Answer:
C) Promoter
Explanation:
Gene expression is the process of synthesizing RNA from a gene (transcription), and subsequently, proteins from mRNA (translation). In both prokaryotic and eukaryotic cells, gene expression is controlled at the transcriptional level, which is regulated by certain proteins called transcription factors. Transcription factors are proteins that regulate the synthesis of a protein from a gene.
Transcription factors regulate the progression of transcriptional process by binding to a regulatory region on the DNA sequence about to be transcribed called PROMOTER. The promoter region is a DNA sequence contained in the OPERON. This binding influences the binding of the transcription enzyme, RNA polymerase in order for transcription to start.
Answer:
Adaptive Radiation
Explanation:
Adaptive radiation refers to an evolutionary process in which organisms diversify from one ancestral species, which leads to different other forms and species. This tends to happen when organisms are pressured to adapt to a new environment.
Australian terrestrial mammals such as kangaroos, koalas, and wombats, are examples of this process. According to research, these iconic marsupials went through adaptive radiation in response to the expansion of grassland that occurred in the mid-Pliocene. Another example (the most famous one) is the case of Darwin's finches, which all evolved from a single species but then changed in response to their environment.
