How to choose high-quality summer black grapes

1. Look at the variety. Early-maturing varieties, such as Summer Black and Red Milk, will taste good when they are mature enough. Mid- and late-maturing varieties have not yet reached maturity, and although they have large fruits, they will definitely not taste good.

2. Look at the size of the grapes. The weight of a bunch of high-quality grapes, which experts call the bunch weight, is best at around 1 jin.

3. When choosing grapes, first look at the appearance. The ones with uniform size, fresh and firm stems, full grapes, and a layer of white frost on the surface are of better quality.

4. To taste and see if a bunch of grapes is sweet, you should taste the few grapes at the bottom first. If they are sweet, it means the whole bunch of grapes is good.

Genetic modification is the process of introducing artificially isolated and modified genes into the genome of the target organism, thereby achieving the purpose of transforming the organism. Common methods include microinjection, gene gun, electroporation, liposomes, etc. Genetic modification was initially used to study the function of genes, that is, to introduce foreign genes into the genome of the recipient organism (generally model organisms, such as Arabidopsis or zebrafish, etc.), observe the characteristics exhibited by the organism, and achieve the purpose of revealing the function of the gene. Later, people created genetically modified foods, but because their safety has not been determined, there is still controversy.
