In comparison to a DNA strand, a

mRNA strand is shorter and single stranded

mRNA strand is longer and single stranded

mRNA strand is shorter and double stranded

mRNA strand is longer and double stranded

The bonds that hold the two strands of DNA together come from...

weak hydrogen bonds between the bases

the attraction of phosphate groups

strong bonds between bases and sugars

carbon to carbon bonds in the sugar

Which of these is correct?

DNA --> mRNA --> polypeptide chain

DNA --> polypeptide chain --> mRNA

mRNA --> DNA --> polypeptide chain

polypeptide chain --> DNA --> mRNA

Translation is crucial to the process of making proteins. Which statement best describes what takes place during translation?

Information in mRNA is converted into a sequence of amino acids in a protein

A copy of chromosomal DNA is created

A RNA copy of a DNA strand is made.

Instructions from DNA in the nucleus are brought to the cytoplasm

What would happen if we did not have start codons?

Protein synthesis wouldn't occur

Polypeptide chains would continue to grow

mRNA would form a double strand

Which of the following correctly describes enzyme structure and function?

The shape of an enzyme is responsible for its function.

All enzymes can bind to all substrates.

The substrate is responsible for the shape of the enzyme.

The location of an enzyme determines its function.

Which of the following correctly describes how an enzymes shape is determined?

A DNA sequence is transcribed and translated to produce an amino acid sequence that makes up an enzyme and gives it a particular shape.

Enzyme function is determined by the temperature.

Carbohydrate chains are used to produce enzymes and determine their function.

Enzyme shape is determined by the location of the enzyme in the body.

What are the three types of mutation?

Insertion, Deletion, Subsitution

Deletion, Newstion, Subsitution

Insertion, Newstion, Substitution

Why is the order of amino acids so important?

The order of amino acids dictates what shape the protein will fold into.

It is not important. The protein folding chamber will force the protein to fold into the correct shape.

Why are insertion and deletion mutations so harmful?

They change all of the codons from the mutation on down the line, which changes the amino acid sequence

They insert things that an organism doesn't need.

They often delete things that organisms need.

Insertion and deletions are not any more harmful than substitution mutations.

In a point mutation, this would have the worst effect on the function of the protein

an insertion or deletion at the beginning of the gene

an insertion or deletion near the end of a gene

an insertion at the middle of the gene

When an adopted person is more similar to his/her adoptive parents then _________ are more important for a trait, but if that person is more similar to his/her biological parents, then _________ may influence the trait

environmental factors; genetic factors

genetic factors; environmental factors

environmental factors; environmental factors
