- Stealth Mosquitoes? - Biology Stack Exchange
Have mosquitoes become silent and invisible, or am I losing my senses of hearing and sight? This summer I have seen no mosquitoes and have only heard two of them, very quiet, as I sat on my sofa la
- How is the size of a gene defined? - Biology Stack Exchange
Is there an agreed definition as to how many nucleic acid bases constitute a gene? If not, why not? I'm not sure I understand how the exact sizes of genes are defined
- Are there any papers that give examples of what is a high and low . . .
No High and low gene expression are not absolute concepts, as the poster himself would seem to recognize in his speculations about different types of protein In science you can only talk about “high” and low in relation to some reference normal situation, and this means making a measurement on some appropriate control What control is appropriate will depend on your biological system
- Mammal body density - Biology Stack Exchange
Human body density is approximately 1 kg l (same as fresh water) - which is not surprising (at first) given that we are 70% water, and is surprising (on a second thought), given that the other 30%
- dna - qPCR precipitation - Biology Stack Exchange
I have performed DNA precipitation using two methods on an amplified 194 bp PCR product: using a PEG method with just cold 80% ethanol PEG worked much better for me Can the same methods be appli
- Absorption ratios 260 280 and 260 230 for RNA - Biology Stack Exchange
I extracted RNA from different cell lines, an I want to perform reverse transcription and then PCR To get good results, in which range should the absorption ratios 260 280 nm and 260 230 nm be? An
- Why are so few foods blue? - Biology Stack Exchange
Although blue foods exist, they're rare enough compared to other foods for food preparers to use blue plasters as a convention The natural colour of a given food is due to pigments that have some
- Do spiders learn how to build webs? - Biology Stack Exchange
Spiders’ ability to weave webs is a classic example of an innate or instinctual behavior They do not learn to make webs The earliest English-language scientific publication that I can find to back this claim is Porter 1906 1, which focuses on variation in the webs of Orb-weaving spiders: The web of the Orb-weaving Spiders has long been one of the classical examples of animal instinct It
