While microRNAs (miRNAs) are encoded by the genome, short interfering RNAs (siRNAs) are added to cells by researchers. However, both miRNAs and siRNAs work by a similar mechanism. Based on this, which of the following do you expect researchers can learn by the use of siRNAs?Group of answer choicesThe location of any histone modifications.Patterns of alternative gene splicing.Quantitative mRNA expressionNull phenotypes of individual genes.The intracellular location of specific proteins.

Based on the information given, researchers can learn the "Null phenotypes of individual genes" by the use of siRNAs.

Here's why:

Both miRNAs and siRNAs work by a similar mechanism, which involves the regulation of gene expression. miRNAs are naturally occurring in the body and play a role in the regulation of gene expression. siRNAs, on the other hand, are synthetic molecules that researchers can design to target specific genes.

When siRNAs are added to cells, they can bind to and degrade specific messenger RNAs (mRNAs), preventing them from being translated into proteins. This process effectively "silences" the targeted gene, allowing researchers to study what happens when that gene is not expressed. This can reveal the "null phenotype" of the gene, or what happens when the gene is not functioning.

The other options (location of histone modifications, patterns of alternative gene splicing, quantitative mRNA expression, and intracellular location of specific proteins) are not directly related to the function of siRNAs.
