Answer:
b. Marked differences in male and female anatomy and temperament.
Explanation:
Sexual dimorphism describes the condition where the two sexes of the same species shows difference in characteristics besides the differences in colour, shape, size, structure and their sexual organs. Exhibition of different morphology and anatomy in two sexes of the same species are the result of transmission of one or the other sexual pattern present in the genetic material.
In some species, one sex or the other often shows traits that are not found in the other which appear not adequate to the environment .
Grouping of 3 based in MRNA are codons
Answer:
d. Genes that play a role in the same metabolic pathway are organized into an operon.
Explanation:
In prokaryotic organisms like bacteria, polycistronic mRNAs exist which means that each gene does not have a separate promoter of its own. In fact many genes are under the control of a single promoter. These genes being a part of same metabolic pathway are organized into an operon. For example, lac operon and tryptophan operon. In lac operon, three genes named as β-galactosidase, permease and transacetylase are expressed under a single promoter which is known as lac promoter.
In contrast to this, in eukaryotes the mRNAs are monocistronic i.e. only a single gene is controlled under a single promoter.
