacterium divides through binary fission to ensure that each daughter cell receives a complete set of genetic information.
Why are chromosome copied before mitosis?
After Mitosis, the result is 2 new, identical, daughter cells. In order for each to be identical, the chromosomes must be copied.
When are chromosomes copied?
Chromosomes are copied during the S phase of the cell cycle, which occurs prior to cell division. This process is known as DNA replication, where each chromosome is duplicated to ensure that the daughter cells receive a complete set of genetic information.
What is the name of each chromosome after being copied?
it is called a sister chromosome :)
4 chromosome mutations?
Deletion: Part of a chromosome is missing. Duplication: A segment of a chromosome is copied multiple times. Inversion: A segment of a chromosome is reversed in orientation. Translocation: Part of a chromosome breaks off and attaches to another chromosome.
Are the chromosome copied before meiosis or during meiosis?
before
What common condition is caused by presence of three copied of chromosome 21?
Down syndrome
The place to which a selection is moved or copied?
It is usually referred to as the destination.
What happens in meiosis one that does not occur in meiosis two?
DNA is copied
A surrounds the selected range to be copied?
A flashing dotted line, sometimes referred to as marching ants, surrounds the area being copied.
Describe four types of mutation resulting from the breakage of chromosome?
Deletion: a segment of the chromosome is lost during breakage. Duplication: a segment of the chromosome is copied and inserted back into the chromosome following breakage. Inversion: a segment of the chromosome is reversed and re-inserted following breakage. Translocation: a segment of the chromosome breaks off and joins a different chromosome.
What do the four types of chromosomal mutations do?
The four types of chromosomal mutation are deletion, duplication, inversion and trasnlocation. Deletion is the loss of all or part of a chromosome. Duplication is where a segment of a chromosome is copied. Inversion is where a section of a chromosome is reversed. Translocation is the process in where a part of one chromosome breaks off and attaches to a non-homologous chromosome.
How a cells chromosome change as a cell prepares to divide?
the chromosomes are replicated (copied) and are compacted into dense visible structures
What command that inserts cut or copied item in the document?
This is generally referred to as 'Paste'.
What is copy area?
It is the selected area when a copy is done, and is also referred to as the source area. Whatever is in it is what will be copied and pasted to another area, often called the paste area or destination area.
