Answer:
a. repressor
b. regulator
c. operator
Explanation:
All constituent genes of an operon are transcribed in a coordinated manner, such as polycistronic mRNA, that is, multigenic, which is sequentially translated into proteins by ribosomes. The initiation of transcription can be regulated positively or negatively. The genes under negative control are constantly expressed unless they are "disconnected" by a repressor protein that will prevent gene expression by binding to a specific DNA sequence called operator, preventing RNA polymerase from initiating transcription in the promoter.
Those genes whose expression is under positive control will not be transcribed unless an activating protein is present which binds to a specific DNA sequence and helps RNA polymerase in the initial steps of transcription.
Answer:
25%
Explanation:
In sheep, the allele for belly fur (A) is dominant to the allele for no belly fur (a). A mother with the genotype Aa and a father with the genotype Aa produce an offspring. What is the percent chance that the offspring will have NO belly fur?
Allele A is dominant over allele a.
Genotype of mother = Aa
Genotype of father = Aa
Crossing Aa and Aa:
Aa x Aa = AA, 2Aa, and aa
Since A is dominant over a, both AA and Aa have belly fur.
Hence, the ratio of the offspring with belly fur to those without belly fur is 3:1.
Percentage of the offspring without belly fur is 25%.
<h3>Hi!</h3>
The correct answer is D. Decrease in soil fertility.
<h3>Explanation:</h3>
A particular crop has a particular need for certain nutrients, and contributes a certain set of nutrients in return to the soil. When the same crop is planted over and over the years, the certain set of nutrients required to sustain are used up, and an accumulation of particular nutrients not essential for that particular plant's growth piles up. This leads to poor growth and development of the plant due to nutrient deficiency - and the quality of a soil to sustain growth and agriculture of a plant is known as fertility, which in this case decreases.
