The _Embryo_ is the answer
Hope this helps
The thing that is happening when you gargle with salt water is you are creating a high-salt barrier. As a result fluids are pulled out from the tissues in the throat area and the viruses are washed out. Fluids (water) are moving down the concentration gradient (to the area with the high salt concentration) and this is an example of passive transport.
This is a very good question and the answer to it is option A. The common core set of genes is very similar between all organisms.
This is true because several facts, for example, all living beings on earth share the same gene code: DNA, all of them are based on DNA or RNA, which humans have it too. This was explained by Darwin's evolution theory, we are all descendants of just one single species, and because of that, all species have something in common between them.
That's why there's a possibility that a human gene can correct a defective gene in a yeast cell. Although this could really happen, we are not sure about it, it's a possibility, don't always be sure of something in biology, there's always more to understand and to learn.
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).
