Whether a fly has white or red eyes is due to alleles at a single locus. It is thus a _______ or _______ trait.
maxonik [38]

Answer:

The correct answer is "qualitative, discrete".

Explanation:

A qualitative or discrete trait is defined as a characteristic that have no intermediate features, and is often the result of genetic alleles at a single locus. For instance, if the form the seeds of pea could be either round or wrinkled, but not with intermediate forms. This is the case of the fly that has white or red eyes, but does not have pink eyes or other colors in between.

Gene expression might be altered at the level of post-transcriptional processing in eukaryotes rather than prokaryotes because o
Iteru [2.4K]

Answer:

<h2>As transcription and translation occurs in different location in eukaryotes, while in prokaryotes, both the processes occurs at same location,  post-transcriptional processing in eukaryotes. </h2>

Explanation:

The transcription and translation occurs in different location in eukaryotes, while in prokaryotes, both the processes occurs at same location and can be co-translation.

As, in eukaryotes, the transcription occurs in the nucleus and then this transcript have to move in the cytoplasm to translation, so before reaching in the cytoplasm, various modifications occur in this transcript known as post transcriptional modification or processing ( include 5' capping, 3' poly-adenylation and RNA splicing).

As, in prokaryotes, both transcription and translation occur at same place so there is no time for modification for transcript because translation starts as the transcription is still going on.

A molecule with the formula C18H36O2, would probably exhibit which of the following characteristics?
Mashcka [7]
The answer would be A—the molecular formula given is that of a long-chain, saturated fatty acid, which would be insoluble in water (i.e., hydrophobic).

—————————

B describes carbohydrates, which can function as a storage of energy (e.g., starch or glycogen) or structural components (e.g., cellulose). The three examples just given are polymers of glucose, a monosaccharide; monosaccharide generally have the empirical formula CH2O; this is not the empirical formula of the given molecule (and, in any case, there are too few oxygen atoms for the number of carbon atoms), and so B is incorrect.

C describes an amino acid, likely an α-amino acid, which consist of a central, saturated carbon bonded to amino (—NH2) and carboxyl (—C(=O)OH) functional groups and a variable side chain, which determines the amino acid’s properties. Since the formula of an amino acid must contain nitrogen, which the formula given doesn’t have, the molecule couldn’t be an amino acid, and so C is incorrect.

D describes nucleic acids. Examples include DNA and RNA; nucleic acids and the nucleotide monomers that comprise them contain a nitrogenous base and a phosphate group. The given molecule’s formula has neither nitrogen nor phosphorus, and so cannot represent an amino acid, making D incorrect.
