Apply, yelenots. The skills identified in a job advert are for the ideal candidate, and depending on what they are, the combination where all applicants can do all the required tasks straight away may not be realistic. There will be some key things you must have, and others which are "desirable". You can always say in your application "I can do this and this and this in the job description - as yet I have no experience in this, but I am very willing to learn and to expand my skills". Go for it.
