3. Describe the benefits and drawbacks of experiments in a laboratory compared to experiments done in a
labwork [276]

Answer:

Benefits:

In  a lab, scientists can control the conditions according to their research and study. This allows them to focus on a single perspective.

On the other hand, in a natural setting there are complex interactions due to which focusing on a single attribute can be difficult.

Drawbacks:

Ina  laboratory experiment, we cannot control every variable which might be having an effect on our concerned subject as compared to a natural setting. This is because lab experiments are performed in a controlled experiment. Hence, there might be difference of results in a lab experiment and nature.

In pea plants , yellow pod color is recessive and green pod color is dominant . A heterozygous dominant for that trait . What pe
almond37 [142]

The question is incomplete. The complete question is:

In pea plants, yellow pod color is recessive and green pod color is dominant. A heterozygous plant produced offspring with a plant that is homozygous dominant for the trait. What is a percent chance that the pea plant will have green pods.

Answer:

100%

Explanation:

Let's assume that the allele "G" gives green pod color while the allele "g" imparts yellow color to the pods. The genotype of the heterozygous plant would be "Gg". A cross between heterozygous green plant (Gg) with homozygous dominant (GG) plant would produce progeny in following ratio=

Gg x GG= 1/2 GG (green): 1/2 Gg (green)

Therefore, there are 100% chances that the progeny plant will have green pods.

Lubov Fominskaja [6]

Answer:

Mutations in introns create alternative splicing site which in turn make mRNA with reduced or no translation.

Explanation:

Introns regulate the splicing of heterogenous RNA during post transcriptional modifications as well as affect the stability of mature mRNA. The stable mRNA is more likely to be translated into proteins. So, introns also regulate the translation of mRNA.  

In human beta thalassemia, mutations in intron create alternative splicing sites which in turn affect the formation of beta globin chain of hemoglobin. Lack of beta globin chain reduces the amount of functional hemoglobin and causes anemia.
