Exam 15: From Gene to Protein

The ____________________ is a sequence of DNA where RNA polymerase binds to begin transcription.

As transcription begins, RNA polymerase binds to a segment of a gene called a(n)

Which of the following is not a feature of the genetic code?

The process depicted in the figure below takes place in

In humans, the herbicide atrazine helps RNA polymerase bind to the promoter of the gene for the enzyme aromatase. As a result,

In tRNA, an amino acid is covalently bonded to an anticodon.

Which of the following results would most likely occur if introns were not removed from newly made mRNA?

Insertion or deletion mutations can cause a ____________________ that causes a change in the reading of the mRNA codons.

Ribosomal RNA plays a role in the formation of the covalent bonds between amino acids during translation.

If X is a base that is inserted into each of the following DNA sequences, on which of them is it most likely to have the greatest affect on the gene's protein product?

Proteins are produced directly from DNA, with no intermediate steps.

Each tRNA molecule carries only one specific ____________________, but it can bind with up to three codons.

The first amino acid in most proteins is methionine.

What is the sequence of the codon that the transfer RNA shown in the figure below would bind to during translation?

Use the chart below to determine the chain of amino acids that would be produced by the sequence of this very short, complete gene: UAUUAUGCCUGAGUGAAUUGCUA.

Which of the following does not take place in the nucleus?

Translation occurs in the ____________________ of the cell, where ribosomes are located.

Consider a build-at-home bookshelf that comes with instructions and various pieces of wood as an analogy for translation. In this analogy, what would best match the job of the ribosome?

Each tRNA molecule has a site at one end that

Protein coding genes specify the production of _____ as their immediate product.
