DNA replication M
Explain the process of DNA replication.
DNA replication is when the cell makes an identical copy of its DNA.
What are the building blocks of DNA
adenine (A), thymine (T), guanine (G), and cytosine (C).
What is the fossil record?
The fossil record is a collection of fossils documenting the history of life on Earth.
Describe the role of enzymes involved in DNA replication.
Helicase unwinds the double helix structure of DNA, while polymerase synthesizes new DNA by adding complementary nucleotides. Ligase helps tie up the new nucleotides together like glue.
Describe the shape of DNA molecule and how it helps store genetic information
Duplication of the genetic information occurs by the use of one DNA strand as a template for formation of a complementary strand.
What evidence from the fossil record supports the theory of evolution?
Differentiate between DNA replication in prokaryotic and Eukaryotic cells.
Eukaryotic DNA replication requires multiple replication forks, while prokaryotic replication uses a single origin
How does the sequence of nucleotides in DNA determine an organism's traits?
It determines the order of amino acids in one or more proteins.
Can you describe the process of fossilization?
After a bone, wood fragment, or shell is buried in sediment, it may be exposed to mineral-rich water that moves through the sediment. This creates the fossilization.
Compare and contrast mitosis and meiosis, focusing on key stages.
In meiosis, prophase, metaphase, anaphase, and telophase occur twice. The first round of division is special, but the second round is more like mitosis. In mitosis, prophase, metaphase, anaphase, and telophase occur once.
What is the role of genes in the genetic code?
It tells a cell how to make a specific protein.
How has discovering fossils in different parts of the world contributed to our understanding of continental drift?
Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents.
