It is possible to INCREASE the levels of the protein X by transcription factor binding and epigenetic modifications that induce the expression of the protein-coding gene.
<h3>What are transcription factors?</h3>
Transcription factors can be defined as specific proteins that bind to certain gene regions called promotors in order to promote the transcription of genes.
Moreover, epigenetic modifications such as DNA methylation and histone acetylation may alter the structure of chromatin in order to enable gene transcription.
In conclusion, it is possible to INCREASE the levels of the protein X by transcription factor binding and epigenetic modifications that induce the expression of the protein-coding gene.

Answer:
<h2>a. some RNA molecules can function as enzymes. </h2>
Explanation:
There are two types of genetic material or nucleic acid RNA and DNA. RNA molecule is considered as first information molecule because of several reasons like -
RNA is less stable than the DNA which shows that a less stable form of genetic material gave rise to a more stable form of genetic material.
One of the most important prove is RNA is catalytic which means it can function as enzymes and can catalyze the reaction which is used to copy genetic material i.e RNA. So the correct answer is a.
B organ system contains organs, tissues and cells
Answer:
Given Below :
Explanation:
Swollen lymph nodes usually occur as a result of infection from bacteria or viruses. Rarely, swollen lymph nodes are caused by cancer.
Your lymph nodes, also called lymph glands, play a vital role in your body's ability to fight off infections. They function as filters, trapping viruses, bacteria and other causes of illnesses before they can infect other parts of your body. Common areas where you might notice swollen lymph nodes include your neck, under your chin, in your armpits and in your groin.

Rh proteins; The remainder of the plasma proteins(1%) are regulatory proteins, such asenzymes, proenzymes, and hormones. All blood proteins are synthesized in liver except for the gamma globulins. Separating serum proteins by electrophoresis is a valuable diagnostic tool as well as a way to monitor clinical progress.
