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.
Image files that employ JPEG compression are commonly called JPEG files. The most common file extension for this format is .jpg, though .jpeg, .jpe, .jfif and .jif are also used. It is also possible for JPEG data to be embedded in other file types, such as TIFF format images.JPEG/JFIF is the format most used for storing and transmitting photographs on the World Wide Web.PEG should not be confused with MPEG (Moving Picture Experts Group) which produces compression schemes for video. JPEG itself specifies both the codec, which defines how an image is compressed into a stream of bytes and decompressed back into an image, and the file format used to contain that stream.
