Answer:
24 (n+1)
Explanation:
Trisomy refers to the presence of one extra chromosome in the genome of the organism. This means that the affected individuals have a total of 47 chromosomes, instead of 46.
Nondisjunction during meiosis I or meiosis II produce the gametes with one extra chromosome. For example, nondisjunction in egg mother cell results in the production of some egg cells with "n+1; 24 chromosomes".
Fertilization of the egg cell carrying 24 chromosomes with a sperm carrying 23 chromosomes forms a trisomic zygote with 47 chromosomes.
Atoms of some elements pull more strongly on shared electrons than do atoms of other elements, as a result, the electrons are pulled more toward one atom, causing the bonded atoms to have a slight electrical charge.
Mitochondria because it is the power house of the cell because it is responsible for ATP (
Answer:
The mutated protein would be the target for the new drug therapy.
Explanation:
Cancer occur due to mutation in some important genes that regulate cell cycle as well as cell division.The mutation of tumor suppressor gene such as retinoblastoma,p53,PTEN etc also leads to the onset of cancer.
Now the most important point to note that mutation in the these particular genes result in the formation of abnormal proteins or disease causing proteins.These mutated proteins are the principle cause for the occurrence of cancer.
As a result the mutated protein would be appropriate target for the new drug therapy .The drug will interact with the mutated protein and blocks the toxic activity of the later.
Answer:
Option C
Explanation:
The answer to this question is option C or "the leaves." The major site of photosynthesis in a plant is where the chloroplasts are located because it contains chlorophyll which is where photosynthesis takes place, chloroplasts is in all the green parts of a plant stem, leaves, and even the branches but it takes place mainly in the leaves of a plant because there is more leaves then roots or branches.
Hope this helps.
