A classic example of selection in natural populations involves the peppered moth Biston betularia in England. Industrial gases k

illed the lichens and mosses on buildings, trees, etc., and soot deposited on the landscape. Dark-colored moths gained a selective advantage. In this case, one would say that there was selection against the light-colored moths. Which morph, light or dark, would have the highest fitness? (Enter light or dark in the box below.)

Answer:

Dark colored moth

Explanation:

Moths either dark or light live on the bark of the trees. During industrial revolution in England, excessive pollution caused the darkening of bark of trees. Due to this environmental change, some of the light colored moths evolved and turned into dark colored moths. Both bark and moth being dark in color, made the moths untraceable by their predators. While the light colored moths on dark trees were easily recognizable by their predators.

Hence, the dark colored moths possess high fitness.

Create an explicit equation for each recursively-defined sequence below.
lbvjy [14]

Answer:

  t(n) = 3·5^(n-1)

Explanation:

The recursive formula describes a sequence in which each term is 5 times the one before it. This is a geometric sequence with common ratio 5 and a first term that is said to be 3.

As you know, the generic formula for a geometric sequence is ...

  an = a1·r^(n-1)

For a1 = 3, r = 5, and a sequence named "t", this is ...

  t(n) = 3·5^(n-1)

In which ways can the individual steps of this process be regulated to lead to higher or lower expression of a particular protei
Dahasolnce [82]

Answer:

There are many points at which eukaryotic gene expression can be controlled, through pretranscriptional control, transcriptional control, and posttranscriptional control

Explanation:

The pretranscriptional control determines the accessibility of chromatin to the transcription machinery. It is affected by supercoiling and methylation. It is also known as epigenetic regulation, and it does not depend on the sequence but on the conformation of the DNA.

While transcriptional control determines the frequency and / or speed of transcription initiation through the accessibility of the start sites, the availability of transcription factors and the effectiveness of promoters.

The post-transcriptional control is the one that is exercised once the transcript has finished synthesizing. It can be of several types:

• Maturation control: As the RNA adjustment can be made.

• Transport control: Most RNA has to go out to the cytoplasm to perform its function. For this they have to cross the pores of the nuclear membrane, where you can select the RNAs that will be transported and those that will not.

• Stability control: The half-life of RNA can be regulated by the expression of RNAs or mRNA stabilizing proteins in the cytoplasm.

• Translational control: It is exercised on the frequency with which the mRNAs begin to be translated. It can also affect the frequency with which proteins mature and the availability of enzymatic effectors.
