Answer:
Scientific method is not developed in the 1800s
Answer:
(E) None of the above
Explanation:
All of the answers contribute to the high fidelity of DNA synthesis.
Accuracy of the DNA replication is achieved thanks to various mechanisms such as:
- DNA polymerase activity (high processivity)-ability of the enzyme to copy long stretches of DNA
- DNA polymerase proofreading-ability to recognize its own mistakes and fix them
- Cell's surveillance-cell monitors its DNA status, checks for the damage
- Mismatch Repair-cell contain repair machinery which recognizes DNA helix deformities, removes and replaces the portion containing the mismatch etc.
Deletions occur when a chromosome breaks and some genetic material is lost. Deletions can be large or small, and can occur anywhere along a chromosome.
Answer:
The precambrian would finish in mid-november, the paleozoic would end in mid-december, humans would show up at the end of December.
Explanation:
The precambrian period is the longest period in terms of earth's formation and development of several species. The paleozoic (belongs to the cambrian period) is a continuation of the previous era with other species that devedloped in the seas. Human evolution is actually short and brief in terms of prehistoric geological registry, as humans appeared much more towards the end in earth's prehistoric registry (the end of the cenozoic).
