A(n) anticondon 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.

Why was the Euglena green in color? What is the name of the specialized body structure that is located at the base of the tail?

Leni [432]

Euglena is green in color because of the chlorophyll that is contained in the chloroplast of that organism and the body structure that is located at its base is known as flagellum .

Explanation:

Euglena are species that are found in the fresh and salt water. They are abundantly found in inland waters where they manage themselves to bloom in large amount and color the water surface of ditches and ponds green.

This green color which them form are mainly due to the chlorophyll that is contained in the chloroplast of the organism. chlorophyll is known to be the pigment that is responsible for the green color.It is the cause for the green color in this case too.

Euglena contains a specialized body structure which is located at the base of the tail by which it manages to move.

This specialized structure is known as Flagellum.

The last time you saw the sisters pictured above, you considered how different protein molecules in their cells could lead to di

Andrew [12]

Answer:

recombination and independent segregation of chromosomes during meiosis

Explanation:

Recombination and independent segregation of chromosomes represent the two most important meiotic mechanisms by which sisters from the same parents can inherit different gene variants and therefore look very different from each other:

1- Independent assortment (segregation) of chromosomes: during meiosis, homologous chromosomes are randomly distributed in daughter cells (which will give rise to the gametes), and therefore separate independently of each other. It is for that reason that gametes have unique combinations of chromosomes, which increases genetic variation.

2- Recombination, also known as crossing over, refers to the exchange of chromosome segments between non-sister chromatids during meiosis. This mechanism is well-known to produce new gene variants (alleles) in the daughter cells. In consequence, recombination also increases the genetic variation of the resulting gametes that will produce offspring (in this case, different sisters).
