He developed the principle of biological succession.

Answers

He formalized many principles of geology. Charles Lyell was a famous geologist of his era. One of his important works was the book Principles of Geology, an exploration of James Hutton's uniformitarianism doctrine. He also supported Darwin's theory of natural selection.

Which of these best describes the role of helicase and DNA polymerase in DNA replication? *A. DNA polymerase "unzips" the DNA strand, while helicase brings in new strands of DNA to match the old strands

B. Helicase attaches new nitrogen bases to the ends of old DNA strands, while DNA polymerase breaks down unused DNA strands

C . DNA polymerase breaks down the old strand of DNA after a new one has been replicated, while helicase connects the two DNA strands together

D. Helicase "unzips" the DNA strand, while DNA polymerase brings in new strands of DNA to match the old strands

Answers

'Helicase "unzips" the DNA strand, while DNA polymerase brings in new strands of DNA to match the old strands.' best describes the role of helicase and DNA polymerase in DNA replication. The correct option is d.

Helicase is essential for DNA replication because it "unzips" the double-stranded DNA molecule. In order to separate the two strands and create a replication fork this process involves severing hydrogen bonds between the base pairs. On the other hand, DNA polymerase is charged with the vital task of creating new DNA strands.

It does this by incorporating complementary nucleotides into the template strands already present. This maintains genetic fidelity by ensuring that the newly formed strands mirror the original ones. The precise duplication of genetic information which is necessary for cell division and inheritance, depends on the interaction between the unwinding action of the helicase and the strand-building activity of DNA polymerase.

In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.

What did Chargaff discover while studying bases in the DNA of organisms? The bases in the DNA of each organism were unique. The ratios of thymine and adenine were similar, as were the ratios of guanine and cytosine. The overall percentages of bases were different from one organism to the next. There were equal amounts of all four bases in every organism, or 25 percent of each base.
