Answer:
Nucleic Acids
Explanation:
Nucleic acids are DNA and RNA and they are the molecules responsible for containing the genetic material of all living beings. Thus, DNA and RNA are the molecules responsible for establishing the variability and different characteristics between dog breeds, through the genetic information that each of them houses.
In this case, among the options given in the question above, we can confirm that if Allen has studied the genetic material of dogs to better understand why there are so many different breeds, he must have studied nucleic acids.
Answer:
These facts are true and disturbing
Explanation:
Genetics is a discipline that has advanced incredibly in the last years. For example, by using the versatile CRISPR-Cas9 genome editing system, we are now able to insert literally any sequence into a given genome in vivo. The CRISPR-Cas9 is a technology that can be used in a regular molecular biology laboratory. It is expected this technique will enable in the near future to correct genetic disorders that have plagued mankind since times immemorial. However, genomic technologies like that could be used by malignant persons to hurt innocent people, thereby it is imperative that countries regulate their use.
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.

It's important because we need the scientists to discover where it is. the lokiarchaeota is a main cause for infections, and diseases, and if we identify it, and study it, we may know how to cure certain diseases, and how to prevent them.
