Describe how the two tools of molecular biology—often described as scissors and glue—are used in conjunction with plasmids to make copies of a gene of interest.
Restriction enzymes act as molecular scissors producing cuts at or near sequence specific regions (i.e, restriction sites) at both the strands of a double stranded DNA molecule. On the other hand, DNA ligase enzymes act as molecular glue and help in joining the fragmented DNA pieces together by forming phosphodiester bonds.
What are restriction enzymes?
Restriction enzymes are naturally found in bacterial and archaebacterial cells. Such enzymes protect these unicellular cells by cleaving and destroying foreign genetic particles injected by bacteriophages (i.e, viral molecules responsible for infecting bacterial cells). Classically, there are four types of restriction enzymes i.e, types I, II, III and IV. Example: EcoRI, EcoRII, HindIII, etc.
What is DNA ligase?
DNA ligase, a specific kind of enzyme helps in connecting fragmented DNA strands by facilitating the creation of a phosphodiester bond. It helps the cells to repair single-strand breaks in their duplex DNA, while other varieties (like DNA ligase IV) may only repair double-strand breaks (i.e. a break in both complementary strands of DNA). DNA ligase uses the corresponding strand of the double helix as a template to repair single-strand breaks, producing the last phosphodiester bond necessary to finish the repair of the DNA. Thus, both DNA replication and DNA repair need DNA ligase. Example: T4 DNA ligase, E.coli DNA ligase, etc.
What is molecular cloning?
In this process, a particular gene of interest or the insert can be introduced into a plasmid vector by producing a cut at both the vector and the gene with the same enzyme thus, producing sticky ends and ligating the two fragmented pieces together to produce a recombinant product.
What is the role of the restriction enzymes in molecular cloning?
The isolated DNA has to be incubated with the specific restriction enzymes under optimal conditions.This helps the restriction enzymes in producing sequence specific cuts at specific restriction sites in the DNA molecules. This catalytic reaction is called restriction digestion.Agarose Gel Electrophoresis helps in analyzing the progression of the restriction digestion reactions.On the other hand, the plasmid vector DNA also has to be processed using similar procedures.What is the role of the DNA ligase enzymes in molecular cloning?
Ligation is the process of fusing the two DNA fragments together with the enzyme, DNA ligase.The interest molecule and the vector are combined to create the final DNA molecule. As a result, the new hybrid DNA molecule is also referred to as a recombinant DNA molecule, and the technique is known as recombinant DNA technology.To know more about Phosphodiester bond, please click here https://brainly.com/question/23660733

Restriction enzymes are considered as scissors that cleave DNA into fragments at or near specific recognition sites. DNA ligases act as a glue that helps in joining the DNA strands together by catalyzing the formation of a phosphodiester bond.
What are restriction enzymes?
These are protein isolated from bacteria that cleaves DNA sequences at sequence-specific sites, producing DNA fragments with a known sequence at each end. It helps in recombinant DNA technology and genetic engineering.
What are the DNA ligases?
It is a specific type of enzyme that plays a role in, maintaining genomic integrity by repairing single-strand breaks in duplex DNA in living organisms.
In the gene cloning process, Both the plasmid and the DNA sequence of interest are cut with restriction enzymes to generate compatible overhang sticky ends that allow them to bind. The enzyme DNA ligase joins the fragments with matching ends together to form a single, unbroken molecule of DNA. This produces a recombinant plasmid that contains the target gene.
Hence restriction enzymes act as molecular scissors and ligases act as a molecular glue.

What is the role of epinephrine in cell signaling?
Epinephrine plays a crucial role in the fight-or-flight response as a cell signaling chemical.
What is cell signaling?
Chemical signals are frequently used by cells to communicate. These chemical signals, which are proteins or other compounds made by the transmitting cell and released into the extracellular space, are frequently secreted by the cell.
Role of epinephrine in cell signaling:
An essential cell signaling molecule in the fight-or-flight response is epinephrine. Epinephrine, also referred to as adrenaline, is a powerful messenger that signals various cell types throughout the body with a variety of effects. Epinephrine binds to receptors on smooth muscle cells that surround the bronchioles in the lungs. As a result of the muscles relaxing, the bronchioles widen, allowing more oxygen to enter the bloodstream. Epinephrine causes the pacemaker cells of the sino-atrial node of the heart to beat more quickly. This speeds up the flow of oxygen, glucose, and other chemical signals to the cells that require them. Additionally, epinephrine constricts particular subcutaneous muscle cells, resulting in beads of sweat and raised hairs on the skin's surface.Hence epinephrine plays a crucial role in cell signaling.

Why are soft-bodied organisms less likely to leave a fossil trace than hard-bodied organisms?.
Proteins are soft-bodied organisms less likely to leave a fossil trace than hard-bodied organisms.
soft-bodied organisms are much more likely to decay than organisms with difficult body elements along with bones, shells or enamel. as a consequence the fossil document consists of many stays of creatures like fish, clams and mammals, and relatively few stays of creatures like jellyfish, earthworms or wild flora.
Animals with difficult shells and skeletons are represented nicely within the fossil record. alternatively, soft-bodied animals are probable represented very poorly. it is possibly that maximum gentle-bodied species that ever existed are long gone all the time with out a trace. Land animals are probable very poorly represented as nicely.
The maximum not unusual approach of fossilisation is petrification through a system called permineralisation.
