RNA interference has potential applications in biotechnology and medicine, except for treating diseases characterized by genes that are not expressed.
<h3>What is RNA interference?</h3>
RNA interference (RNAi) or post-transcriptional gene silencing (PTGS) is a conserved biological response to double-stranded RNA that confers resistance to both endogenous parasites and exogenous pathogen nucleic acids, encoding proteins regulates the expression of genes.
<h3>What are the advantages of RNAi?</h3>
- RNA interference is a natural process involved in the regulation of protein synthesis and immunity.
- One of the advantages of RNAi technology is the rapid development of effective targeted drugs to control tumor growth. Therefore, cancer is one of the prime targets for RNAi-based therapy due to its high relationship with gene expression and cell proliferation.

Explanation:when we are hungry.we crave for food and eat.
the stimulus is when we are hungry
the response that come from brain is that order us to eat
the stimulie is internal.
hope this will help
Answer:
Option (1), (2) and (3).
Explanation:
DNA is the genetic material of all the living organisms present on earth. The DNA contains the nitrogenous bases, pentose sugar and the phosphate group. DNA strands runs in the opposite direction and shows polarity.
Watson and Crick explain the structure of DNA based on the X ray diffraction produced by Rosalind. According to the structure, chromosomes are present in the nucleus and contains the DNA and wrapped around the proteins. The genes is considered as the functional segment of DNA.
Thus, the correct answer is option (1), (2) and (3).

Resumen
El crecimiento de la población a nivel mundial y el aumento del uso del agua para diferentes actividades, ha
incrementado los niveles de contaminación. Esta contaminación está relacionada con los vertidos de origen doméstico e
industrial a los cuerpos de agua. En el caso de los residuos de origen doméstico, la carga contaminante está representada
por altos porcentajes de materia orgánica y microorganismos de origen fecal. Estos microorganismos son causantes de
enfermedades de origen hídrico, que generan altos porcentajes de morbi-mortalidad en la población. El control de la
calidad microbiológica del agua de consumo y de vertido, requiere una serie de análisis dirigidos a determinar la
presencia de microorganismos patógenos. El diagnóstico de estos microorganismos, requiere laboratorios especializados
y representa varios días de análisis y costos elevados. Como alternativa a estos inconvenientes, se ha propuesto el uso de
indicadores microbianos que se puedan identificar mediante el uso de métodos sencillos, rápidos y económicos. Este
trabajo hace una revisión de los principales indicadores de contaminación fecal y su significado en la evaluación de la
calidad del agua
