gregori [183]

Answer:

Codon: 3'-CGC-5'

Codon: 3'-UGC-5'

Explanation:

The anticodons of tRNAs bind to the complementary codons of mRNA. The mRNA codons are always read in 5' to 3' direction. The 5' base of an mRNA codon pairs with 3' base of the anticodon of tRNAs. The first base of the anticodon (the  5' base) determines the number of mRNA codons that are recognized by the tRNA. When the 5' base of the tRNA anticodon is U or G, it binding with codon is less specific. A tRNA anticodon with 5’ G base can read two different codons.  

Anticodon:  5'–GCG–3'.

Codon: 3'-CGC-5'

Codon: 3'-UGC-5'

An example of a false negative is taking an HIV test and having the test come back negative to say the patient is clean, but in reality they have HIV. Another example of a false negative is a woman taking a pregnancy test saying "not pregnant" (i.e. test is negative), but she actually is pregnant. Between those two examples, it is better to have a false negative pregnancy test because it is non life threatening.

A false positive example would be getting bad news you have cancer, when you actually don't have cancer. Another false positive example is a test saying you have a cold virus, when in actuality you don't. The first example mentioned would have the patient likely go through intense chemo treatments which would greatly affect their livelihood. The second example is a more harmless false positive as it would involve at most a flu shot if anything.
