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).
-Presence of jointed appendages and gills, lungs, jaws.
-Presence of a chitinous external skeleton or exoskeleton that change periodically.
-Body constituted by repetitive segments, phenomenon known as metamerism<span>.</span>

The first thing is that the enzyme, DNA helicase
breaks the hydrogen bonds to unzip the double strand of dna for replication to take place
