The first major difference between prokaryote and eukaryote gene expression is the location. Due to lack of compartments (nucleus) prokaryotic gene expression (both transcription and translation) occurs within the cytoplasm (genetic material is located within the cytoplasm). So, transcription and translation in prokaryote occurs simultaneously. Gene expression in eukaryote occurs in both the nucleus (transcription) and cytoplasm (translation).
The steps of regulation of gene expression are also dissimilar, in prokaryotic cell, transcription is mostly the main point of regulation (eukaryote have transcription, post-transcription, translation, and post-translation regulation together with epigenetic regulation).
Answer:
1) In the first step, we need to predict the possible alleles for the cross. The dominant allele will be written with a capital letter. The recessive allele will be written with a small letter. Hence, the allele for brown hair colour will be B and the allele for red hair colour will be b.
2) In the second step, we need to determine the genotype of the parents. The genotype of the homozygous dominant parent will be BB. The genotype of the heterozygous brown hair colour will be Bb.
3) The punnet square for cross between these parents can be shown as follows:
B b
B BB Bb
B BB Bb
4) In the fourth step, lets determine the phenotype of the children. The phenotype of all the offsprings born will be brown hair colour.
5) The genotype from the punnet square shows that there is a 50% chance that the offsprings will be heterozygous dominant (Bb) for brown hair colour and their will be a 50% chance that the child born will be homozygous dominant (BB).
ER membranes flow to Golgi through ERGICs and get fragmented into small vesicles. When the cell divides, those vesicles within the daughter cells reassemble Golgi and ER to resume membrane traffic
To find the average they also take into account the salary of the president, who probably makes a lot more than $20,000.
