Answer:
This condition states that Xander's body temperature is normal. The human feels a little warm. It is due to the various metabolic activities that takes place inside human body.
Not everyone has the same body temperature. The normal body temperature is 38°C. But this can be a bit higher in case of children.
The temperature of the human does not stays same all day. It varies according to the work you do and the time of the day.
Explanation:
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:
Non-coding DNA regions play important roles in regulating transcriptional activity by encoding different types of non-coding RNAs (ncRNAs), acting as scaffold attachment regions, acting as enhancer specific regions, etc.
Explanation:
Historically, it had been believed that non-coding DNA sequences were 'junk DNA' since they don't encode for proteins (beyond the sequences that are transcribed into functional non-coding RNAs, i.e., transfer RNA and ribosomal RNA). However, in the last years, it has been shown that non-coding DNA sequences play critical roles in regulating gene expression and genome function. For example, evolutionary conserved non-coding RNAs (ncRNAs) with regulatory roles on gene expression such as, for example, long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) have been mapped in non-coding DNA sequences, thereby evidencing the functional significance of these regions. In consequence, the conservative nature of certain non-coding DNA sequences evidence that mutations in such regions may have significant deleterious effects, and thereby they could have a negative impact on the fitness of the individual.
Genetic Drift is a term used to describe part of the evolutionary process. Genetic Drift is a term describing the random environmental factors such as volcanic eruptions, trees falling down, forest fires etc, that affect the gene frequency in the population of a species after the event has taken place. So, we can say that genetic drift in a population can affect the gene pool by either allowing the gene pool to increase of decrease. A typical example is that of the worldwide rhino population. The more the rhinos are poached, the smaller the genetic pool becomes. Eventually this can lead to the extinction of the species.
