Why is it important for both eukaryotic and prokaryotic cells to go through cell division?
Naya [18.7K]

Answer:

La división celular es una parte muy importante del ciclo celular en la que una célula inicial se divide para formar células hijas.1​Debido a la división celular se produce el crecimiento de los seres vivos. En los organismos pluricelulares este crecimiento se produce gracias al desarrollo de los tejidos y en los seres unicelulares mediante la reproducción asexual.

Los seres pluricelulares reemplazan su dotación celular gracias a la división celular y suele estar asociada con la diferenciación celular. En algunos animales la división celular se detiene en algún momento y las células acaban envejeciendo. Las células senescentes se deterioran y mueren debido al envejecimiento del cuerpo. Las células dejan de dividirse porque los telómeros se vuelven cada vez más cortos en cada división y no pueden proteger a los cromosomas como tal.

Las células hijas de las divisiones celulares, en el desarrollo temprano embrionario, contribuyen de forma desigual a la generación de los tejidos adultos.

In beans the pod texture and growth form genes are located on different chromosomes. There are two varieties of beans in a farme
irina1246 [14]

Answer:

a. Genotype in F1 - TtBb

   Phenotype in F1 - tough pods, bush-type growth

b. Proportion of F2 that are heterozygous for bush-type growth form = 5/8

c. Proportion of the F2 with tender pods =  1/4

d. Proportion of F2 that are heterozygous for growth form and have tender     pods = 1/8

Explanation:

Since the two traits are located on different chromosomes, they will independently assort during gametes formation. T is dominant over t and B is dominant over b.

Two true-breeding varieties were crossed at the beginning of the program:

TTBB   x   ttbb

All F1 plants will have the genotype TtBb with tough pods and bush-type growth form.

Advancing the cross to F2:

TtBb   x   TtBb

Progeny

1 TTBB   -   tough pods, bush-type

2 TTBb     -  tough pods, bush-type

2 TtBB    -   tough pods, bush-type

4 TtBb     -   tough pods, bush-type

1 TTbb     -    tough pods, climbing-type

2 Ttbb     -    tough pods, climbing-type

1 ttBB       -    tender pods, bush-type

2 ttBb     -      tender pods, bush-type

1 ttbb      -      tender pods, climbing-type

<em>Proportion of F2 that are heterozygous for bush-type growth form = 10/16 = 5/8</em>

<em>Proportion of the F2 with tender pods = 4/16 = 1/4</em>

<em>Proportion of F2 that are heterozygous for growth form and have tender pods = 2/16 = 1/8</em>
