Arctic Sea Ice 2008 The polar ice caps have been shrinking in summer and expanding in winter for millions of years. But in the last 3 decades, the arctic sea ice at the end of each summer's melt has been getting steadily smaller. Turkish President on miners' deaths: 'Our pain is so big' 4.4 Reducing nutrient availability Once nutrients are in an ecosystem, it is usually much harder and more expensive to remove them than tackle the eutrophication at source. The main methods available are: precipitation (e.g. treatment with a solution of aluminium or ferrous salt to precipitate phosphates); removal of nutrient-enriched sediments, for example by mud pumping; and removal of biomass (e.g. harvesting of common reed) and using it for thatchi 2.4.1 Estuarine species Nutrient runoff from the land is a major source of nutrients in estuarine habitats. Shallow-water estuaries are some of the most nutrient-rich ecosystems on Earth, due to coastal development and the effects of urbanization on nutrient runoff. Figure 2.19 shows some typical nitrogen pathways. Nitrogen loadings in rainfall are typically assimilated by plants or denitrified, but septic tanks tend to add nitrogen below the reach of plant roots, and if situated near the coast or rivers can lead to 8.3 Chromosome distribution within the nucleus DNA from any one particular chromosome is a single chain, many millions of bases long, and this chain is attached to a scaffold structure. It is not surprising then, that if we examine the interphase nucleus, each chromosome is seen to fill a localised area. This localised distribution of individual chromosomes is illustrated in Figure 42 with an examination of human chromosomes within the interphase nucleus. In these examples, special DNA probes have been used to detect the location of the e 8.2 Chromosome scaffolds Most of the chromosomal DNA chains within the interphase nucleus are believed to be held on a scaffold or backbone structure made from various proteins, with loops of between 20 and 200 kb extruding from attachment sites. This chromosome structure is shown schematically in Figure 40. The scaffold, as well as permitting further compaction, serves to bring the DNA together in organised regions. There are many different protein components of these scaffolds, amongst them DNA topoisomerases. 8.1 Introduction The average human cell has around two metres of DNA within its nucleus. In the interphase nucleus, in which transcription and replication are going on, this DNA is packaged into nucleosomes that are variably compacted, through association with H1, into larger 30nm fibres. In fact, the average nucleus most likely contains DNA with a continuum of chromatin configurations, ranging from highly open 10 nm fibres, through to 30 nm fibres and fibres that are even more tightly packed together, call Core histone tail modification regulates DNA compaction What effect would neutralising the positive charges on the octamer N-terminal tails have upon the compaction of DNA by H1?
