in a first attempt to describe the relationship between genes and phenotypes, beadle and tatum in the 1940s stated that each gene is a section of the genome that codes for a specific enzyme (one-gene-one-enzyme hypothesis). which more recent discoveries regarding gene expression are not covered by this hypothesis?

Respuesta :

  • Not all genes are translated into proteins; instead, some genes produce functional RNA molecules.
  • Proteins besides enzymes are coded for by genes.
  • More than one gene codes for multimeric proteins like RNA polymerase.

RNA- All living cells contain ribonucleic acid (abbreviated RNA), a nucleic acid with properties comparable to those of DNA. However, RNA is often single-stranded, unlike DNA. Instead of the deoxyribose present in DNA, the backbone of an RNA molecule is made up of consecutive phosphate groups as well as the sugar ribose.

Enzyme- A biological catalyst called an enzyme is usually always a protein. It accelerates a certain chemical process in the cell. The enzyme is continuously employed during the process and is not destroyed.
