Arte-miy333 [17]
<h3>Briefing:</h3>

In Drosophila, the eyeless gene is necessary for the development of eyes. Given that it encodes for a homeodomain, its protein may have a role as a transcription factor that binds DNA in a specific sequence. In situ hybridization can be used to study the gene's mRNA expression pattern, and immunological methods can be used to study the protein.

A. Since the eyeless gene in Drosophila encodes for a homeodomain, one potential use for its protein is as a DNA-binding transcription factor that binds to specific DNA sequences.

B. As implied by its function, the eyeless gene should be expressed in the Drosophila cells in charge of eye formation. In situ hybridization of the gene's mRNA expression is one potential test to find the gene. The protein can also be seen via a variety of immunological and staining methods. It is possible to do gene deletion experiments to see if Drosophila will retain its eyes or go blind. Additionally, genetic engineering can determine whether the eyeless gene expressed in other organs can result in the creation of eyes.

C. Transgenic tests can be used to determine whether the Small eye and Aniridia genes function similarly to the fly eyeless gene. Since both of these function as master switches for the genes that create eyes, it is possible to transfer the mouse Small eye gene into Drosophila to observe whether it is expressed. These, however, are simply Drosophila eyes and not comparable to mouse eyes.

<h3>Describe DNA:</h3>

All known organisms, including many viruses, require deoxyribonucleic acid, a polymer comprised of two polynucleotide chains that coil around one another to create a double helix, to develop, function, grow, and reproduce. DNA and ribonucleic acid are examples of nucleic acids.

Art [367]

The correct answer is option A, that is, development often causes habitat fragmentation, which can threaten biodiversity.

Fragmentation is usually illustrated as a reduction in some of all the kinds of natural habitats in a landscape, and the differentiation of a landscape into smaller and more isolated segments. With the development of the fragmentation process, the ecological influences will modify.  

Fragmentation can be a result of natural procedures like floods, fires, and volcanic activity, but it is more generally caused due to human activities like an increase in the number of roads, housing developments, shopping centers, and parking lots.  

With the enhancement in human activities, the effect of fragmentation become more. Eventually, it results in the devastating influences on the local species, a complete modification to the landscape, and the loss of the region's wilderness heritage.
