With this information I don’t fully understand the question but broadly speaking any sequence that would not made transcribed into the correct RNA from the DNA will be
mutant.
Example is the first normal DNA is read 5’ - GGT 3’ and the RNA will be 3’CCA’ 5’ as it is COMPLEMENTARY. (Important keyword with this)
If the assignment wants you to have a silent mutation that Change the RNA to something that is not complementary to the DNA but will still produce that same protein as the example above. If you need to make a new protein change the rna so the codon will make a different protein from the above sequence
I believe the answer to your question is the cortex
I think the answer is vibrssae or whiskers.
Cytokinesis is the process wherein actual division of the cell, including the cell membrane and the cytoplasm, from the parent cell to two daughter cells. The correct answer in this question is "the metaphase plate is the beginning area for cytokinesis" as the metaphase plate dictates the midpoint of the cell. A cell with a cell wall (plant cell, for example) cannot perform cytokinesis with a cleavage furrow but with a cell plate. Phragmoplast only develops in plant cells. Lastly, cytokinesis only starts after telophase.
Chloroplasts and mitochondria are organelles found in plant cells. Chloroplasts contains the cholrophylls while the mitochondria is the powerhouse of the cell where energy is found. In this case, the two organelles not only have inner membranes but also their own DNA and ribosomes
