Article: A typical protein-coding gene is first copied into RNA as an intermediate in the manufacture of the final protein product.:6.1 In other cases, the RNA molecules are the actual functional products, as in the synthesis of ribosomal RNA and transfer RNA. Some RNAs known as ribozymes are capable of enzymatic function, and microRNA has a regulatory role. The DNA sequences from which such RNAs are transcribed are known as non-coding RNA genes.

Question: What sort of synthesis occurs when the RNA molecules are the actual functional products?
Ans: the synthesis of ribosomal RNA and transfer RNA

Article: The first attempts to use standard-frequency single-phase AC were made in Hungary as far back as 1923, by the Hungarian Kalman Kando on the line between Budapest-Nyugati and Alag, using 16 kV at 50 Hz. The locomotives carried a four-pole rotating phase converter feeding a single traction motor of the polyphase induction type at 600 to 1,100 V. The number of poles on the 2,500 hp motor could be changed using slip rings to run at one of four synchronous speeds. The tests were a success so, from 1932 until the 1960s, trains on the Budapest-Hegyeshalom line (towards Vienna) regularly used the same system. A few decades after the Second World War, the 16 kV was changed to the Russian and later French 25 kV system.

Question: What frequency did the line of Hungarian rail system used in 1923?
Ans: 16 kV at 50 Hz

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: What color is the logo on the 60 GB PS3?
Ans:
silver
