Ice Wines From Around the Globe. No matter what part of the globe theyâre from, ice wines are treasures to be savored. Itâs been months since the traditional grape harvest has ended, but in ice-wine country, row upon row of pristinely ripened grapes dangle precariously on the vines. 1  Through Decemberâand sometimes into January or Februaryâthe grapes will shrivel and freeze, concentrating their sugars, acids and fruit essences.
A bacteriophage is a virus which infects bacteria. These viruses typically cause their hosts to die as a result of infection, which makes bacteriophages of great interest to the medical community and to scientists who cultivate bacteria. bacteriophage is a virus which infects bacteria.

The term is derived from bacteria and the Greek: ÏÎ±Î³Îµá¿Î½ (phagein), to devour. Bacteriophages are composed of proteins that encapsulate a DNA or RNA genome, and may have relatively simple or elaborate structures. Their genomes may encode as few as four genes, and as many as hundreds of genes.Phages replicate within the bacterium following the injection of their genome into its cytoplasm.acteriophages may have a lytic cycle or a lysogenic cycle, and a few viruses are capable of carrying out both. With lytic phages such as the T4 phage, bacterial cells are broken open (lysed) and destroyed after immediate replication of the virion.
