Aquaporins are proteins that control the passage of water molecules across a cell membrane. The protein forms a pore, or opening
timofeeve [1]

The two different molecules of aquaporin will have different sequences of amino acids

Explanation:

Aquaporins are an integral type of membrane proteins. They act as water channels and their function is to transport water and other solute materials across cells membranes and thereby control and regulate the water content of the cells.

They are formed by clustering of four water channel monomers forming a tetramer.

Each aquaporin is made up of a specific linear sequence of amino acids and variations in the sequence leads to formation of different aquaporins.

There are more than 10 types of aquaporins are known. The sizes of the aquaporins differ according to their pore diameter of each type and this difference leads to the selective permeability of water across cell membranes.

Provide evidence to reject this statement, "Human phenotypes are usually a clear cut either situation"
tensa zangetsu [6.8K]
Wavy hair is a very easy example that this is false.  It's a merge between straight and curly hair.  Our traits tend to mix and blend together, it's not so simple.  Everybody isn't just tall or short, one or the other.  Everybody is a different height because it's a mid between your parents.

A geneticist introduces a transgene into yeast cells and isolates five independent cell lines in which the transgene has integra
Zina [86]

Answer:

A) A transgene integrated into a heterochromatic region of the genome.

Explanation:

This is most likely the reason why the transgene is not expressed in the fifth cell line. It is likely that the transgene was integrated into a heterochromatic region of the genome. Heterochromatin consists of genetically inactive satellite sequences, and many of these are repressed to various extents. Moreover, because this is a tightly packed form of DNA or condensed DNA, it is inaccesible to polymerases and thus not transcribed.

Thale cress is a plant that is genetically engineered with genes that break down toxic metals. Which type of organism is describ
Misha Larkins [42]

Any genetically engineered organisms is referred to as a transgenic organism.

A transgenic organism is any organism that was modified genetically or engineered by humans, for certain purposes, in this case, the function of the thale cress is to break down toxic metals in the water (cress plants grow on water).

Hope it helped,

Happy homework/ study/ exam!
