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
How does polyploid speciation occur through hybridization and subsequent genome duplication?
Polyploid speciation occurs when two different species interbreed, resulting in a hybrid offspring with an extra set of chromosomes. This extra set of chromosomes can come from one or both parent species. The hybrid offspring may then undergo genome duplication, resulting in a new species that is polyploid. This process can lead to the formation of a new species with a different number of chromosomes than either parent species.
Describe four types of mutations resulting from the breakage of chromosomes?
Deletion, duplication, inversion, translocation.
