100

The term used to describe the shape of DNA. 

What is a double helix?

100

A sequence of RNA based on a sequence of DNA made in the nucleus of a cell; it is also single stranded. 

What is messenger RNA (mRNA)?

100

This is where DNA replication (making a copy of DNA) takes place.

What is the nucleus?

100
With RNA, A (adenine) binds with this other base.
What is U (uracil)?
200

The sugars and the phosphates.

What is the "backbone of a DNA molecule"?

200

This type of RNA carries an amino acid; it also has another region that has an anticodon.

What is transfer RNA (tRNA)?

200
This is where transcription takes place.
What is the nucleus?
200

This mRNA codon is made from the following DNA sequence: TAC

What is "AUG"?

300
A (nitrogenous) base, a sugar, and a phosphate.
What are the 3 parts of a nucleotide?
300

A 3-base sequence of mRNA.

What is a codon?

300
This is where translation takes place.
What is the cytoplasm?
300

This amino acid pairs with the codon "AUG". (Use the codon chart)

What is "met"? 

400

The four bases found on DNA. 

What is A, T, C and G?

400
A 3-base sequence found on tRNA.
What is an anticodon?
400
This is what holds the mRNA strand in place while translation proceeds.
What is the ribosome?
400

The type of mutation occurs when "stop" is made instead of a regular amino acid. 

What is a nonsense mutation? 

500

The type of bond that holds bases together in the double helix.

What is a hydrogen bond?

500

This base is NOT found on RNA. 

What is thymine? 

500
When mRNA is transcribed from DNA, it then slips through these to get into the cytoplasm.
What are the nuclear pores?
500
Most of the amino acids of a protein are incorrect due to this type of mutation.
What is a frameshift mutation?
