Text SolutionText solutionverified iconVerified

Heterotrophic bacteria are microorganisms which survive by deriving their energy using organic matter from other sources rather synthesizing their own organic matter. The Heterotrophic bacteria have several economic applications; Lactobacillus and Streptococcus are widely used for the production of milk products like curd and cheese. Streptomyces is a genus of Gram-positive bacteria with the ability to produce bioactive secondary metabolites such as antifungals, antivirals, antitumoral, anti-hypertensives, and mainly antibiotics and immunosuppressives. Many different kinds of heterotrophic bacteria are used for sewage treatment. Some heterotrophic bacteria like Alcanivorax or Methylocella Silvestris have an important applications in bio-remediation (cleaning the oil spills). 
Archaebacteria are a group of prokaryotes which live under very harsh and hostile conditions. Since the enzymes from these organisms can survive harsh conditions they have many industrial applications in biotechnology; Many of the thermostable enzymes used in the manipulation of DNA are derived from Archaebacteria, Methanogens of the Archaebacteria are mainly involved in the biogas production.

Here are the names of several Drosophila genes; many of them refer to mutations that we use in the lab. Body color: yellow (y), black (b), ebony (e). Wings: apterous (ap), vestigial (vg), miniature (m). Eye color: white (w), sepia (se). Eye size/shape: Bar (B), lozenge (lz). Bristles: forked (f). For any three of them, find out the following: Length of protein sequence; Chromosome # and arm and coordinate in map units; Protein function; # of exons and introns; Are there any isoforms? If yes, describe them. (Alternative promoter, alternative splicing pattern…) Run Protein BLAST. What is the nearest paralog (=name of the gene)? Determine the % of amino acid sequence identity. Find the nearest ortholog in Homo sapiens (=name of the gene). Determine the % of amino acid sequence identity.
