Answer:
knowledge of the sequence product
Explanation:
A gene knockout is a technique used in molecular genetics to deactivate target genes in an organism in order to study their functions by reverse genetics (i.e., gene loss). Knockouts are generated by different methods including, for example, homologous recombination or site-specific nucleases (zinc-fingers, TALENS, CRISPR/Cas9). These techniques require to know a priori the sequence of each gene to be knocked out in order to target desired mutations. In the last years, the CRISPR/Cas9 tool has gained attention to knockout genes of interest because it is a genome editing system that can be easily used for deletion or insertion of bases.
Answer:
The third option is correct.
Hope this helps.
Answer:
Organic molecules produced from spontaneous synthesis or from meteorites
Explanation:
<span>The correct answer is B. crepuscular activity. Crepuscular refers to animals and birds that are active at night, during twilight. So, these little birds don't usually travel large distances during the day, first of all, because they can't due to their small wings and plump bodies, and second of all, in order to avoid getting eating by a larger bird or animal. So they are usually nocturnal birds that live during the night.</span>
