Options are not given in the question. The complete question is as following:
Gene expression is often assayed by measuring the level of mRNA produced from a gene. If one is interested in knowing the amount of a final active gene product, a potential problem of this method is that it ignores the possibility of _____.
A) chromatin condensation control
B) transcriptional control
C) alternative splicing
D) translational control
Answer:
D) translational control
Explanation:
Gene expression is the mechanism used in the production of a functional gene product through information from a gene. This results in much more rapid cellular change by direct protein concentration regulation.
Translational regulation refers to regulating the protein concentrations synthesised from its mRNA. This control is of great importance for the cellular response to stressors, signs of growth and differentiation. This results in much more rapid cellular change by direct protein concentration regulation.
Hence, to evaluate gene expression it is important to measure the possibility of translational regulation as most of the time, function of the stop codon is ignored by ribososme which leads to long peptide chains and interfer with gene expression.
So, the correct answer is D).
Answer:
Exponential population growth: When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce.
Explanation:
B. to make cellulose in the cell walls
Answer:
The longer-spined sea urchins existed before the shorter-spined sea urchins
Explanation:
The lower buried is what died off first and the recently buried is the newly evolved version.
