Duplication of chromosomes occur in?
The replication of the chromosomes occurs during interphase.
Where does duplication of chromosomes occur?
Inside the nucleus in eukaryotic cells. In the cytoplasm in prokaryotic cells.
What are the reproduction of chromosomes?
duplication
What is DNA called after duplication?
Chromosomes
Is duplication of paired chromosomes in the first stage of meiosis?
No, duplication of paired chromosomes occurs during the S phase of interphase before meiosis begins. In meiosis, homologous chromosomes pair up during prophase I.
What must happen before meiosis can begin?
DNA replicates and forms tetrad—APEX.
What mutation involves two chromosomes?
Inversion and duplication!
What are the types of chromosomes mutations?
Duplication, translocation, inversion, deletion.
What is mirroring chromosomes?
Mirroring chromosomes are a genetic abnormality. This abnormality is caused by an exact duplication of a chromosome segment, including the centromere.
Why does a cell double the amount of chromosomes?
it's called DNA duplication
Describe four types of mutations resulting from the breakage of chromosomes?
Deletion, duplication, inversion, translocation.
What is the relationship between divergence and amplification?
Gene duplication (or chromosomal duplication or gene amplification) is any duplication of a region of DNA that contains a gene; it may occur as an error in homologous recombination, a retrotransposition event, or duplication of an entire chromosome.
