The S phase (Synthesis phase)
DNA replication takes place during the S-phase of interphase, creating two identical sets of DNA. The DNA coils and condenses into units known as chromosomes during the start of mitosis. The two identical sister chromatids that make up each chromosome are joined by a centromere.How does DNA replication work?The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication.
A double helix of two complementary strands makes up DNA. These strands are split apart in the replication process. The method of semi-conservative replication uses each strand of the original DNA molecule as a template to create its counterpart.
Several enzymes that carry out this process are given below, along with their activities.
____________
DNA Dependent DNA POLYMERASE is a class of enzymes that is responsible for all organisms' DNA replication processes. It accelerates DNA replication in the 5′ to 3′ range.The enzyme known as TOPOISOMERASE is involved in the over- or under-winding of DNA.HELICASE—Using the energy from ATP hydrolysis, which is characterized by the breakdown of hydrogen bonds between annealed nucleotide bases, helicases are frequently employed to separate the strands of a DNA double helix or a self-annealed RNA molecule.DNA GYRASE, a particular kind of topoisomerase, relieves strain caused by DNA helicase's unwinding action.DNA LIGASE- Joins the OKAZAKI FRAGMENT of the lagging strand and re-anneals the semi-conservative strands.PRIMASE - Primase catalyzes the production of a short primer, which is a ssDNA template-specific piece of RNA (or DNA in other species).REPLICATION FORK -(Attachment #1)
_________________
REPLICATION PROCESS -
INITIATION - The beginning of DNA replication takes place at certain locations in the DNA molecule known as ori-sites or regions. Enzymes often recognize these locations and initiate the process. As opposed to C-G base pairs, which produce three hydrogen bonds, A-T base pairs only form two hydrogen bonds, making them easier to strand split. As a result, these sites are typically "AT-rich" (rich in adenine and thymine bases). Following the discovery of the origin, enzymes create a pre-replication complex that unzips the double-stranded DNA. The enzyme topoisomerase is involved in this process.Elongation - The 5'-3' activity of the DNA polymerase enzyme. Now, a new strand was created by DNA polymerase enzymes in the direction of 5′ to 3′ (note: the DNA template is read in 3' to 5' direction). RNA primers were simultaneously created by the primase enzyme and utilized by the polymerase to create new strands of RNA.As DNA polymerase enzyme has 5′ - 3′ direction so two types of strand are form -
LEADING STRAND - A DNA polymerase with high processivity that has the direction 5′ - 3′ (template strand 3′-5′) extends the continuous strand from the primer in the same direction as the replication fork that is expanding. One RNA primer is applied to the leading strand.
LAGGING STRAND - It is the discontinuous strand whose synthesis is going in the opposite direction of the replication fork that is developing. Each primer extends the lagging strand intermittently to create Okazaki fragments. A low processivity DNA polymerase that is different from the replicative polymerase enters to fill the gaps after RNase eliminates the priming RNA pieces. Multiple primers are applied to the lagging strand, and then the Okazaki fragments are joined by the ligase enzyme, filling in the gaps.
TERMINATION - Replication forks meet and end at several locations throughout the chromosome because eukaryotes start DNA replication at various locations; it is unknown how these are controlled. Termination necessitates the halting or blocking of the DNA replication fork's forward motion. When termination occurs at a particular locus, it includes the interaction of two elements: (1) a DNA sequence known as a termination site sequence, and (2) a protein that binds to this region to actually cease DNA replication.

Answers
The geochemical cycle that is least likely to be affected by global warming is the water cycle, because even as temperatures increase, the evaporation cycle will remain the same.
How to describe the water cycle?at the beginning — liquid: water is present in the transpiration of living beings, in addition to rivers, lakes, oceans, etc. in the middle — gaseous: this water evaporates and accumulates, to later condense in the cloudsat the end — liquid: the precipitation of water that returns to Earth in the form of rain occurs, restarting the cycle.With this information, we can conclude that the water cycle, also known as the hydrological cycle, refers to the continuous movement that water makes through the physical environment and the living beings of the ecosystem, passing through the atmosphere, hydrosphere, lithosphere and biosphere.

What was the problem with this genetic engineering solution
Answers
The potential for greater economic disparity and higher human misery, as well as the potential for extensive eugenics programs and dictatorial control over human life, are among the social and political concerns of genetic engineering. In certain situations, moral danger overrides technological risk without a doubt.
What is genetic engineering?Genetic engineering, often known as genetic alteration, is a technique that modifies an organism's DNA using technology developed in labs. This could entail altering a single base pair (A-T or C-G), erasing a section of DNA, or incorporating new DNA.
Millions of workers will be out of work in a few years if multinational businesses decide to replace the national products of Third World nations with their own biotechnology compounds. And the unintended result is guaranteed, not possible, or likely if governments decide to create racial programs and monitoring systems based on genetic engineering advances. The risk is not that the decision-makers underestimated the effects of their decisions, but rather that they act in an unethical manner.

Greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals
What increases stroke volume?A greater force of contraction consequently increases the volume of blood ejected with each systole (Systolic Volume). Increasing the stroke volume also increases, as a consequence, the cardiac output (CO = VS x HR).
With this information, we can conclude that greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals

5. Draw conclusions: Natural selection is the process by which favorable traits tend to increase in frequency over time. How does this experiment illustrate natural selection
Answers
Natural selection is usually defined as the process by which forms of life having traits that better enable them to adapt to specific environmental pressures, as predators, changes in climate, or competition for food of mates, will tend to survive and reproduce in greater number than others of their kind, thus ensuring the perpetuation of those favorable traits in succeeding generations. Charles Darwin and Alfred Wallace developed the theory of evolution by natural selection and jointly presented papers on the subject in 1858. It is based on the finding that some distinctions between people in a group can be passed down across generations. Darwinism, or Darwin's theory, is a theory of evolution created by Charles Darwin stating that all life forms arise, change and develop from a process of natural selection. Natural selection is the process of changes in evolution due to the survival of certain individuals in a species. It is one of the most important parts of the theory of evolution. Darwin's idea provided a straightforward yet persuasive explanation for the diversity of species on Earth. Because various locations have distinct circumstances and survival possibilities, natural selection selects the organisms that are best adapted to that particular environment.
