Answer:

Positively charged ions

Explanation:

Histones are a group of proteins with a N-terminal end of an amino acid, that binds to the DNA in the nucleus helping it to condense into Chromatin. DNA wraps around a core of proteins to initially form the NUCLEOSO ME structure, which is the basic subunit of Chromatin. Each nucleosome is made up of DNA coiled around two copies (2) of proteins- H2A, H2B, H3 and H4, to form a set of eight proteins called histone octamer.

Due to the phosphate group (PO4-) embedded in the DNA molecule, they assume a negative charge. The positively charged ions of the N(C) terminal end of histones which arise from the amino acid group they contain allows it to bind tightly to negatively charged DNA i.e. the more positively and negatively charged the histone and DNA are respectively, the tighter the binding.

Due to this property, the proteins that binds to DNA in E.coli, should possess a positive charge in similarity to histones in eukaryotes.

The answer is b. For example, nuclear fusion in the sun (an exergonic process) releases energy as light and heat, and powers the initial steps of photosynthesis (an endergonic process).

silver oxide coatings with high silver-ion elution rates and characterization of bactericidal activity
GenaCL600 [577]

The manufacture and characterisation of silver oxide films for application as bactericidal coatings are described in the research.

  • There are reports on the synthesis parameters, dissolution/elution rate, and bactericidal effectiveness.
  • Reactive magnetron sputtering was used to generate the synthetic conditions necessary to produce AgO, Ag2O, or combinations of AgO and Ag2O on surfaces.
  • All of the examined bacterial strains are hampered from growing by the coatings, which exhibit good adherence to numerous substrate materials.
  • <em>Escherichia coli</em> and <em>Staphylococcus aureus</em> can be killed by the coatings, which also show a distinct zone of inhibition against bacteria growing on solid media and the capacity to quickly stop bacterial growth in planktonic culture.

What do you think is useful about knowing how to read a pedigree
Jobisdone [24]

Answer:

Knowing how to read a pedigree allows you to track through the family history and how a condition is passed down, if it is genetic. It allows you to tell if the condition is sex-linked, autosomal, dominant, or recessive. It also allows you to see the family and what occurs in the family, such as marriages, miscarriages, and other relationships.
