Card preview (6)
____ The use of a gene to make a protein Includes the synthesis of the protein by the processes of transcription of DNA and translation of mRNA May also include further processing of the protein after synthesis
Gene expression
Is transcription and translation simultaneous in eukaryotes?
No, only in prokaryotes cause everything occurs in the cytoplasm
In eukaryotic cells, gene expression is regulated at the epigenetic, transcriptional, post-transcriptional, translational, and post-translational levels In what levels does this happen in prokaryotes?
Transcriptional level Epigenetic Post-translational
____ The mechanisms and systems that CONTROL the expression of genes ____ Overall process by which information encoded in a gene is converted into an observable phenotype
Gene regulation Gene expression
Why regulate gene expression? (3)
Adjust to sudden changes Conserve energy Save resources
In ____ (all of the mechanisms involved in regulating gene expression) the most common is the regulation of ____ Although mechanisms influencing the processing, stabilization, and translation of mRNAs help control the expression of some genes.
