ested in studying in this chapter the bacterial viruses, bacteriophages, or just phages (Greek: eating) are exclusively genetic material surrounded by a protein coat. Bacteriophages are usually classi ed rst by the type of genetic material (nucleic acid) they have (DNA or RNA, single- or double-stranded), then by structural features of their protein surfaces (capsids) such as type or symmetry and number of discrete protein subunits (capsomeres) in the capsid, and general size. Most bacteriophages are complex, like T2 ( g. 7.1), or made up of a headlike capsule like T2 without the tail appendages, or lamentous. Most contain double-stranded DNA. Bacteriophages are obligate parasites; outside of a host, they are inert molecules. Once their genetic material penetrates a host cell, they can take over the metabolism of that cell and construct multiple copies of themselves. We will discuss details of this and alternative infection

plate. Bacteria were streaked on the petri plate with an inoculation loop a metal wire with a looped end covered with bacteria. Streaks began at the upper right and continued around clockwise. With a heavy inoculation on the loop, bacterial growth is con uent. Eventually, only a few bacteria are left; they form single colonies at the upper left. (Photo by Robert Tamarin.)

This is known as a ternary expression, in which n < 16 is an initial test The symbol then indicates that if the result of the test is true then the value immediately following the should be returned Otherwise the value following the : should be returned In this example, that means that values of n that are lower than 16 will result in the string '0' being returned, while values of n that are 16 and above result in ' ' being returned The reason for this is that this plug-in will mostly be used by code that wants to create color triplets for setting a color These triplets are made up of three groups of two hexadecimal characters, like these: FF0088, 112233, CCCCCC, and so on Each of these stands for hexadecimal FF (256 decimal) shades of the colors red green and blue For example, FF0088 means the intensity values for the given color should be FF red, 00 green and 88 blue, in hexadecimal Therefore, going back to the code segment, if n is less than 16 it becomes a single digit in hexadecimal (a number between 0 and F), and in such cases a leading 0 is added to pad the number up to the required two digits Having padded the number with a 0 (if necessary), the number n is then passed to the JavaScript toString() function with an argument of 16, like this code segment:
