Answer:
Please find the explanation below.
Explanation:
Changes in the genetic sequence of a DNA is called MUTATION. A gene is a segment of the DNA that holds information for the synthesis of proteins, which are responsible for the observable traits in organisms. The expression of a gene brings about the synthesis of a protein that effects a particular trait in an organism. The gene is expressed in two major stages viz: transcription and translation.
Transcription involves production of an mRNA molecule using the encoded information in the genes of a DNA while translation is the synthesis of a protein using the mRNA as a template.
Since, the order of the sequence in a gene determines the order of the sequence in the mRNA which ultimately determines the order of sequence in the protein, a change in the gene of an organism will affect the observed trait of that organism.
More detailedly, a change in the gene will cause a change in the mRNA sequence during transcription. A change in the mRNA sequence will cause a change in the amino acid sequence during translation. A change in the amino acid sequence will affect the protein produced i.e. might not be functional or may not be produced at all. An affected protein will cause a trait in that organism to be affected.
Answer:
tt
Explanation:
Firstly, look at the oldest female shape. It would be a circle since that is female and which circle, would be the oldest one. In line one. Since the circle is white, the gene has not been carried so it must be reccessive.
tt because it is the only allele pair that would give you the gene without obtaining that trait, meaning it is reccessive.
So it would make sense that tt is the choice.
If Morgan crossed XrXr and XrY, a white-eyed female and a white flied male, it will produce 2 XrXr(white-eyed female fly) and 2 XrY(white-eyed male fly).
Environmental Protection Agency (EPA) uses clean up authorities independently to address clean up situation:
-Under Superfund, or CERCLA, they find companies or the people responsible for contamination and negotiates with them to clean up the site.
-<span>Resource Conservation and Recovery Act (RCRA) provides EPA with enforcements authorities to ensure the sites are clean up.</span>
