HIV can be treated via gene therapy by inducing mutations that restore the normal genome sequence.
<h3>
What is gene therapy?</h3>
Gene therapy is a revolutionary technique used in molecular biology to restore the expression of defective genes that suffered mutations.
Gene therapy involves modifying the nucleotide (DNA) sequence in order to correct the production of defective proteins associated with disease states.
Moreover, mutations due to HIV are a consequence of the insertion of this retrovirus in the host genome.
In conclusion, gene therapy is able to treat HIV by inserting gene regions that restore the normal nucleotide sequence.

Answer: DF508 mutation. A Genetic, Hereditary, Autosomal and Recessive Mutation.
Explanation:
Cystic fibrosis (CF) is a recessive autosomal lethal disease, it is most common on Caucasoid populations. Its diagnosis is suggested by the clinical features of chronic obstructive pulmonary disease, persistent pulmonary colonization (particularly with mucoid Pseudomonas strains), meconium ileus, pancreatic insufficiency with or familiarity history of the disease. The FC gene is large, with about 250 Kb of genomic DNA, 27 exons representing about 5% of genomic DNA; encodes a 6.5 kb transcribed mRNA. This mRNA is transcribed into a protein of 1480 amino acid called CFTR (Regulator Transmembrane Conductance Cystic Fibrosis). When a three-base pair deletion, adenosine-thymine-thymine (ATT) identified in the CFTR gene, exon 10, it results in the loss of a single amino acid phenylalanine at position 508 of the protein. This mutation is called DF508; “D” stands for deletion and “F” for phenylalanine amino acid.
Answer:
- Fossil record
- Geography
- Embryology
- Comparative anatomy
Explanation:
The four types of evidence for evolution upon which Darwin based his ideas were:
1-The geographic distribution of related species. The theory of evolution states that species evolve in geographic areas that were colonized by their ancestors.
2-The fossil record shows successions of organisms through time
3-Embryology: animal embryos in related species are very similar in the early stages of development but differentiate as they grow, thereby suggesting these species evolved from a common ancestor.
4-Comparative anatomy demonstrates physical and structural similarities between species. The species share anatomical similarities because they descend from a common ancestor (i.e., presence of homologies).
