For example AUG is start but UAG is start that is a frameshift mutation that has different bases but same amino acid
The answer is B . just think like foot ball players or other characteristics.
Answer:
A general decrease in transcriptional activation
Explanation:
When acetyl groups are added to histone proteins by acetyltransferase enzymes, the 30-nm chromatin fiber will not be formed because the proteins are prevented from doing so. This further destabilizes the chromatin structure and allows the occurrence of transcription. However, raising the cells to 40°C does not allow the acetyltransferase enzyme to function and hence the acetyl group will be hindered from being added to the histone protein which is the main target of the enzymes. Thus, transcription activation will be blocked because the chromatin and nucleosomes would remain stabilized.
Answer:
An increase in the number of H+ ion in the lake with many aquatic would cause cell shrinkage by the removal of water from the cell.
Explanation:
Every organism tries to maintain a constant PH inside their body to regulate the homeostasis of their body.
An increase in the number of H+ ion or proton in a lake will increase the osmotic pressure of the water present in the lake.As the osmotic pressure of Lake"s water is increased it will draw water out from the the cells of aquatic organism causing the cells to shrink thus decreasing the volume of the cell and if the H+ ion concentration rises at a high level cell death can occur.
