PPT-Protein Synthesis Transcription

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA mRNA DNA unzips to open the codes that need to be make certain proteins. DNA .  RNA  Protein. 2 Major Steps. Transcription. – DNA is transcribed (copied!) into single stranded mRNA . (DNA code transcribed into RNA code). Translation. – mRNA is translated into protein (amino acids). C483 Spring 2013. 1. Which . of the following is true about . transcription regulation? . A) A repressor protein activates transcription of a negatively regulated gene. . B) A positively regulated gene can be transcribed only in the absence of active repressor. . Chapters 16 and 17.

Many questions pertaining to this genetic code were posed in the late 1950's:. • How many RNA nucleotide bases designate a specific amino acid?. If separate groups of nucleotides, called . Look deep into nature, and then you will understand everything better.. Albert Einstein. . one-gene, one-enzyme hypothesis. Many enzymes are composed of more than one polypeptide chain, or subunit (that is, they have a quaternary structure). In this case, each polypeptide chain is specified by its own separate gene. Thus, it is more correct to speak of a one-gene, one-polypeptide relationship: The function of a gene is to control the production of a single, specific polypeptide.. 69NB. Directions:.
