The incidence of cystic fibrosis, a recessive genetic disorder in the Caucasian population of United States, is

Biology
1 answer:
kaheart [24]2 years ago
4 0
Cystic fibrosis occurs 1 in every 2,500 individuals.
Using Hardy Weinberg principle,
freq. of recessive allele/ q2 = 1/2500 = 0.0004
Take the square root,
q = 0.02
freq. of dominant allele/ p = q - 1
p = 0.98
freq. of heterozygous individuals = 2pq = 0.04

Therefore, the answer is 0.04, which is C.

Compare and contrast Prophase and Telophase. what is different about DNA of the chromosomes in these phases. ( Max 5 Sentences )
shepuryov [24]

Answer:

The C. elegans embryo is a powerful model system for studying the mechanics of metazoan cell division. Its primary advantage is that the architecture of the syncytial gonad makes it possible to use RNAi to generate oocytes whose cytoplasm is reproducibly (typically >95%) depleted of targeted essential gene products via a process that does not depend exclusively on intrinsic protein turnover. The depleted oocytes can then be analyzed as they attempt their first mitotic division following fertilization. Here we outline the characteristics that contribute to the usefulness of the C. elegans embryo for cell division studies. We provide a timeline for the first embryonic mitosis and highlight some of its key features. We also summarize some of the recent discoveries made using this system, particularly in the areas of nuclear envelope assembly/ dissassembly, centrosome dynamics, formation of the mitotic spindle, kinetochore assembly, chromosome segregation, and cytokinesis.

1. The C. elegans embryo as a system to study cell division

The C. elegans embryo is a powerful model system for studying the mechanics of metazoan cell division. Its primary advantage is that the syncytial gonad makes it possible to use RNA interference (RNAi) to generate oocytes whose cytoplasm is reproducibly (>95%) depleted of targeted essential gene products. Introduction of dsRNA rapidly catalyzes the destruction of the corresponding mRNA in many different systems. However, depletion of pre-existing protein is generally a slow process that depends on the half-life of the targeted protein. In contrast, in the C. elegans gonad, the protein present when the dsRNA is introduced is depleted by the continual packaging of maternal cytoplasm into oocytes (Figure 1). Since depletion relies on the rate of embryo production instead of protein half-life, the kinetics tend to be similar for different targets. By 36-48 hours after introduction of the dsRNA, newly formed oocytes are typically >95% depleted of the target protein.

What should be your response as you approach a roundabout?
BigorU [14]
<span>The correct answer is B) choose the correct lane. It is always important when driving to ensure you are in the correct lane, but in roundabouts, it is essential to the traffic flow. Choice A is not correct because roundabouts are designed to slow down traffic and you need to be paying attention to what is going on and slowing down before you enter. Choice C is not correct because you do not have the right-of-way; the traffic already in the roundabout does and you would need to yield to them. Choice D is not correct because choices A and C are not correct.</span>
