The oxygen in the water molecule attracts the most electrons and in so doing attracts a slightly negative charge.
Answer:
miR-223 inhibits the expression of the fibroblast growth factor (bFGF) gene, and thereby ESCs cells maintain their undifferentiated state
.
Explanation:
Non-coding RNA (ncRNAs) are molecules that regulate gene expression, thereby playing important biological functions in cell differentiation, cell cycle, apoptosis, etc. MicroRNAs (miRNAs) are a type of ncRNAs capable of controlling gene expression patterns by regulating mRNA stability and by suppressing their translation into proteins. It has been shown that miRNAs function by imperfectly base-pairing with the 3′ UTR of target mRNAs (Pillai et al. 2005).

The two main clades branch from the most recent ancestor is called <span>Cnidaria and Bilateria. Please have in mind that Cnidaria is a phylum containing 10.000 species of animals. Now on the other hand, Bilateria is a major group of animals. After looing at the figure 33.2 we can conclude that these two are part of the ancestor of the eumetazoans which is a clade comprising all major animals. </span>
