During mitosis, a cell divides once to produce two daughter cells with genetic material identical to that of the original parent cell and to each other. Both haploid and diploid cells can undergo mitosis.
Do haploid cells replicate DNA?
The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Is it possible for a haploid cell to undergo mitosis?
Both diploid and haploid cells can undergo mitosis. … If a haploid cell undergoes mitosis, which is something certain types of plant and fungus do as part of their normal life cycles, the end result is two identical haploid cells (n→n).
Do haploid cells have double stranded DNA?
A replicated chromosome contains two identical double strand -DNA- molecules, the chromatids, that are joined at their centromere. Haploid is the term for a cell or an organism with only one set of chromosomes (n). If this is valid for all cells, the entire organism is regarded as being haploid.
Can meiosis replicate DNA?
Like mitosis, meiosis is a form of eukaryotic cell division. Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. … These new combinations result from the exchange of DNA between paired chromosomes.
What type of cells are created during mitosis?
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells.
What does N and 2N stand for in genetics?
– Genomic (X) number is a set of different chromosomes 2N = number of chromosomes in somatic cells (somatic chromosome number) N = number of chromosomes in gametic cells (gametic chromosome number) X = Number of chromosomes in a genome complement (genomic chromosome number) 4.
Can a chromosome have one chromatid?
When fully condensed, replicated chromosomes appear as thick X-shaped structures that are readily observed under the microscope (see figure below). Chromosomes can have 1 or 2 chromatids, depending on whether they have replicated.
