finlep [7]

Answer:

GG, Gg, Gg, gg

Homozygous green – GG

Heterozygous green – Gg

Homozygous yellow - gg

Explanation:

It is given that allele for green seed pods (G) is dominant to the allele for yellow seed pods (g) which means that if “G” and “g” occur together, a trait associated with G will be expressed.  

The genotype of the true breeding Green plant is “GG”  

The genotype of the true-breeding yellow plant is “gg”  

F1 generation cross  

GG * gg

Offspring produced from F1 generation are – Gg, Gg, Gg, Gg

In f2 generation offspring of F1 generation are crossed among each other.  

So the offspring produced in F2 generation are  

Gg * Gg

GG, Gg, Gg, gg

Homozygous green – GG

Heterozygous green – Gg

Homozygous yellow - gg

Las células en los tejidos epiteliales están fuertemente unidas a la lámina basal. ¿Qué tipo de proteínas están involucradas en
Sveta_85 [38]

Answer:

integrinas y lamininas

Explanation:

Las integrinas son glucoproteínas implicadas en el anclaje de las células epiteliales a la matriz extracelular. Las células epiteliales tienen en su base proteínas integrinas que se unen a otras proteínas tales como vitronectina, fibronectina, colágeno y laminina. De este modo, las integrinas se asocian con lamininas de la lámina basal. Las lamininas son otra clase de glucoproteínas las cuales conforman la lámina basal y contienen sitios de unión para integrinas. A partir de esta asociación las células epiteliales pueden adherirse a la membrana basal y mantener su orientación dentro de un tejido. Estas uniones son fundamentales para que las células epiteliales puedan soportar fuerzas y son críticas durante el desarrollo apropiado (ontogenia) del organismo.
