Firstly, flanking the open reading frame, all genes contain a regulatory sequence that is required for their expression. In order to be expressed, genes require a promoter sequence. The promoter is recognized and bound by transcription factors and RNA polymerase to initiate transcription.:7.1 A gene can have more than one promoter, resulting in messenger RNAs (mRNA) that differ in how far they extend in the 5' end. Promoter regions have a consensus sequence, however highly transcribed genes have "strong" promoter sequences that bind the transcription machinery well, whereas others have "weak" promoters that bind poorly and initiate transcription less frequently.:7.2 Eukaryotic promoter regions are much more complex and difficult to identify than prokaryotic promoters.:7.3
What does a "weak" promoter sequence do?
bind poorly and initiate transcription less frequently

Following their wedding, the couple leased Windlesham Moor, near Windsor Castle, until 4 July 1949, when they took up residence at Clarence House in London. At various times between 1949 and 1951, the Duke of Edinburgh was stationed in the British Crown Colony of Malta as a serving Royal Navy officer. He and Elizabeth lived intermittently, for several months at a time, in the hamlet of Gwardamanġa, at Villa Guardamangia, the rented home of Philip's uncle, Lord Mountbatten. The children remained in Britain.
Where was Philip stationed during WWII?
British Crown Colony of Malta

Following the adoption of UN Resolution 390A(V) in December 1950, Eritrea was federated with Ethiopia under the prompting of the United States. The resolution called for Eritrea and Ethiopia to be linked through a loose federal structure under the sovereignty of the Emperor. Eritrea was to have its own administrative and judicial structure, its own flag, and control over its domestic affairs, including police, local administration, and taxation. The federal government, which for all intents and purposes was the existing imperial government, was to control foreign affairs (including commerce), defense, finance, and transportation. The resolution ignored the wishes of Eritreans for independence, but guaranteed the population democratic rights and a measure of autonomy.
Who prompted Eritrea to be federated with Ethiopia in 1950?
United States
