100

A wolf with genotype Bb has bushy fur, completely masking the allele for sleek fur (b). Name this pattern of inheritance.

What is Complete Dominance?

100

This double-stranded nucleic acid sequence contains Thymine (T) and is permanently confined inside the eukaryotic cell's nucleus.

What is DNA?

100

The cytoplasmic structure/organelle where mRNA codons are translated into a sequence of amino acids.

What is the Ribosome?

100

In a standard biological pedigree chart, what geometric shape is used to represent males?

What is a Square?

200

Crossing a red-flowered plant (RR) with a white-flowered plant (WW) produces 100% pink-flowered offspring (RW). Name this inheritance pattern.

What is Incomplete Dominance?

200

The cellular process where RNA polymerase reads a gene's DNA strand to create a complementary single-stranded mRNA molecule.

What is Transcription?

200

The number of mRNA nucleotides that form a single codon read at one time by a ribosome.

What is 3?

200

A sample of eukaryotic DNA is analyzed and found to contain 35% Cytosine (C). Calculate the percentage of Adenine (A) present in this DNA sample.

What is 15%?  

300

A black bull (BB) and a white cow (WW) produce a roan calf (BW) that has both distinct black hair AND white hair patchily scattered across its coat.

What is Codominance?

300

If a DNA template triplet reads TAC GGG, what is the transcribed mRNA codon sequence?

What is AUG CCC?

300

If a mutation causes a protein's 3D structural folding shape to change, what happens to the protein's ability to perform its function?

What is it loses, alters, or destroys its biological function?

300

An unshaded male (dominant phenotype F_) and a shaded female (recessive phenotype ff) have a shaded offspring (ff). What MUST be the father's exact genotype?

What is Ff (Heterozygous)?

400

Two speckled butterflies (BW, codominant for Black and White wing spots) mate (BW x BW). What is the expected phenotypic ratio of their offspring?

What is 1 Black: 2 Speckled (Black & White): 1 White?

400

True or False: DNA leaves the nucleus during protein synthesis to travel to the ribosome and directly deliver code to amino acids.

What is False? (DNA remains locked in the nucleus; mRNA carries the transcribed message out to the cytoplasm).

400

Explain why there are 64 possible mRNA codons, but only 20 standard amino acids used to build proteins.

What is redundancy of the genetic code (multiple codons can code for the exact same amino acid)?

400

Two orange alien creatures (RY, which show incomplete dominance between Red R and Yellow Y) mate (RY x RY). What is the genotypic ratio of their offspring?

What is 1 RR: 2 RY: 1 YY (1:2:1)?
