Answer:
The theory of natural selection was proposed by Charles Darwin, which states the mechanism of biological evolution by explaining <u>adaptation and speciation.</u> There was five observation of the theory of natural selection.
1) The population produces more offspring than there are adults, in each generation.
2) The population does not continue to grow in size.
3) Food and many other resources are limited.
These three observations interfere that individuals compete for resources within a population.
4) Individuals within all populations vary.
5) Many variations are heritable.
He also assumed from these two observations that individuals inherit some characteristics that give a better chance of surviving and reproducing.
These observations and interpretations helped him to propose the theory of natural selection. The theory tells the <u>heritable characteristics in a population change over time</u> <u>become more adapted in generation after generations.</u>
The early signs of a heart attack occur in 50% of patients that have a heart attack according to the Society of Cardiovascular Patient Care. If the early symptoms are noticed the treatment can be administered to prevent damage to the heart as the most heart damages, 85% occur in the 2 hours following the attack.
versatile cas12k-based genetic engineering toolkit (c12kget)
- Genetic modification of micro-organisms is conducive to the selection of high production producers of high-value-added chemicals, but a deficient of genetic tools limits the industrialization of most wild species
- It is very important to develop host-independent gene editing tools which can be used for genetic modification deprived strains.
- A easily found Cas12k-based genetic engineering toolkit (C12KGET) that can result into genomic integration of small parts up to 10 kb in size with up to 100% efficiency in challenging strains.
- By using C12KGET, we accomplished the first example of highly efficient genome editing in Sinorhizobium meliloti, which was successfully solved the question of that industrial strains are difficult to genetically modify, and increased vitamin B12 production by 25%.
- Cas12k can be directly used for transcriptional regulation of genes with up to 92% efficiency due to its naturally inactivated nuclease domain
