If the trait for tall is dominant and trait for yellow is recessive: TTyy and TTyy, Ttyy and TTyy

If the trait for tall is recessive and trait for yellow is dominant: ttYY and ttYY, or TtYy and TTYY

How does replication of the lagging strand of DNA compare with replication of the leading strand?
Natali5045456 [20]

Answer: The correct answer is- B) Okazaki fragments are made on the lagging strand but not on the leading strand.

DNA replication is a biological process in which two identical replica of DNA are produced from single original DNA molecule through an enzyme called DNA polymerase.

The strands of double helical DNA are first separated ( with the help of helicase enzyme) so that the template DNA strands are exposed. DNA is synthesised in 5' to 3' direction.

Leading strand ( whose template strand is 3' to 5') is synthesized in continuous manner as DNA polymerase moves along the direction of replication folk.

Whereas lagging strand ( whose template strand is 5' to 3') is synthesized in a discontinuous manner as it requires multiple primers to synthesise the DNA. It generates small fragments of DNA called okazaki fragments.

ESTOS ALIMENTOS DULCES AZUCARADOS NO SÓLO SON MALOS PARA LA SALUD,SINOQUE YANDIEN PUEDEN SER E________.AMENUDO SE DISFRASAN CON
Semenov [28]

La respuesta correcta para esta pregunta abierta es la siguiente.

Desafortunadamente, no anexaste opciones o incisos para responder la pregunta. Sin embargo, podemos comentar lo siguiente.

ESTOS ALIMENTOS DULCES AZUCARADOS NO SÓLO SON MALOS PARA LA SALUD, SINO QUE TAMBIEN PUEDEN SER ENGAÑOSOS. A MENUDO SE DISFRAZAN CON NOMBRES QUE PUEDEN SER SABROSOS.

Es muy importante que seas cuidadoso con los alimentos que consumes como parte de tu alimentación. Muchas empresas, a través de sus marcas, comparten publicidad engañosa para atraer más clientes bajo la promesa de alimentos sabrosos y nutritivos. Y la verdad es que no. Te están engañando.

No hay nada como basar tu dieta diaria en frutas, verduras y un equilibrio entre proteínas, carbohidratos, azúcares naturales y grasas.

Si es necesario, consulta a tu médico o a un nutriólogo para que te expliquen qué tan malo pueden ser los alimentos con muchos químicos.

¿Son sabrosos? Sí, pero también están llenos de sal, grasas, azúcares en excesos que le hacen mucho daño a tu salud.

En México ya existe una ley que obliga a todos los productos colocar unas etiquetas de color negro con blanco en todos los productos con la leyenda: "exceso de sodio," "exceso en grasas," exceso en azúcar."

Esto, con el propósito de que la gente se entere antes de comprarlos.
