A person should know the effect of auxins as it helps in growth of the stems and the person should know how much he should cut otherwise will keep cutting it non uniformly affecting the plant growth and exposure to sunlight.
Answer:
The correct answer is: a.
Explanation:
- A Diploid organism possess two copies ( also called alleles) of each autosomal gene, of which one copy of the gene is obtained from one of its parents and the other copy from its other parent.
- During the process of replication, one of the alleles of the GTPase encoding gene undergoes a mis-sense mutation.
- A Mis-sense mutation can be defined as a non-synonymous mutation in which one of the nucleotide in the sequence of the gene gets altered such that it causes a change in the amino acid encoded by the codon (triplet nucleotide message encoding for a single amino acid) formed by the mutated nucleotide. A single amino acid change in the protein, if occurs in the functional site of the protein, can render a protein non-functional.
- Hence, the mis-sense mutation in one of the alleles encoding for the GTPase gene causes the resulting protein produced from the mutated allele to have drastically reduced function (1%).
- A heterozygous cell is one which has one copy of the normal allele and the other copy of the mutated allele of the GTPase encoding gene.
- As one copy of the normal GTPase allele is present in such an individual, it can produce the normal GTPase protein that can assist in the process of cell growth and division.
- Hence, the phenotype(expressed character) of the heterozygous cell will not be affected due to the mutation and it will be able to grow and divide normally.
Answer:
The correct answer will be- the color change will be observed and the solution will turn purplish-black.
Explanation:
Iodine test is performed to test the presence of the carbohydrates mainly starch.
The iodine solution is chemically called potassium iodide which forms a yellow solution. The potassium iodide solution forms a complex with a starch solution which appears a purplish-black color which shows the presence of the carbohydrates.
In the given question, if we add the iodine solution to the beaker after a certain point of time then it will still form a complex with the starch and thus beaker solution will appear darker in color.
