Answer:
Bacteria do not possess the tendency to withdraw sequences of introns from a gene, thus, if the gene for the human growth hormone were transcribed, it would translate into a non-functional protein.
When the expression of a gene takes place in eukaryotes, the budding mRNA comprising introns are removed consequently at the time of post-translational processing to produce mature mRNA. Also, the human growth hormone is produced by the pituitary gland in the form of a pre-hormone comprising a leader peptide of about 20 amino acids in length, which need to get removed post-translationally to produce a mature functional protein.
Bacteria do not possess the biochemical machinery either to effectively withdraw the leader peptide after translation or to splice out the introns. Thus, when an unchanged human growth hormone is cloned, the bacteria cannot produce the functional human growth hormone.
Answer:
Selective breeding is used to promote the benefits of both animal and plant breeding inheritance. It is essentially done by controlled breeding. However, it has its own set of disadvantages, like any other agricultural method-although it is supposed to offer benefits to society. If you want to selectively breed your crops and cattle, weigh them down and decide whether that’s a good way for you.
No company patent is required.Anyone working in farming can start breeding selectively whenever they want. It is a way for him to create more profits every year, as he can grow animals and plants with different characteristics such that they can be generated over centuries, which is good for businesses. And since he is free, he only needs to be knowledgeable and well equipped in the process to achieve the best result.
It makes higher profit possible.Selective breeding encourages more beneficial plant and animal characteristics for farmers. If they have selectively bred cows, for example, these animals can produce more milk than the typical cows and the gene can be transferred to their descendants. If the method is used on crops, more than the typical ones will also be grown. Promoting these advantages will certainly increase their product’s market value. Selective breeding is certainly an perfect choice for farmers who are in a major company.
