The structure of nucleotide monomers. A nucleotide is made of a nucleobase (also termed a nitrogenous base), a five-carbon sugar (either ribose or 2-deoxyribose) depending on if it is DNA or RNA, and one or, depending on the definition, more than one phosphate groups. nucleotide is made of a nucleobase (also termed a nitrogenous base), a five-carbon sugar (either ribose or 2-deoxyribose) depending on if it is DNA or RNA, and one or, depending on the definition, more than one phosphate groups.
The most common image file formats, the most important for cameras, printing, scanning, and internet use, are JPG, TIF, PNG, and GIF. 1  JPG is the most used image file format. 2  Digital cameras and web pages normally use JPG files-because JPG heroically compresses the data to be very much smaller in the file.
There are many file extensions for image files, but the most popular are .JPG (or .JPEG), .GIF, .PNG and .TIF. In addition to these file types, many digital cameras save in a format known as .RAW, or a brand-specific format.
