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:
Meiosis is a special type of cell division in sexually-reproducing organisms used to produce the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome.
Explanation:
Explanation:
Prokaryotes are able to undergo mitosis for cell division, which is faster than meiosis in eukaryotes. This ensures the survival of their species.
Answer:
1:1 (brown:blonde)
Explanation:
Brown hair color (B) is dominant over blonde hair color (b).
Heterozygous parent will have the genotype Bb
Homozygous recessive parent will have the genotype bb.
Crossing hetezygous parent with homozygous recessive parent:
Bb x bb
Progeny: Bb, Bb, bb, and bb.
2 Bb brown hair
2 bb blonde hair
Phenotypic ratio = 1:1 (brown:blonde)
The correct answer is 1:1 (brown:blonde).
Answer:
Find the area of a square or rectangle by multiplying the length times the width. This formula looks like l*w. If the length is 5 and the width is 2, the area is 10 square units.
