Anorexia nervosa<span> and bulimia nervosa are both eating disorders, but the main difference is that individuals with anorexia have a tendency to skip meals,</span> while individuals with bulimia go through a cycle of binging (overeating) followed by vomiting. People with anorexia are usually extremely underweight and with an unhealthy figure, while the p<span>hysical appearance of people with bulimia can be “normal” or sometimes underweighted.</span>
 
        
             
        
        
        
<h2>DNA Mutations</h2>
Explanation:
<em>    (A) A base-pair deletion</em>
- <em>Insertion or deletion brings about a frame shift that changes the perusing of consequent codons</em> and, hence, adjusts the whole amino acid arrangement that follows the transformation, additions and cancellations are normally more harmful than a substitution in which just <em>a solitary amino corrosive is modified </em>
- DNA changes brought about by mutagens may hurt cells and cause certain illnesses,<em> for example, malignancy</em>
- <em>Instances of mutagens incorporate radioactive substances, x-beams, bright radiation, and certain synthetic compounds</em>
 
        
        
        
Answer:
Explanation:
The double-stranded DNA molecule has the  potential to store genetic information in either strand, although in  most organisms <u>only one strand is used to encode any particular gene</u>.  
The template strand is the non-coding strand. The coding strand of DNA is the non-template (mRNA-like) strand (see attachment).
Thus, genetic  information is expressed by transcription of the non-coding (template) strand  of DNA, <u>which produces an mRNA molecule that has the same sequence  as the coding strand of DNA</u>. Therefore, if a mRNA is transcribed from the non-template strand, the genetic information will not be contained in that strand and it would not produce a correct protein.
