Answer:
There are three types of DNA Mutations: base substitutions, deletions and insertions.
Base Substitutions. Single base substitutions are called point mutations, recall the point mutation Glu -----> Val which causes sickle-cell disease.
Deletions. ...
Insertions.
You first put the options for me to answer :)
<span>Interphase is the phase in the cell cycle during which cells that will undergo mitosis prepare for division. In interphase, DNA of the cell copies</span>. After that cell undergoes mitosis, which is the phase of the cell cycle during which cell divides on two identical. Mitosis consists of four phases:
1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up
2. Metaphase: Chromosomes line up at the centre of the cell.
3. Anaphase: The sister chromatids separate from each other to the opposite sides of the cells.
4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.
1.) For all of the above
2.) supplementary single-stranded ends.
3.) The strong negative charges from the phosphate groups in the DNA backbone cause it to migrate toward the positive pole.
The correct answer is: B. The water before filtration is a mixture because the particles could be physically separated.
A mixture is composed of more than one individual substances that can be separated using different methods (depending on the type of mixture). Methods for the separation include filtration, evaporation, distillation and chromatography. The dirt stays behind in the filter paper (it becomes the residue) andthe water passes through the filter paper (it becomes the filtrate).
