The total number of number of patients using NHS HIV services increased from approximately 17,000 in 1997 to just over 52,000 in 2006. At the same time, the cost of treatment and care increased from Â£104 million in 1997 to Â£483 million in 2006.
A chloroplast is one of three types of plastids, characterized by its high concentration of chlorophyll (the other two types, the leucoplast and the chromoplast, contain little chlorophyll and do not carry out photosynthesis).ne of the main functions of the chloroplast is its role in photosynthesis, the process by which light is transformed into chemical energy, to subsequently produce food in the form of sugars. Water (H 2 O) and carbon dioxide (CO 2) are used in photosynthesis, and sugar and oxygen (O 2) is made, using light energy.
Chloroplasts have their own DNA, often abbreviated as ctDNA, or cpDNA. It is also known as the plastome when referring to genomes of other plastids. Its existence was first proved in 1962, and first sequenced in 1986âwhen two Japanese research teams sequenced the chloroplast DNA of liverwort and tobacco.hloroplasts have their own DNA, often abbreviated as ctDNA, or cpDNA.
