Answer:
Option (I) and (IV).
Explanation:
Fatty acids may be defined as the carboxylic acid that contains the long aliphatic chain. Fats are generally of two types - saturated fatty acid and  unsaturated fatty acid.
The fatty acids are generally synthesized in the two carbon units. This helps in the proper synthesis of fat. The fatty acids that are most common in plants and animals are palmittic acid or the fats that contain  C16 and C18 species predominate.
Thus, the correct answer is option (I) and (IV).
 
        
             
        
        
        
Laurentia<span> (</span>North American Craton<span>) is a large continental </span>craton<span> that forms the ancient geological core of the </span>North American<span> continent. Many times in its past, Laurentia has been a separate </span>continent<span> as it is now in the form of North America, although originally it also included the cratonic areas of </span>Greenland<span> and also the northwestern part of </span>Scotland, known as theHebridean Terrane<span>. During other times in its past, Laurentia has been part of larger continents and </span>supercontinents<span> and itself consists of many smaller </span>terranes<span> assembled on a network of Early </span>Proterozoic orogenic<span> belts. Small </span>microcontinents<span> and oceanic islands collided with and sutured onto the ever-growing Laurentia, and together formed the stable </span>Precambriancraton seen today.
        
             
        
        
        
Answer:
During the process of translation, the codon UAC sets up the open  reading frame in the mRNA (messenger Ribonucleic acid). The codon UAC corresponds to ATG in the DNA. It codes for the amino acid methionine.
Explanation:
The determination of the open reading frame is important in the process of translation and protein formation. The start and stop codons determine the open reading frame. In DNA (deoxyribonucleic Acid), there are typically six reading frames. The correct frame is determined and the translation is started. 
The ATG codon in the DNA sets the reading frame in most of the eukaryotes. Different frames can be started by beginning with either 'A', 'T', or 'G'.
