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).
Answer:
We need the events to be able to put them in order. :\
Explanation:
Answer:
having a genetically diverse population make a species more likely to survive a change to the enviroment because random mutations can occur in a species and if a sudden change in the environment were to occur like extreme heat for example, some of the mutations in their DNA may help them survive this extreme heat and the species will be more likely to survive
Answer:
Nicholas Steno
Explanation:
Nicholas Steno who was a Catholic priest establish relationship between sedimentary rock layers otherwise called stratigraphy.
Stratigraphy is a branch of geology that deals with the study of rock layers. He established theoretical law of stratigraphy by introducing law of superimposition, principle of original horizontality and the principle of lateral continuity in 1669 work of fossilization of organic matter sediments.
