Confirm that the sample has both helicase and primase activities, but not the ability to synthesize DNA
- The replisome is a multiprotein-RNA complex that is required for the replication of DNA. The replisome consists of different proteins which include:
1. Helicase enzymes that unwind and separate the DNA strand
2. Replication factor C (RFC), a DNA-dependent ATP that acts as an activator of DNA polymerase.
3. Proliferating cell nuclear antigen (PCNA)
4. DNA gyrase/topoisomerase that cuts and reseals DNA strands, which is essential for DNA synthesis.
5. Primase enzyme that synthesizes short RNA fragments called primers.
6. DNA polymerase III, an enzyme that catalyzes the polymerization of deoxyribonucleotides into a DNA strand.
7. DNA ligases enzymes that form phosphodiester bonds at a single-strand break in DNA
- A primosome is a multiprotein complex responsible for creating RNA primers on single-stranded DNA (ssDNA) during the replication process.
- The primosome is composed of different primase and helicase enzymes. In<em> Escherichia coli</em>, it consists of PriA helicase, PriB, PriC, DnaB helicase, DnaG (encoded by the dnaG gene), DnaC and DnaT primase.

How was the naming of organisms different before carolus Linnaeus: Before Linnaeus came up with a standardized system of naming, there were often many names for a single species, and these names tended to be long and confusing. Linnaeus decided that all species names should be in Latin and should have two parts. Remember, this 2-part system is called binomial nomenclature///////.
Natural selection ensures that animals with features that increase their chances of survival are more likely to live and pass those traits on to their progeny.
Animals adapt to their surroundings over a lengthy period of time, which causes those changes. The evolution of adaptations happens across many generations.
<h3>What is an adaptation?</h3>
- A physical or behavioral characteristic of an animal that enhances its ability to survive in its environment is known as an adaptation.
- To put it another way, an adaptation is something a species does or has on them that makes it easier for them to locate food, water, mates, and shelter.
- Among the adaptations that helped animals live and prosper on land are:
- Gas exchange using a moist membrane
- The ability to traverse land (limbs instead of fins)
- The capability of body water conservation
- The capability of reproduction and early habitability
- The capacity to endure fast environmental changes
<h3>What are the types of adaptation?</h3>
Depending on the environment, there are three basic types of adaptations: behavioral, structural, and physiological.
- Physiological- When an animal's body's internal mechanisms adapt to its surroundings.
- Structural - Over the course of millions of years of evolution, the animal's bodily features alter.
- Behavioral - Animals adjust their behavior in reaction to their environment.
