Jupiter and Saturn are composed mostly of hydrogen and helium. Uranus and Neptune contain some of these gases, but also ices of ammonia and methane.
Explanation:
Many mRNAs have sequences of 50 - 150 nt rich in A and U in the 3' untranslated region. These sequences, called AU-rich elements, are important to regulate mRNA stability, because they bind proteins that target the mRNA for degradation.
When a protein binds to the AU-rich element of the mRNA, the polyA tail can be shortened and/or the 5'cap is removed, promoting mRNA degradation. In addition, the AU-rich elements in some mRNAs have been shown to inhibit protein translation.
The mRNA of the overexpressing cell line is about 200nt shorter than the normal cell line; this could mean that it has a deletion in the 3'UTR comprising an AU-rich element. If this is missing, the mRNA will have an extended half-life (because it won't be targeted for degradation) or it will be translated more. As a result, the protein expression will be increased.
Water is a limited resource, despite it being very useful. We still use it very often because there is a bountiful amount of it, but it is not abundant, obviously we have enough to last you and I, but we will eventually run out. If anything, it'll become rarer and increase in price, but I have a feeling we will either find water somewhere else, or die out before then.
Answer:
A) Steroid hormones travel in the plasma on large transport proteins that cannot pass through the filtration membrane
The right option is; -the single layer membrane surrounding the outside of the cell allows for the easy removal of waste
The cell membrane is a biological membrane that surrounds a cell and separates the contents of the cell from its external environment. The cell membrane is composed of lipids and proteins and its main function is to protect the cell from its surroundings. The cell membrane also controls the molecules that enter and leave cell.
