The eyes detect changes in posture and inform the brain about the position of the body, so vision is very important for maintaining balance, in the optic disc nerve fibers leave the eye.
Answer:
A) nutrient A only
Explanation:
In this case, enzyme A is required for the digestion of nutrient A, thereby evidencing that the mutation affects the enzymatic pathway and the mutant strain only can grow by supplementation with this nutrient. In molecular biology, mutant strains are useful to study enzymatic functions (for instance, the role of enzyme A in nutrient assimilation), as well as to examine downstream signaling pathways.
In experimental design, spontaneous mutations are induced to study their effects on the phenotype. Subsequently, reverse mutations may also be induced to reverse the forward mutation, thus restoring the original wild-type phenotype.
Mediterranean is the answer
Answer:Try asking on Yahoo they usually have the answers more quicker that we do.
Answer:
<h2>The cell will not pass the M checkpoint because its chromosomes will not associate with spindle fibers. or if the cell goes complete division, then the homologous chromosomes will go into either daughter cell.</h2>
Explanation:
As in the cell cycle, there are various checkpoints, which checks the cell in many steps like G1/S checkpoint, G2, M etc. They check the integrity of the genome, if there is any defect in the DNA/chromosome, it arrest the cell cycle.
Centromere is the region on the chromosome which binds with spindle fibers and is used in the separation of chromosomes during anaphase of cell cycle. If there is deletion of centromere, then the separation of chrmosome will be affected. Then the homologous chromosome can either go into one of the daughter cell, so one cell will get 2n+1 and other will get 2n-1.
