Answer:

(Wow! Weird how this pooped up, I just finished this biology lesson.)

Sex chromosomes are the gene that decides on our gender. The males have X and Y sex chromosomes (XY). Females have only two  X sex chromosomes (XX).

More info: Because males have both X and Y sex chromosomes, their genes decide the offspring's gender.

Alinara [238K]

Answer:

In eukaryotes, it is well known that polyadenylation is required to produce the mature messenger RNA (mRNA) molecule and it provides stability to the mRNA during translation initiation. In prokaryotic organisms, polyadenylation is required for the degradation of the mRNA in a mechanism that involves three steps: endonucleolytic cleavage, polyadenylation and exonucleolytic degradation. Moreover, it is also important to note that no evidence of polyadenylation has bee reported in some prokaryotes including the halophilic bacteria Haloferax volcanic (Slomovic et al. 2005).
