Answer:
a. to treat a disease characterized by a gene that is not expressed.
Explanation:
The RNA interference (RNAi) technique is widely used in molecular biology to inhibit target gene expression at the post-transcriptional level. The RNAi technology uses small interfering RNAs (siRNAs) consisting of 18-22 nucleotides that bind to complementary acid nucleics (i.e., DNA and RNA), thereby inhibiting target gene expression. Recently, it has interestingly been discovered that small RNA sequences targeting promoter regions can also be used to activate the expression of endogenous target genes through a mechanism called RNA activation (RNAa).
Answer:
Smooth and green seeds
Smooth and yellow seeds
Wrinkled and green seeds
Wrinkled and yellow seeds
Explanation:
This is a typical dihybrid cross involving two linked genes; one gene coding for seed texture and the other for seed colour. The allele for Smooth seed (S) is dominant over the allele for Wrinkled seed (s) in the first gene while the allele for green seed (G) is dominant over the allele for yellow seed (g) in the second gene.
The cross is between a heterozygous smooth, green plant and a homozygous recessive wrinkled, yellow plant
According to the law of independent assortment, each parent will undergo meiosis to produce the following gamtes with genotypes:
SsGg: SG, Sg, sG, sg
ssgg: sg, sg, sg, sg
Using a punnet square to perform a cross between these gametes ( check attached image), a total of 16 offsprings with four different phenotypes will be expected. The phenotypes are as follows:
SsGg: Smooth and green offsprings (4)
Ssgg: Smooth and yellow offsprings (4)
ssGg: Wrinkled and green offsprings (4)
ssgg: wrinkled and yellow offsprings (4)
