Answer:
An antisense sequence with complementary to the target mRNA encoded by the gene of interest
Explanation:
An antisense sequence is usually a short RNA sequence specifically designed in the laboratory to bind by complementary to the DNA/RNA sequence of interest (usually a target mRNA) whose expression is desired to be inhibited. When an antisense bind to its target mRNA, the antisense sequence acts to block translation, thereby inhibiting protein synthesis. Moreover, it has been shown that the double-stranded antisense-RNA complexes may also increase the susceptibility of the target sequence to RNase H digestion.
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).
A benefit of the carbon cycle is that it is critical to the food chain. The carbon cycle is important to all ecosystems as well as the food chain.
Carbon is an important element in living tissues and in all organic matter. All living things are made of carbon.
Plants use carbon from carbon dioxide gas in the atmosphere to make their own food and to grow. The carbon becomes part of the plant. Plants are consumed by animals. Thus the carbon cycle plays a vital role in the food chain.
