To arrest all the transcriptional events at the same position on the DNA template, the sequence of the gene being transcribed must be known, and in the reaction mixture three rNTPs must be added except for the one where the transcription process need to be arrested.

rNTPs are the Ribonucleoside tri-phosphates. It is comprised of a ribose sygar joined to three phosphate groups. There are 4 types of rNTPs: rATP, rCTP, rUTP, rGTP. They are required for making the RNA strand from DNA.

Transcription is the process of synthesizing the RNA strand from the template DNA strand. The process occurs in the nucleus of the eukaryotic cells and in the nucleiod of prokaryotes.

The result is that the cell is less sensitive to subsequent stimuli, which affects the cell's capacity to respond to the hormone.

Receptors for Ion Channels

Specific ions can travel through a channel that opens in the plasma membrane when a ligand attaches to an ion channel receptor. This procedure necessitates the receptor's specific membrane-spanning region.

An exposed DNA-binding site on the protein is brought to the surface when the ligand binds to the internal receptor. Once within the nucleus, the ligand-receptor complex attaches to particular regulatory areas of the chromosomal DNA to encourage the start of transcription.

pine trees, redwoods, and conifers belong in gymnosperms plant group.

The gymnosperms are a clade of seed-producing crops that involves conifers, cycads, Ginkgo, and gnetophytes. They form the clade Gymnospermae, and the living members of this clade are known as Acrogymnospermae. The term gymnosperm is derived from the Greek compound word o, which literally means "nked seeds."

Gymnosperms are a small class of plants that do not flower and produce "nked seeds." This implies that the seeds are generated on the reproductive structure's surface rather than within it, as in fruit.

Conifers (pines, cypresses, and relatives) are by far the most numerous group of living gymnosperms, followed by cycads, gnetophytes (Gnetum, Ephedra, and Welwitschia), and Ginkgo biloba (a single living species). Gymnosperms are dioecious in about 65% of cases, but conifers are mostly entirely monoecious.

A subspecies is a population that has developed somewhat different physical and genetic characteristics from the rest of the species. A species is a group of interbreeding living beings with a lot of the same characteristics.

A population or set of populations that have the potential to freely breed with one another within and among themselves are technically referred to as species. This is an independently existing, naturally defined concept. On the other hand, subspecies are defined as subdivisions of a species that have unique characteristics.

A species is essentially the biggest group of organisms within which interbreeding results in viable progeny. The term "subspecies" is ill-defined and should be used with extreme caution because it calls for a deep understanding of the specific species in question as well as an understanding of the philosophical basis for its subspecies designation. Unlike the definition of a species, it is not always an intrinsic idea. A "breed" is typically a domestic population with limited genetic variation, as opposed to a subspecies.

The tendency of toxins to accumulate in top predators is called biological Magnification.

The term "biological magnification" is frequently used to describe the process by which certain substances, such as heavy metals or pesticides, enter lakes, rivers, and oceans and then move up the food chain in progressively higher concentrations as they are incorporated into the diet of aquatic organisms like zooplankton. These aquatic organisms may then be consumed by larger fish, larger birds, animals, or humans.

Fossilization can occur as a result of a variety of processes, such as permineralization, casts and moulds, authigenic mineralization, replacement and recrystallization, carbonization, and bioimmuration.

Any member of the zoological "tribe" Hominini (family Hominidae, order Primates), of which only one species—Homo sapiens, or humans—exists today, is referred to as a hominin. The word is most frequently used to refer to extinct members of the human lineage, including some that are now well recognized thanks to fossil evidence, such H. neanderthalensis (the Neanderthals), H. erectus, H. habilis, and numerous species of Australopithecus.

A particular mutated sequence may or may not distinguish an original amino acid sequence.

Quantitative measurement of net primary production (NPP) explains that the energy transferred to the next trophic has a different amount from the energy obtained in the previous trophic.

Net primary production or NPP is energy stored as biomass by plants. NPP is obtained from the calculation of gross primary productivity minus the rate of loss of energy for metabolism and maintenance.

Energy cannot be created, but can be changed from one form to another. Energy is only transferred from one trophic level to the next through the food chain. The energy transferred is NPP in the form of biomass at the first level which is then transferred to the next level when a consuming process occurs. Therefore the amount of energy transferred to the next trophic level is smaller than the energy available at the previous level because it has been reduced for metabolism and maintenance.

Wolves spread throughout most of north America and Eurasia through successive ice ages is true.

The wolf's species distribution is known as the wolf distribution (Canis lupus). Wolves were first seen in North America above the 15th parallel north and in Eurasia above the 12th parallel north. However, due to cattle predation and the fear of wolf attacks on humans, deliberate human persecution has restricted the species' range to only approximately one-third of its original size.

Due to legal protection, changes in land use, and the migration of rural humans to cities, wolf population decreases have been halted since the 1970s, and this has encouraged recolonization and reintroduction in some areas of its previous range. The species is still under threat from habitat fragmentation, human competition for livestock and game species, and worries about wolves' potential threat to people.

Despite these dangers, the IUCN Red List rates the grey wolf as Least Concern due to its relatively large range and steady population.  The African golden wolf (Canis lupaster), which lives north of the Sahara, and the Ethiopian wolf (Canis simensis), which lives in Ethiopia, make up the majority of the continent's wolf population.

We are able to distinguish between the hba (Hemoglobin beta globin) allele and the hbs alleles in our lab because HbA allele produces shorter PCR product than HbS.

Sickle hemoglobin (HbS) is caused by a point mutation in the two subunits of normal hemoglobin (HbA), resulting in nucleated polymerization and pathology.

There are at least two variants (or alleles) of the HBB gene: HbA and HbS. The HbA allele provokes no problems. The HbS variant can result in either sickle cell trait or sickle cell disease. This allele tends to cause red blood cells to "sickle" rather than forming donut shapes.
