Which of the following statements describes the central dogma of molecular biology? A. Biological information in a cell passes from DNA to RNA to proteins.
B. Biological information in a cell passes from RNA to proteins to DNA.
C. Biological information in a cell passes from RNA to DNA to proteins.
D. Biological information in a cell passes from proteins to RNA to DNA.

The correct answer is A.  Biological information in a cell passes from DNA to RNA to proteins.

Explanation:

In a cell, the DNA carries the information contained in genes.  Through the process of transcription, the DNA is made into mRNA, and through the process of translation, the mRNA creates an amino acid strand, making a protein.  Therefore, the flow of information goes DNA to RNA to proteins.

Hope this helps!

structure is maintained and sustained by:

-cytoskeleton: gives cells coherence

-cell wall: support

-cytoplasm: shape

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
