The answer is the letter b
<span> Both of them are nucleic acids. And that is about the only similarity they share. ;)
One of the major differences between the two is that DNA is double-stranded and RNA is single stranded. Also, DNA contains the nucleotide T whereas RNA contains U.
RNA copies the genetic information found within DNA and uses it to assemble protein, as well as ribosomes. Hence, RNA is a crucial part in protein synthesis, being directly involved in it, whereas DNA is indirectly involved in this process.
There are three types of RNA: mRNA (messenger RNA), rRNA (ribosomal RNA) and tRNA (transfer RNA). As far as DNA is concerned, there is only one type of DNA. ;) Another difference.
Also, in some viruses the RNA replaces the DNA but the DNA will never replace the RNA. Yet another difference. </span>

Answer:
Multiple Sclerosis is an inflammatory disease in which myelin sheath of nerve cells of brain and spinal cord are damaged.
Explanation:
Cause:- (Exact cause of inflammation is not known)
- But damage is caused due to attack by autoimmune cells or antibodies against myelin sheath.
Types of tissues attack:-
- Oligodendrocytes and myelin sheath is damaged and stripped away from axon and the process is known as demyelination.
- Myelin sheaths are made up of fatty tissues and help in transmission of electric impulse.
Result of immune system attack:-
- Damaged myelin sheath stop forming whIte matter of central nervous system.
- Hence disrupt coordinating communication between different brain regions.
Signs and symptoms:- vary from person to person
- Diminished eyesight.
- Disrupt motor coordination.
- Weak sensory perception.
- Fatigue and dizziness.
- Speech disorder.
- Muscle weakness and spasticity.
- Difficulty in urination and stool.
Diagnosis and treatment:-
- Diagnosis include MRI T2 findings and cerebrospinal fluid specific oligoclonal bands.
