Answer:
B. introns; exons
Explanation:
Related genes from different organism usually translate to proteins of indispensable functions. This means that the proteins must be similar in terms of amino acids produced. Therefore the coding region must be highly conserved. These can be found in the introns. Conversely, exons are not a part of the coding sequence and therefore not required for translation. These sequences may be less conserved.
 
        
             
        
        
        
Answer:
Gene therapy
Explanation:
Gene therapy can be defined as the methodologies used to modify/restore the expression of target genes and thus cure and treat genetic disorders. Gene therapy approaches consist of delivering specific nucleic acids (either RNA or DNA) in the cells of the individual to be treated. Some of the most important gene therapy approaches include the use of small interfering RNAs (siRNAs) in order to block target gene expression, adenovirus vectors to insert genes into host cells, the use of the CRISPR-Cas9 genome editing system to insert specific sequences by the mechanism of homologous recombination, etc.
 
        
             
        
        
        
Answer: C) The subplate neurons attract the appropriate thalamic axons to the different parts.
Explanation:
Subplate neurons are the first developed neurons can be found in the cortex of mammals. These neurons disappear during the process of postnatal development and due to functional maturation. 
These neurons are sensitive to the injury, when the humans experience cognitive and motor defects. 
These neurons attract the thalamic axons and receive the synaptic inputs through the thalamic axons thus helps in establishing the link between the thalamic axons and the target layer IV. The signals are distributed from the thalamic axons to different parts of the body.
