Answer:
Non-coding DNA regions play important roles in regulating transcriptional activity by encoding different types of non-coding RNAs (ncRNAs), acting as scaffold attachment regions, acting as enhancer specific regions, etc.
Explanation:
Historically, it had been believed that non-coding DNA sequences were 'junk DNA' since they don't encode for proteins (beyond the sequences that are transcribed into functional non-coding RNAs, i.e., transfer RNA and ribosomal RNA). However, in the last years, it has been shown that non-coding DNA sequences play critical roles in regulating gene expression and genome function. For example, evolutionary conserved non-coding RNAs (ncRNAs) with regulatory roles on gene expression such as, for example, long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) have been mapped in non-coding DNA sequences, thereby evidencing the functional significance of these regions. In consequence, the conservative nature of certain non-coding DNA sequences evidence that mutations in such regions may have significant deleterious effects, and thereby they could have a negative impact on the fitness of the individual.
<span>Water is called the Universal Solvent. Water is regarded as being versatile because of its capability to dissolve many substances which is expected because of its polarity. Water's composition contributes to its solvent abilities, with one side having a negative electrical charge(oxygen) and the other a positive charge(hydrogen) this allows it to attract other molecules thus dissolving them. </span>
Answer:
A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response.
Explanation:
Basically it trains the body by giving it a little expirementation withthe sickness. After that, the body will learn how to properly fight or keep the sickness at bay.
