Answer:
A-B-C-D
Explanation:
PROPHASE; 1. chromosomes become thicker
2. nuclear membrane disintegrates
3. centrosome divide to form centrioles
4. centrioles move to the opposite polls of the cell
METAPHASE; 1. chromosomes get arranged at the equator
2. centrioles produce spindle fibre that attach to the middle of the chromosomes
ANAPHASE; 1. shortest stage of mitosis
2. spindles will pull apart each chromosomes to form chromatids
TELLOPHASE; 1. each chromatid moves to opposite polls of the cell
2. nuclear membrane appears around both of them
3. the centrioles sill stop producing spindles
4. centrosomes will then form again
cytokinesis then divides by the cleavage furrow to form the two daughter cells
As the wolf population increases, the need for food will increase, causing the wolves to hunt more hares, making the hare population decrease.
Stage 3 because the person fev1 level is go down not up
The main difference is that mitosis occurs in body cells and meiosis occurs in sex cells. Mitosis produces identical daughter cells and meiosis produces genetically different daughter cells.
Answer: The correct answer is B) Frameshift mutation.
The given mRNA sequence is GGU-GCU-CCU-AUU. When a nucleotide is added at the fourth location in the chain, it entirely changes the frame from the insertion of the nucleotide till the end of the gene sequence. This is called a frameshift mutation.
This is because after adding a nucleotide, a new frame is generated that will code for different amino acids and therefore a different protein will be synthesized.
On the contrary, chromosomal mutation is an abnormality in the chromosome ( in terms of number or structure) whereas substitution mutation is the one, which exchanges one base with another. Deletion of base also results in the frame-shift mutation.
