Many pathways involve second messengers, small, non-protein molecules that pass along a signal initiated by the binding of a ligand (the “first messenger”) to its receptor.

Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events, most commonly protein phosphorylation catalyzed by protein kinases, which results in a cellular response. Proteins that detect stimuli are commonly referred to as receptors, though the term sensor is also used in some cases. The changes caused by ligand binding (or signal sensing) in a receptor initiate a biochemical cascade, which is a chain of biochemical events known as a signaling pathway. When signaling pathways interact with one another, they form networks that allow cellular responses to be coordinated, often through combinatorial signaling events.

Transcription is the process by which genetic information encoded in DNA is copied into a complementary RNA molecule. It involves several molecules and occurs in the nucleus of eukaryotic cells or the cytoplasm of prokaryotic cells. The process of transcription can be divided into three main steps: initiation, elongation, and termination.

1. Initiation:

Initiation is the first step of transcription, where the RNA polymerase enzyme binds to a specific region of the DNA called the promoter. In eukaryotic cells, additional proteins known as transcription factors assist in the binding of RNA polymerase to the promoter. Once the RNA polymerase is bound, it unwinds a small portion of the DNA helix to expose the template strand. The template strand serves as a template for the synthesis of a complementary RNA molecule.

2. Elongation:

During the elongation step, RNA polymerase moves along the DNA template strand, synthesizing an RNA molecule that is complementary to the template. It adds nucleotides to the growing RNA molecule in a 5' to 3' direction. As the RNA polymerase moves forward, the DNA helix reforms behind it. The newly synthesized RNA molecule forms base pairs with the exposed DNA template, forming a temporary RNA-DNA hybrid.

3. Termination:

Termination is the final step of transcription, where the RNA polymerase recognizes a termination signal on the DNA template. In prokaryotic cells, termination signals may involve specific DNA sequences or the formation of RNA secondary structures. When the termination signal is encountered, the RNA polymerase dissociates from the DNA template, and the newly synthesized RNA molecule is released. In eukaryotic cells, termination is more complex and involves additional factors.

The molecules involved in transcription include:

- RNA polymerase: This enzyme synthesizes the RNA molecule by adding nucleotides to the growing RNA chain.

- DNA template: One of the DNA strands, known as the template strand, serves as a template for the synthesis of the complementary RNA molecule.

- Nucleotides: These are the building blocks of RNA and are added by RNA polymerase to the growing RNA chain.

- Transcription factors (eukaryotes): These proteins assist in the binding of RNA polymerase to the promoter region and regulate the initiation of transcription.

- Termination signals: These DNA sequences or structures signal the end of transcription.

In eukaryotic cells, transcription occurs in the nucleus, where the DNA is located. After transcription, the RNA molecule undergoes processing, including the removal of introns and the addition of a protective cap and a poly(A) tail, before it is transported to the cytoplasm for further processing or translation into proteins. In prokaryotic cells, transcription occurs in the cytoplasm since they lack a distinct nucleus.

Different types of cells look and function differently, the basis for these differences is DIFFERENT PATTERNS of gene expression. This process (differential gene expression) leads to cell specialization.

Gene expression refers to the process by which the genetic information flows from a DNA sequence (i.e., a gene) to an mRNA molecule and finally to a protein.

In somatic (body) cells, the differential patterns of gene expression lead to the generation of different proteins and ultimately to different types of cells (cell phenotypes).

In biological systems, the basic flow of genetic information is sometimes represented with a flowchart known as "the central dogma" (image is attached). Transcription converts DNA information into RNA, while translation converts RNA into proteins. Reverse transcription and replication are two more examples of techniques for the spread of information in various forms. The techniques by which regulatory signals travel between the many layers of molecule types shown in the model and how information is encoded are not, however, directly addressed by this system.

They would compete with native snake species for resources, causing a decline in native snake populations and possibly extinction. Hence option D is correct.

Predators are living things that go after and kill prey. Both carnivores and omnivores can be predators. Predation can be classified into four categories: carnivory, herbivory, parasitism, and mutualism. Depending on whether or not the victim dies, each sort of predation can be classified.

Predators include weasels, hawks, wolves, mountain lions, and grizzly bears. Because they are carnivores, predators only eat meat.
