What is the effect of ph and temperature on an enzyme

1 answer:

7 0

Enzymes are affected by the pH and temperature of their environment. For instance, stomach enzymes are meant to function in highly acidic environments. However, other enzymes have different functions, and may thrive in a lower pH. When an enzyme is exposed to a much higher or lower pH than they are made to function at, they become denatured. The same is with temperature. Exposing an enzyme to high temperature can denature it too. Hope this helps! :)

Answer:

It ensures that sexually reproduced offspring have the correct amount of chromosomes when born, this ensures that disorders such as down syndrome don't occur. It also makes genetic variation possible, by way of genetic recombination, this is so that siblings don't look exactly the same, disregarding twins.

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

Answer:

The three processes from left to right are:

Replication DNA Trancription RNA Translation Protein

Explanation:

The process in question in the diagram is called the central dogma of life which describes the flow of genetic information from DNA to RNA to Protein. The three processes involved are:

DNA Replication
Transcription
Translation

DNA Replication:

DNA replication is the process by which DNA makes a copy of itself. Replication of DNA is semi-conservative. this means that each new helix is a combination of an old (parent) strands and a new (daughter strand). The parental strand is used as a template to generate a complementary daughter strand.

Transcription:

Transcription is the formation of an RNA transcript of the DNA template. This process yields a mRNA that is further used as a code to manufacture proteins in the process of translation.

Translation:

Translation decodes the mRNA formed in transcription to generate proteins with specific amino acid sequence.
