mRNA to Go
Lost in Translation
100

If an organism has two of the same alleles, it is called this.

What is homozygous?

100

In traits that are X-linked, males have this number of alleles. 

What is one?

100

This is the enzyme that unzips DNA during replication.

Helicase
100

Location of transcription

What is the nucleus?

100

Location of Translation

What is the cytosol? (Or Rough ER)

200

The physical appearance of an organism is called this.

What is a phenotype?

200

A person with type AB blood is an example of this inheritance pattern.

What is codominance?

200

In PCR, this unwinds the strands of DNA. 

What is heat?

200

In RNA, this base replaces Thymine and pairs with Adenine.

What is Uracil?

200

This molecule brings amino acids to the ribosome.

What is tRNA?

300

This type of cross is used to determine an unknown Dominant phenotype.

What is a test cross?

300

One gene affecting multiple traits is an example of this.

What is pleiotropy?

300

The direction DNA is synthesized.

What is 5' to 3'?

300

This enzyme builds mRNA from a DNA template.

What is RNA Polymerase?


300

This three-base sequence on mRNA codes for an amino acid.

What is a codon?

400

In a dihybrid cross, this is the expected ratio of offspring in the F2 generation.

What is 9:3:3:1?

400

One gene affecting the expression of another gene is this. 

What is epistasis?

400

These short DNA fragments are synthesized on the lagging strand during DNA replication.

What are Okazaki fragments?

400

The region where transcription begins

What is a promoter region?

400

This is what a tRNA is called when it is bound to its amino acid.

What is charged?

500

Mendel’s Law that explains how alleles separate into different gametes.

What is the Law of Segregation

500

The farther apart two genes are on a chromosome, the more likely this event is to occur between them during meiosis.

What is Crossing Over or Recombination?

500

This "rule" determined that the amount of A = T and the amount of C = G in a DNA molecule.

What is Chargaff's rule?

500

Before mRNA leaves the nucleus, it gets a cap, a tail, and these removed.

What are introns?

500

The first codon in most mRNA strands, AUG, codes for this amino acid.

What is Methionine?
