<em>The First one is 2, The answer to question 2 would be: Gene Splicing or Cloning</em>
<em>First, the gene that makes insulin is cut from human cells. After having the insulin gene, the scientist will put it inside bacteria so the bacteria will produce human insulin. This was called gene splicing. </em>
<em>Then the bacteria have insulin genes, the bacteria will be cloned to make multiple colonies of same bacteria. This phase called cloning. </em>
<em>and the last one 2, mitochondria.</em>

Answer:
For DNA replication to occur, the two chains that form it must be separated, each with a specific base sequence that serves as a template for the coupling of complementary nitrogen bases, that is, adenine with thymine and cytosine with guanine, attending to the base pairing rules.
Explanation:
Base pairing rules is the way in which nitrogen bases are matched in the double strand of DNA during replication, which occurs by <u>binding a purine with a pyrimidine</u>.
The DNA contains sequences of 4 nitrogen bases, two purines and two pyrimidines. Pyrimidines are cytosine and thymine, while purines are adenine and guanine. Adenine should bind thymine and cytosine with guanine, according to the rule. When the bases are paired, they form hydrogen bonds between them, two for Adenine-Thymine and three for Cytosine with Guanine.
The relationship between the two strands of DNA is that one complements the other, due to the complementarity of their bases.
<u>DNA replication is semi-conservative</u>, since by separating the two chains one serves as a template for a new chain to be formed, by pairing complementary bases. The final result is two DNA molecules, each with an original chain and new one.

Answer:
Multiple Sclerosis
Explanation:
Multiple sclerosis (MS) is the most common neurodegenerative and demyelinating inflammatory disease in adults between 18 and 35 years of age and is the second leading cause of neurological disability in young adults. This pathology is considered an organ-specific autoimmune disorder, characterized by multiple focal areas of demyelination called plaques or lesions, which are accompanied by different degrees of gliosis, inflammation and neuroaxonal damage. It usually manifests itself in coordination and balance problems, muscle weakness, difficulties in thinking and memorizing and sensations of numbness, as well as other symptoms. Diagnosis of MS is based on a clinical evaluation in which all symptoms, as well as the signs (overactive reflexes, incoordination, weakness of specific muscle groups, etc.) of the disease are documented. Magnetic resonance imaging (MRI) is used to obtain cross-sectional images of the brain and spinal cord, which can detect the small areas of inflammation and scarring in the brain typical of MS.Lumbar puncture is an analysis of a sample of cerebrospinal fluid (CSF), which has the function of cushioning the brain and spinal cord, to evaluate the abnormalities that occur in patients with MS. The most common CSF abnormality found in 80-90% of MS patients is an increase in the number of cells and proteins of the immune system (immunoglobulins), suggesting inflammation or a strong immune response. This test is particularly useful to diagnose patients who experience a slow and progressive decline in their functions without exacerbation pictures; that is, people with primary progressive multiple sclerosis, especially when no abnormalities are detected in the MRI images of the brain. CSF evaluation can also be used to exclude infections difficult to distinguish from multiple sclerosis.
Answer: Gregor Mendel definitely did study heredity, as stated by the other answerer, but it is not technically correct. Mendel is the founding father of genetics, so he studied genetics, a branch of biology that he formed.
Explanation: In an experimental botanical garden, Mendel cross-bred pea plants and studied all of their phenotypes and genotypes. Through these studies, he established the rules of heredity and inheritance, which led to the creation of the field of genetics. Thus, he founded and studied genetics.
