Answer:
DNA
Explanation:
you can tell if the DNA is within the nucleus in the cell then it is eukaryotic but if the DNA is free floating in the cell then it's prokaryotic
Explanation:
Xenopus laevis is allotetraploid: it has 2 sets of homologous chromosomes originally from one species and 2 sets of homologous chromosomes originally from another species, making a total of 4 sets of chromosomes. During meiosis, every chromosome has another homologous one with which it can pair, producing viable gametes that have the complete genetic information of the species.
Mules, however, are allodiploid: they have one set of chromosomes from a donkey and another set from a horse, making a total of 2 sets of chromosmes. But those two sets are not homologous, so during meiosis the chromosomes can't pair and the gametes will have errors that make them inviable, making mules sterile
Answer:
Phosphorylation within the nuclear export signal interferes with the function of the signal.
Explanation:
In biochemistry, phosphorylation is the addition of a phosphate group (PO4) to a protein or other molecule. Phosphorylation is a major player in protein regulation mechanisms, preventing protein-catalyzed reaction product from accumulating in the body causing problems.
However, in some cases phosphorylation may cause nuclear accumulation of a protein in the nucleus of the cell. An example of this is the protein shown in the question above. In this case, phosphorylation in the nuclear export signal interferes with the signal function, resulting in protein accumulation in the nucleus.
