Exam 12: How Genes Work

In eukaryotes,transcription takes place in the _________ and translation takes place in the ________.

A group of DNA nucleotides that contains the information to produce a single protein is a:

Explain why mRNA must be processed before it leaves the nucleus.

If an mRNA codon reads UAC,its complementary anticodon will be:

Biologists have found that the genetic code is universal,that the same triplet codons code for the same amino acids in almost all living things.Explain how this can be considered evidence for evolution.

The molecule that carries each amino acid to its correct position along mRNA in the cytoplasm is:

The three nucleotide sequence on mRNA is called an anticodon.

All of the following occur in both prokaryotes and eukaryotes except:

During protein synthesis,_______________ occurs in the nucleus as a copy of DNA is made into mRNA,and ______________ begins in the cytoplasm,when mRNA associates with a ribosome.

A(n)____________ is a piece of DNA with a group of genes that are transcribed together as a unit.

The mRNA has a three-nucleotide sequence called a(n)_________,while the molecule transporting the amino acid has a complementary sequence called a(n)_______________.

What is RNA interference?

The primary RNA transcript is:

The use of information in DNA to produce proteins in the cytoplasm is ____________.

To turn genes off,a regulatory protein called a(n)__________ is bound to a regulatory site so that RNA polymerase is blocked.
