Answer:
a, b, c are correct
Explanation:
Enhancers are DNA sequences that increase the rate of transcription. Enhancers act as binding sites for transcription factors that stimulate the transcription of one or more genes and enhancers stimulate transcription for specific cell type or tissue in a specific manner. The possible reasons for the lack of enhancers in bacteria include.
Enhancers often provide a mechanism for cell-specific transcription of genes, and most bacteria lack differentiated cell types.
Bacterial operons make coordinate regulation of protein synthesis by enhancers unnecessary.
There is little to no intergenic space on bacterial chromosomes, which makes long-range-acting enhancer sequences unnecessary.
Therefore, the correct options are (a), (b), and (c).
I believe the ratio of C to H to O in simple sugars or monosaccharides are 1 C : 2 H : 1 O or 1:2:1.
Answer:
cause tumors to develop.
Explanation:
Oncogenic viruses are viruses that do not kill or lyses the cells of the host outright but has the capacity to cause to cause a long term infections that may eventually lead to the formation of tumor or cancerous cells within the body of their hosts.
<em>Hence, the fourth option is the correct option. That is, they cause tumors to develop</em>
