Disinfection - destruction of vegetative pathogens; usually on inanimate objects. Antiseptic - agent which prevents bact. contamination and growth; usually on living tissue. Which agent doesn't necessarily work better at higher concentrations? - Alcohol, 70% (goldie lock zone)(60-80% most effective) (Ethyl and Isopropyl) -Alcohol is very effective to resistant to inactivation by organic materials (halogens are not good at this) Name the factors that affect a disinfectant activity. - -Cont...

Peroxisomes are so named because they usually contain enzymes that use oxygen to remove hydrogen atoms from specific substrates in an oxidative reaction that produces H2O2, which is a powerful oxidant and potentially destructive if it accumulates or escapes from peroxisomes. Ribosomes are RNA-protein complexes (nucleoproteins) that are synthesized in the nucleolus and secreted into the cytoplasm through pores in the nuclear envelope called nuclear pore complexes. Lysosomes are saclike s...

IB Biology - Unit 7 - Nucleic Acids HL 100% Solved Antiparallel strands DNA is anti-parellel, meaning the strands run in opposite directions to each other. If one has a 3' at the top the other has a 3' at the bottom, Purines Adenine and Guanine. Pyrimidines Cytosine, Thymine and Uracil Nucleosomes Used for packing DNA, made up of a length of DNA around a group of 8 histones Supercoiling of DNA Winding of DNA strands, this can reduce the size of DNA by 10000x, using nucleos...
