Xigris (Drotrecogin alfa) is not an antibiotic but is approved for the specific indication of sepsis because of its anticoagulant properties.
Xigris (Drotrecogin alfa) is a drug approved by the Food and Drug Administration for the reduction of mortality in adult patients with severe sepsis who have a high risk of death. Xigris (Drotrecogin alfa) is placed under the class of serine proteases and it has anticoagulant, anti-thrombotic, anti-inflammatory, and profibrinolytic properties.
 
        
                    
             
        
        
        
Ans.
The codons show genetic codes, made up of triplet of nucleotides in DNA or RNA that code for specific amino acids. The different codes can code for a same a amino acid. When a substitutional mutation occurs in genetic material, it shows substitution of one nucleotide pair for another and leads to formation of a different codon.
The first mutation that leads to CAU to CAC, it will not show any potential damage as both CAU and CAC codons code for histidine amino acid.
The second mutation that leads to UGU to UGC will also not show any damage to protein as both of these codons code for cysteine amino acid.
The third codon, that results UCU to UUU will cause a potential damage to protein as UUU codes for phenyl alanine (an aromatic, non-polar amino acid) and UCU codes for serine (a polar amino acid). 
Thus, the correct answer is 'option C).' as in a protein, substitution of serine with phenylalanine will lead to change in structure and function of that protein. 
 
        
             
        
        
        
Answer: The correct answer is-
muscle, nervous, connective, and epithelial.    
Tissue can be described as a group of specialized cells that are clustered together to perform particular function.
There are primarily four main types of tissue, which are present in the human body. These tissues are-
Muscle tissue ( assist in locomotion and provides structural support to body).
epithelial tissue ( covers surface of body surface and forms internal lining in most of the organs), 
connective tissue ( such as bones, cartilage, blood) that is abundantly present in the body.
nervous tissue ( helps in the transmission of electrical signals through out body).
