A(n) <u>anticondon </u>is a group of three bases on trna that is complementary to a specific mrna codon. poly-a tail cap codon anticodon
The main function of an anticondon is to form a pair with the condom by mating in order to form an RNA chain, this chain is a sequence of three nucleotides that form a unit of genetic code in a transfer RNA molecule.
<h3>What is molecule?</h3>
It is the union of two or more atoms by chemical bonds, conserving the physical and chemical properties of that substance.
For example: the water molecule is H2O.

Nervous system responds to the environment
Answer:
For a hypothesis to be considered valid, it must make a prediction that scientists can test using a repeatable experiment. If a hypothesis cannot be falsified through experimentation, it cannot be considered part of a valid scientific theory.
Answer:
factory floor!
Explanation:
function:
Contains the organelles; site of most cell activity.
Answer:
True
Explanation:
The epidermis is the outermost layer of the skin, being formed by epithelial tissue. The epidermis is made up of five layers: Stratum corneum, lucid stratum, granular stratum, spinous stratum and stratum basale.
Each layer has specific functions and characteristics:
- Stratum corneum: This is the outermost layer of the epidermis, being formed by dead cells, without nuclei and flattened. The cells have a large amount of keratin and are continually flaking.
- Lucid stratum: Commonly more evident in thick skin (palms and soles), but in regions of the body where the skin is very thin it is not possible to notice its presence. It consists of a layer of flat, eosinophilic and translucent cells.
- Granular stratum: Consists of 3 to 5 layers of flattened polygonal cells with central nucleus and accumulated cytoplasm of basophil granules (keratin-hyaline granules), which will give rise to keratin.
- Spinous stratum: Consists of 5 to 10 layers of flattened cuboid cells with a central nucleus. The cells of this stratum have cytoplasmic projections with keratin filaments, which hold the cells together due to the presence of desmosomes. This whole arrangement gives a "Thorn" aspect to this stratum.
- Stratum basale: This is the <u>germ</u> <u>layer</u>, the deepest layer of the epidermis and in contact with the dermis. This layer is responsible for epidermal renewal, presenting intense mitotic activity. The produced keratinocytes are constantly pushed to the upper layers and increase their keratin production. It takes up to 26 days for a basal cell to reach the stratum corneum, at which point it matures.
