Complete el cuadro de Punnett que muestra un cruce entre un hombre que es heterocigoto para el tipo de sangre B y una mujer que
mylen [45]

Answer:

F1) 1/4 = 25% de la porgenie será AB, IAIB

     1/4 = 25% de la progenie será heterocigota para el tipo A, IAi

     1/4 = 25% de la progenie será heterocigota para el gruo B, IBi

     1/4 = 25% de la progenie será homocigota recesiva, ii

Explanation:

  • El gen I determina el tipo de sangre de una persona. Es un gen dialelico que muestra alelo dominante I y recesivo I.
  • En personas de tipo A, los alelos son IA dominante, i recesivo.
  • En personas de tipo B, los alelos son IB dominante, i recesivo
  • IA e IB son codomiantes entre si, lo que signofica que hay un tercer fenotypo IAIB, expresando ambos tipos de sangre juntos.  
  • El alelo i es recesivo siempre.

Genotipo A:

  • IAIA, Homocigota dominante
  • IAi, Heterocigota
  • ii homocigota recesivo

Genotipo B:

  • IBIB, Homocigota dominante
  • IBi, Heterocigota
  • ii homocigota recesivo

Genotipo AB:

  • IAIB, Homocigota dominante

In this lab, you will explore the microscopic process of building proteins from RNA. Instead of working with variables, you will
Tamiku [17]
The investigative question that would focus on the steps of the process of exploring the microscopic building of proteins from RNA would start with a 'how'. This is because how questions ask about the process. For example, 'How are proteins built from RNA?' would be a good investigative question.

The genetic switch controlling whether a bacterium enters the lytic or lysogenic cycle relies on the binding of which two protei
givi [52]

Answer:

Cro and lambda

Explanation:

In the lysogenic cycle, the viral DNA is within the host DNA, while in the lytic cycle the viral DNA is separated from the bacterial cell, replicating independently from the bacterial DNA. The cro and lambda are DNA-binding repressor proteins of the bacteriophage lambda which bind to different operator sites, i.e., different genetic sequences found between the promoter and the structural gene. These proteins are known to have complementary functions in lytic and lysogenic cycles. The cro protein repressor binds non-co-operatively to operator DNA regions, while the lambda protein contains a domain (carboxy-terminal) that binds co-operatively to operator regions.
