Article: The initial prototype shown in May 2005 featured two HDMI ports, three Ethernet ports and six USB ports; however, when the system was shown again a year later at E3 2006, these were reduced to one HDMI port, one Ethernet port and four USB ports, presumably to cut costs. Two hardware configurations were also announced for the console: a 20 GB model and a 60 GB model, priced at US$499 (€499) and US$599 (€599), respectively. The 60 GB model was to be the only configuration to feature an HDMI port, Wi-Fi internet, flash card readers and a chrome trim with the logo in silver. Both models were announced for a simultaneous worldwide release: November 11, 2006, for Japan and November 17, 2006, for North America and Europe.

Question: Why might Sony have reduced the number of ports on the PlayStation 3 before production?

Article: Zinc serves a purely structural role in zinc fingers, twists and clusters. Zinc fingers form parts of some transcription factors, which are proteins that recognize DNA base sequences during the replication and transcription of DNA. Each of the nine or ten Zn2+ ions in a zinc finger helps maintain the finger's structure by coordinately binding to four amino acids in the transcription factor. The transcription factor wraps around the DNA helix and uses its fingers to accurately bind to the DNA sequence.

Question: What role does zinc play in fingers, twists and clusters?
Ans:
structural
