When an two organisms mate, they will contribute a gamete with a haploid cell (n=12). Now take into consideration of sperm and egg. Father parent gives: n=12 (sperm) Mother parent gives: n=12 (egg) The fusion of both the haploids (each n=12, sperm and egg) results in a somatic cell (2n=24).Therefore, the organisms will have have 24 chromosome. The organism will inherit one of set of 12 chromosomes from the father and the mother.ather parent gives: n=12 (sperm) Mother parent gives: n=12 (egg) The fusion of both the haploids (each n=12, sperm and egg) results in a somatic cell (2n=24).

Transcription is the process of copying genetic information stored in a DNA strand into a transportable complementary strand of RNA. Eukaryotic transcription takes place in the nucleus of the cell and proceeds in three sequential stages: initiation, elongation, and termination.nce the initiation complex is open, the first ribonucleotide is brought into the active site to initiate the polymerization reaction in the absence of a primer. This generates a nascent RNA chain that forms a hetero-duplex with the template DNA strand.
In eukaryotes, a core promoter sequence in the DNA must be present for RNA polymerase to initiate transcription. Promoters are regions of DNA that promote transcription-in eukaryotes, they are found at -30, -75, and -90 base pairs upstream from the transcription start site (abbreviated to TSS). One or more sigma factor protein binds to the RNA polymerase holoenzyme, allowing it to bind to promoter DNA. 2  RNA polymerase creates a transcription bubble, which separates the two strands of the DNA helix. 3  This is done by breaking the hydrogen bonds between complementary DNA nucleotides.
