Answer:
One of the RNA molecules has experienced gene duplication as the result of translocation.
Explanation:
Translocation and duplication are some of the structural abnormalities in the chromosomes that may even cause certain genetic disorders. Duplication is the presence of a genetic segment for more than one time in the chromosome. The repeated genetic segments are mostly present in the tandem pattern. When a chromosome fragment breaks off and attaches to a non-homologous chromosome, it is called translocation. It leads to the deletion of a genetic segment in one chromosome and duplication in the other.
According to the given information, a genetic segment bearing two genes is detached from one RNA and gets attached to the other RNA molecule of the HIV genome. Therefore, the RNA molecule has undergone translocation and has lost a genetic segment while the other has gained a genetic segment (duplication) due to translocation.
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:
A.
Explanation:
A parasite does not feed it's host; in fact, it takes food energy/ food from it's host.
