Answer:
No, CREs usually don't account for differences in gene expression levels.
Explanation:
<em>Cis</em>-regulatory elements (CREs) are non-coding DNA regions that regulate adjacent gene <em>transcription</em>. They usually do it by binding to transcription factors. They are in charge of influencing the rate of which transcription occurs, and less with how much a gene is expressed. On the other hand, trans-regulatory elements are DNA sequences that encode for upstream regulators that can modify or regulate <em>gene expression levels</em>.
Therefore, cis elements are not really in charge of expression levels, mostly transcription rates of single genes, rather. Trans elements are more involved in expression levels.
D because they are complete systems

the process of polymerization, a chain of similar smaller molecules
called monomer join together to create very large molecules called
polymer. Through this chemical reaction, water is created as a
by-product. In contrast to hydrolysis or breaking down of polymers, a
water molecule is used to break the covalent bond that hold the
components of a polymer.</span>
The probability of a pea plant with genotype rryy producing a gamete with genotype ry is 1.
<h3>What would be the probability of a pea plant producing genotype ry from the genotype rryy?</h3>
- Probability is a measurement used in genetics to forecast the likelihood that a desired trait will be acquired by a child. The most easiest way to calculate the probabilities is to make a punnet square.
- The genotypes of a specific cross or breeding experiment are predicted using the Punnett square, a square diagram. It bears Reginald C. Punnett's name, who developed the method in 1905. Biologists use the figure to calculate the likelihood that a child will have a specific genotype.
- If we employ a punnet square for the genotype rryy producing a gamete with genotype ry the probability would be 1. You can refer the diagram for the understanding of the punnet square.
- F1 genotype: rryy
- F2 genotype: ry ry ry ry
- Thus the probability would be 1.
