Answer:
In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis. In stage two, the pyruvate molecules are transported into the mitochondria. The mitochondria are the organelles known as the energy "powerhouses" of the cells
A, i think, hope this helps:)
Answer:
Only one chromosome from each pair randomly passed to the s*x cells during meiosis and leads to differences between the siblings.
In a study of the raw materials used for photosynthesis, the two molecules that would be studied are carbon dioxide and water. This is because they are the reactants of the process. Without these molecules the process of photosynthesis cannot happen.
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.
