Chromosomal material replicates during mitosis. Chromosomes become sister chromatids, which ultimately break off to form identical chromosomes and two identical cells.
Bacteria carry plasmids which is a double stranded DNA . It is how their extra chromosomal DNA is stored, they also have chromosomal DNA.Plasmids are extra-chromosomal DNA in Bacterial cells that replicate independently in cell. Plasmids are ubiquitous- means significant number of bacteria have plasmid and can have more that one plasmids. But Plasmids do not occur in all bacterial isolates.
The chromosomal hereditary material is packaged in the nucleus in eukaryotic cells but not in prokaryotic cells.
Chromosomal Dna.
Extra-chromosomal DNA particles capable of independent replication are called plasmids. Plasmids are circular DNA molecules found in bacteria that can replicate independently of the chromosomal DNA. They often carry additional genes that can provide advantages to the bacteria, such as antibiotic resistance.
Chromosomal defects in offspring. Because no genetic material is lost with inversion of genetic material, individuals often have no obvious physical effects. The major risk with the inversion of genetic material is that offspring of these individuals may have more severe chromosomal abnormalities.
Chromosomes are replicated during DNA replication, which occurs during interphase.
interphase
The nucleus.
Nucleus
DNA is heredity material because it has the ability to replicate its self afer the zygote is formed
Interphase == == == ==
This organelle is called the nucleus.
