Question

This biological level of organization is represented by all three steps of the gene expression products. ____________

Answer 1

Answer:

The biological level of organization represented by all of the three steps of gene expression products is the central dogma of molecular biology.

Explanation:

DNA is divided up into functional units called genes. Each of them provides instructions for a functional product, that is, a molecule nedeed to perform a job in the cell. In many cases, the functional product of a gene is a protein.

The functional products of most known genes are polypeptides.  Genes that specify polypeptides are called protein-coding genes.

Not all genes specify polypeptides. Instead, some provide instructions to build functional RNA molecules, such as transfer RNAs and ribosomal RNAs that play roles in translation.

The construction of polypeptide involves two major steps: transcription and translation. During the transcription, the DNA sequence of gene is copied to make an RNA molecule and in translation the sequence of mRNA is decoded to specify the amino acid sequence of the polypeptide.
