approximately what percentage of the atp formed by the reactions of glycolysis is produced by substrate-level phosphorylation? * 10 points a) 0% b) 2% c) 10% d) 38% e) 100%
Substrate -level phosphorylation accounts for approximately 100% of the ATP formed by the reactions of glycolysis.
The direct transfer of a phosphate group to ADP to form ATP is known as substrate-level phosphorylation. It accounts for all of the ATP produced by glycolysis reactions. The first substrate-level phosphorylation occurs when 1,3-diphosphoglyceraldehyde is converted to 1,3 diphosphoglyceric acid and 2 NADH2, resulting in the formation of 6 ATP. Substrate-level phosphorylation converts the 1, 3-diphosphoglyceric acid to 3 phosphoglyceric acid, which produces 2 ATP. The second substrate-level phosphorylation takes place when phosphoenolpyruvic acid is converted to pyruvic acid, which results in the formation of two ATP molecules.

The basal ganglia are thought to elicit movement via disinhibition of thalamic neurons (va/vl).
The term "basal ganglia" describes a collection of subcortical nuclei that play a variety of tasks, including motor learning, executive behaviors, and emotions in addition to their primary job of controlling movement. The putamen, globus pallidus, caudate nucleus, subthalamic nucleus, and substantia nigra are the other four pairs of nuclei that make up the basal ganglia. For a very long time, it has been considered that thalamic neurons fire in burst mode during sleep and unconsciousness and in tonic mode during perceptive states. However, new research indicates that bursts could also be important for the encoding of sensory data.

The rate of transcription for a gene is found to be affected by a mutation. Where would you expect the mutation to appear on the dna?.
Mutations can occur in germ-line cells or somatic cells.
How does mutation affect transcription?When DNA harm in the transcribed strand of an active gene is bypassed by an RNA polymerase, it can miscode at the destruction site and produce mutant transcripts. This procedure known as transcriptional mutagenesis can lead to the production of mutant proteins that could be important in tumor development. The effect of a frameshift mutation is the complete alteration of the amino acid course of a protein one form of mutation is a point mutation, in which a single base is changed.

The interphase lasts longer, occupying 90% to 95% of the lifetime of most cells.
What happens in interphase?In interphase, proteins and enzymes are created first to copy the cell's DNA, which is necessary for proper cell division, and then to permit mitosis, which is the process by which cells divide. These procedures need a lot of cellular energy and must proceed smoothly, which necessitates patience and accuracy. Once cell division begins, the majority of cellular activity are paused, allowing the cell to successfully divide into two while disregarding other tasks.
During this period, which nature has made relatively brief, the cell is fairly sensitive, resulting in the production of two brand-new, fully developed, healthy daughter cells that are identical to the parent cell.

Cells move to new positions as an embryo establishes its three germ-tissue layers during _____.
Cells move to new positions as an embryo establishes its three germ-tissue layers during embryogenesis.
During embryogenesis, the three germ layers—the ectoderm, mesoderm, and endoderm—form from the innermost layer, the hypoblast. Cells move through a process of gastrulation to establish the germ layers. The ectoderm gives rise to the nervous system and the epidermis, the mesoderm gives rise to the muscles, skeleton, and circulatory system, and the endoderm gives rise to the digestive and respiratory systems.
Cells must move to specific locations within the embryo in order to form the correct tissue type. For example, skin cells must be in the ectoderm layer, and muscle cells must be in the mesoderm layer. This movement of cells is known as cell migration.

This resistance is transmitted not only vertically, but also between species. Plasmids are extrachromosomal genetic elements found in many strains of bacteria.
They are small circular DNA molecules that replicate independently on the bacterial chromosome. Plasmids are mainly found in bacteria, Achaea, and other multicellular organisms.

Answer:
the answer is transposes.
Explanation:
Transposons, also called transposable elements, are mobile genetic elements that generally have only modest target site selectivity and can thus insert themselves into many different DNA sites. In transposition, a specific enzyme, usually encoded by the transposon and called a transposase, acts on a specific DNA sequence at each end of the transposon—first disconnecting it from the flanking DNA and then inserting it into a new target DNA site. There is no requirement for homology between the ends of the element and the insertion site.
Most transposons move only very rarely (once in 105 cell generations for many elements in bacteria), and for this reason it is often difficult to distinguish them from nonmobile parts of the chromosome. In most cases, it is not known what suddenly triggers their movement.
On the basis of their structure and transposition mechanisms, transposons can be grouped into three large classes (Table 5-3), each of which is discussed in detail in subsequent sections. Those in the first two of these classes use virtually identical DNA breakage and DNA joining reactions to translocate. However, for the DNA-only transposons, the mobile element exists as DNA throughout its life cycle: the translocating DNA segment is directly cut out of the donor DNA and joined to the target site by a transposase. In contrast, retroviral-like retrotransposons move by a less direct mechanism. An RNA polymerase first transcribes the DNA sequence of the mobile element into RNA. The enzyme reverse transcriptase then transcribes this RNA molecule back into DNA using the RNA as a template, and it is this DNA copy that is finally inserted into a new site in the genome. For historical reasons, the transposase-like enzyme that catalyzes this insertion reaction is called an integrase rather than a transposase. The third type of transposon in Table 5-3 also moves by making a DNA copy of an RNA molecule that is transcribed from it. However, the mechanism involved for these nonretroviral retrotransposons is distinct from that just described in that the RNA molecule is directly involved in the transposition reaction.
