Endocytosis DNA replication: 1 helicase separates the two strands of the double helix to expose the nitrogenous bases. Specific proteins, including DNA polymerase, then synthesize a complementary daughter strand of Before replication can occur, the length of the DNA double helix about to be copied must be unwound. Once the DNA strands have been unwound, they must be unzipped to expose the bases so that new Copying occurs at a localized region called the replication fork, which is a Y shaped DNA replication occurs during the synthesis S phase phase of interphase in the cell cycle.

Compare DNA replication in prokaryotes with that of eukaryotes. Lesson Summary Copying the Code Each strand of the double helix has all the information needed to reconstruct the other half by the mechanism of base pairing. Because each strand can be used to make the other strand, the strands are said to be complementary. Eukaryotic cells have much more DNA. Nearly all of it is contained in chromosomes, which are in the nucleus. Copying the Code 1. Why are the strands of a DNA molecule said to be complementary? Because each strand can be used to make the other strand. What is the first step in eukaryotic DNA replication? The strands of the double helix separate, or unzip. What enzyme joins individual nucleotides to produce the new strand of DNA? DNA polymerase Lesson All Rights Reserved.

A replication fork is a point in a DNA molecule where the two strands separate during replication. Does DNA replication take place in the same direction along both strands of the DNA molecule that is being replicated? Explain your answer. Hint: Look at the illustration of DNA replication in your textbook. DNA replication proceeds in opposite directions between replication forks. Make a sketch of the double helix of DNA. Show how it unzips for replication and how complementary strands are built. Label the nitrogenous bases, replication fork, DNA polymerase, the original strand, and the new strand. Labels should include nitrogenous bases, replication fork, DNA polymerase, original strand, and new strand.

Is DNA replication always a foolproof process? Although many proteins check the DNA for damage or errors, damaged regions can still be replicated. This may result in gene alterations and serious complications for the organism. Why is the pairing of bases during replication essential for the transmission of inherited traits from parent to offspring? The match is nearly always perfect between A and T and G and C, so that the code is copied correctly every time.

The DNA molecule separates into two strands during replication. And 20 percent of American adults actually sunbathe—that is, they deliberately expose their skin to solar radiation. This poster presents information everyone should know. What is ultraviolet radiation? How can you protect yourself from UV radiation? These sunscreen ingredients block UVA radiation. How many types of ultraviolet radiation are there? What are they? Which one do you think that is? I have nothing to worry about. She is wrong. The fact that her skin seems fine now is irrelevant because damage done now will not become evident for many years. Besides, more frequent sun exposure now results in a higher risk of skin damage later. There is no such thing as a safe tan. Do you think that skin cancer can be inherited? Why or why not? Skin cancer is caused by damage to the DNA in adult skin cells, which would not be passed along to any offspring.

Parallel lines and transversals activity DNA replication is the process where your cells create exact copies of their genetic code. To do this, your cells rely on the nucleotides that make up your DNA.
