UNIT 6
A regulatory protein that binds to the operator to block RNA polymerase from transcribing genes
A few companies in China and South Korea provide the service of cloning dogs, using cells from their clients’ pets to provide nuclei in procedures. Should their clients expect the clone to look identical to their original pet? Why or why not? What ethical question does this bring up?
No, because the DNA would be the same, but it may not be equally expressed. Differences in environment also contribute. In order to get 1 dog that survived, many dogs were created and died. Is it worth it for one animal to live when many are killed in the process?
What is RNA splicing?
When introns are removed and exons are conjoined.
What causes mutations?
A) Replication errors during DNA synthesis
B) Environmental factors such as radiation or chemicals
C) Viral infections
D) All of the above
D) All of the above
What aspect of the DNA molecule allows it to replicate a duplicate copy of itself?
Base pairing, because the two strands of DNA are complementary, since one strand serves as a template for new nucleotides in a new complementary strand.
