Answer:
Double stranded RNA may affect gene expression negatively
Explanation:
Double stranded RNA are molecules that can affect negatively the gene expression by the fact that this kind of molecule can be complementary to others RNA molecules, or also to DNA regions on the genome. Therefore, introducing such molecules in mammalian cells can inactivate the transcription of a specific gene by the fact that those molecules could block regions of the genome that code for a gene or by connecting to some RNA molecules by similarity. Such mechanisms will reduce the production (or expression) of a given protein in these cells.
Explanation:
Introduction. The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose.
I THINK THIS IS THE ANSWER GOOD LUCK
Chickens have 78 chromosomes.
Based on these facts, we can state that the genes of the two organisms had a eukaryotic origin.
We can arrive at this answer because:
- Despite having exons, prokaryotes do not have introns in their genomes.
- This means that if two organisms have the same sequence of introns and exons, they have a common ancestor, in addition to having their genes originated in a eukaryotic organism, which explains the sequence of introns.
This means that the genetic expression of these two organisms has similarities, even if they are organisms with different biological processes.
