[How to get it]

First, we collect raw propolis from beehives, then extract by low temperature with ethanol. Filter and concentrate, we get the pure propolis block at 90% to 95%.

[Introduction]

Propolis comes from the substance like natural resin, which is collected by the bees from exudates of plants branches and bud the chemical substances of Propolis are found to be various, such as beeswax, resin, incense lipids, aromatic oil, fat-soluble oils, pollen and other organic matter. Studies have shown that the source of propolis resin in material has three types: bees collected plants secreted fluid, secretion in vivo metabolism of bee, and involvement in the process of forming the material.

We can supply Propolis Extract with food-grade and medicine-grade .The raw materiall is came from non-polluting food grade propolis .Propolis extract was made of high-grade propolis. It maintains the propolis effective ingredients during the procedure of extraction under constant low temperature , taking off the useless substances and sterilization.

[Function]

Propolis is a natural product processed by bees mixed with glutinous and its secretion.

Propolis contains more than 20 kinds of useful flavonoids, rich vitamins, enzymes, amino acids and other microelements, etc. Propolis is called “purple gold” owing to its valued nutrients.

In this video I quickly go over the structure of the DNA and RNA bases and nucleotides, and give some mnemonics for how to remember them.
Molecular structure of DNA and RNA.
The difference between a nucleotide, nucleoside, and base.
nucleotide: base, sugar, one or more phosphates
nucleoside: base and sugar
base: just the base
RNA uses uracil (U) instead of thymine (T). The difference is a methyl group that doesn’t affect base pairing.
The ribose sugar of RNA has a hydroxyl group at the 2′ position that the deoxyribose of DNA lacks. RNA is less stable because of the extra hydroxyl.

The GACT and GACU mnemonics for the DNA and RNA bases
GA: purines
CT/CU: pyrimidines
G base pairs with C
A base pairs with T/U
GC base pairs have 3 hydrogen bonds
AT and AU base pairs have 2 hydrogen bonds, and so are a little weaker.
