Biology

Brrunno [24]3 years ago

Antibiotic used include kenamycin, ampicillin and tetracycline. This is useful to determine if and which bacteria took up the plasmid as they were supposed to during the process of recombination. Host bacteria are normally killed by these antibiotics. If the recombinant plasmids were taken up by the bacteria, plasmid may have contained a DNA gene for resisting the effects of one or more antibiotics. Host bacteria are placed in a growth medium containing an antibiotic to which they have a resistant gene in their recombinant plasmid DNA survivor. If they havent taken the plasmid they die.

In humans, the hormone testosterone enters cells and binds to specific proteins, which in turn bind to specific sites on the cel
Crank

Answer:

They act to regulate the expression of specific genes (androgen-responsive)

Explanation:

Testosterone is a reproductive hormone in male humans. Testosterone as well as its closely related hormones e.g dihydrotestosterone, all belong to a class of hormones called "Androgens".

Androgens operate by entering into a cell and binds with specific androgen-receptor proteins (AR proteins). This contact activates the AR proteins, forming an androgen-receptor complex.

This complex then translocates into the nucleus of specific cells to bind to the DNA. Once it binds, it either inhibits or promotes the expression of specific genes (androgen-responsive). Hence, AR proteins are transcription factors because they play a significant role in regulating transcription of specific genes i.e. turning 'on' or 'off' of specific genes.

This process helps to direct the development of male sexual characteristics.

How does water's specific heat relate to its usefulness for life give examples?
RideAnS [48]
<span>Water covers around 70% of the Earth's surface and its high specific heat plays a very important role as it is able to absorb a lot of heat without a significant rise in the temperature. When temperatures decrease, the heat which is stored is released, restraining a rapid drop in temperature. The combined effect of these processes is a buffering of temperature on the Earth.</span>
