The mechanism of gene expression initiates with the process of transcription in which the genetic information in the DNA is into genetic codes in the form of messenger RNA.
<h3>What is the process of gene expression followed by transcription?</h3>
The process of gene expression followed by transcription is processed through the messenger RNA which then undergoes some processing such as modification of tails and removal of non-coding sequences before the genetic codes are translated to their respective amino acids in a process known as translation.
The amino acids are typically associated together by peptide bonds and the resulting primary protein structure is folded in specific ways depending on their functions.

Answer:
True.
Explanation:
The lac repressor is a molecule that is part of the regulation of genes to metabolize lactose to some bacteria, including Escherichia coli. Bacteria need to metabolize lactose to provide energy to your body, in which case the lac repressor acts as a lactose detector, preventing the genes responsible for lactose metabolism proteins from being activated unnecessarily, thereby preventing lactose digestion. The lac repressor has the opposite function to the lac operon, which stimulates lactose digestion.
However, for some time, it was unclear whether lac repressor inhibits lac operon transcription by inhibiting RNA polymerase binding to its promoter or allowing transcription to begin, but blocking elongation after the bound repressor site.
It is now recognized that lac repressor paralyzes enzyme production in the absence of lactose, and catabolic activator protein (CAP), which aids in the production of glucose in the medium.
Answer: Wildlife biologists are important to the safety and preservation of animal species, but they also benefit society as a whole. They observe animals in their natural habitats and conduct experimental studies to test for environmental hazards, diseases and unusual movement patterns.

Yes, The desert relies on precipitation from weather patterns while the rain forest can create its own precipitation.
Answer:
Only one species can fill an ecological niche because each niche is destined exclusively for each species, since its structure, physiology and behavior determine it.
Explanation:
An ecological niche is the way in which each species relates to its environment, to other species and takes advantage of the resources available for its development, being an exclusive and individual characteristic of that species.
The ecological niche is a concept that many consider abstract, since it is unique for a species. Each species has a physical structure, functioning and behavior that differentiates it from the others, which leads it to occupy a certain place within an ecosystem, which would be its ecological niche.
