DNA copies itself through the process of replication: You can add this document to your study collection s Sign in Available only to authorized users. What is ultraviolet radiation? This poster presents information everyone should know. What is a replication fork? Name Class Date The DNA molecule separates into two strands during replication.
Label both drawings with the following terms: Warning Signs of Skin Cancer The skills used in this activity include creativity and intellectual curiosity, information and media literacy, and social responsibility. What is ultraviolet radiation? Complete the chart by writing a strategy to help you remember the meaning of each term. The diagram below shows the replication of DNA. The poster on the previous page was intended to educate people about how UV radiation in sunlight damages skin cells and show them how they can avoid exposure to UV.
Add this document to collection s. Evaluate booklets based on the accuracy of the information, whether it is presented in an easy-to-read and easy-to-understand format, and creativity. Besides, more frequent sun exposure now results in a higher risk of skin damage later. Each time a chromosome is replicated, some DNA may be lost from the tip of the chromosome, or telomere.
Is DNA replication always a foolproof process? Look at the diagram of DNA Replication in your textbook. As you work through this lesson, you may find these terms hhomework the activities.
Your e-mail Input it if you want to receive answer. The jobs of some enzymes are listed below. How can you protect yourself from UV radiation?
12.3 DNA Replication
In prokaryotes, DNA is replidation circular molecule that is free in the cytoplasm. The fact that her skin seems fine now is irrelevant because damage done now will not become evident for many years.
Compare DNA replication in prokaryotes with that of eukaryotes. You can add this document to your study collection s Sign in Available only to authorized users.
Copying the Code 1. Label one diagram as Prokarytic DNA.
What enzyme joins individual nucleotides to produce the new strand of DNA? The center of the DNA strand exhibits base pairing. What is a replication fork? For complaints, use another dnw. A n DNA strand opens to make new strands. I have nothing to worry about. Why is the pairing of bases during replication essential for the transmission of inherited traits from parent to offspring?
Labels should include nitrogenous bases, replication fork, DNA polymerase, original strand, and new strand. And 20 percent of American adults actually sunbathe—that is, they deliberately expose their skin to solar radiation.
Complete the chart by writing a strategy to help you remember the meaning of each term. Use Internet and library resources to research the warning signs of skin cancer and what a person who detects one or relpication of these warning signs should do.
What enzyme makes it less likely that DNA will be lost from telomeres during replication? Add this document to saved. The poster on the previous page was intended to educate people about how UV radiation in sunlight damages skin cells and show them how they can avoid exposure to UV.
Then, as you read Lesson 3, find the answers to your questions.
For some people, though, these warnings come too late. Add to collection s Add to saved. Name Class Date The diagram below shows the replication of DNA.
Because each strand can be used to make the other strand.
