Answer:
E. All of these mechanisms are used; there is no single universal mechanism.
Explanation:
Gene expression is regulated at many levels. Some of them are:
- Chromatin remodeling regulation includes altered histone modifications such as methylation which can regulate gene expression (up or down).
- Transcription is regulated via transcriptional factors and specificity factors such as repressors and activators.
- RNA processing can be regulated through the alternative splicing (different introns can be excised and combinations of different exons connected)
- Post-translational modification refers to modification of proteins after being synthesized.
Polymerase chain reaction to amplify the DNA would be the technique used in the blood lab.
