Answer:
Transcriptional regulators function to regulate the expression of different genes and also to affect the expression of other transcriptional regulators, thereby the combination of a few transcriptional regulators is sufficient to modulate gene expression patterns
Explanation:
Transcriptional regulators are able to control gene expression by binding to cis-regulatory elements on the genome. For example, in plants, MADS-box proteins are transcriptional regulators that contain an evolutionary conserved DNA-binding domain (i.e., MADS-box domain) which regulate simultaneously the expression of many different genes by binding to a conserved DNA motif called CArG box [CC(A/T)6GG] located in the promoter region of many genes expressed at specific stages of plant development. Within the cell, transcription regulators function not only by controlling the expression of different genes but also by affecting each other's activity, thereby creating different combinations where the expression of a limited number of transcription regulators is sufficient enough to regulate gene expression patterns.
Answer: 4
Explanation: The smallest fragments travel the furthest distance through the gel plate because are able to move quickly through the gel.
Answer:
C
Explanation:
During their development, many organisms look similar, suggesting that very different organisms may have a common ancestor. - Think of the human fetal neural / spine development which mirrors other species.
