Question

Which flowchart correctly shows how genes are inherited?

A.
RNA→ trait→ DNA→ protein

B.
trait→DNA→ protein→ RNA

C.
RNA→ protein→ DNA→ trait

D.
DNA→ RNA→ protein→ trait

Answer 1

It would go DNA, RNA, Protiens, Genes(traits)

This flow of information is dependent on the genetic code, which defines the relation between the sequence of bases in DNA (or its mRNA transcript) and the sequence of amino acids in a protein. The code is nearly the same in all organisms: a sequence of three bases, called a codon, specifies an amino acid. Codons in mRNA are read sequentially by tRNA molecules, which serve as adaptors in protein synthesis. Protein synthesis takes place on ribosomes, which are complex assemblies of rRNAs and more than 50 kinds of proteins.

The last theme to be considered is the interrupted character of most eukaryotic genes, which are mosaics of nucleic acid sequences called introns and exons. Both are transcribed, but introns are cut out of newly synthesized RNA molecules, leaving mature RNA molecules with continuous exons. The existence of introns and exons has crucial implications for the evolution of proteins.
