This was the scientist who first began studying heredity and genetics.
Gregor Mendel
100

This is an organism's genetic makeup. (Example: aa)

Genotype

100

A section of DNA that codes for a particular protein is called

a gene

100

The location where transcription takes place

Nucleus

100
This type of organism has 2 different alleles for a trait
Heterozygous
200

What did Gregor Mendel cross-pollinate in his genetics experiments?

Plants / pea plants

200

This is an organism's physical appearance. (Example: blue eyes)

Phenotype

200

What nucleotide pairs with thymine in DNA?

Adenine

200

The process of copying a segment of DNA into mRNA.

Transcription

200
This type of organism has 2 recessive alleles for a trait
Homozygous recessive
300

What was the main conclusion of Mendel's pea plant study?

Dominant and recessive traits.

300

This shows all of the possible outcomes of a genetic cross.

Punnett square

300

The coiled structures in which DNA is tightly packaged within the nucleus

Chromosome

300

In this process, messenger RNA (mRNA) is decoded to produce a specific amino acid chain (protein)

Translation

300

AA can also be referred to as

Homozygous dominant

400

This is the trait that is overshadowed

Recessive trait

400
How many dominant alleles are needed for a particular trait to show up?
1
400

The process of DNA being transcribed by mRNA and translated into proteins

Protein synthesis

400

Complimentary strand of DNA: ACCGTA

TGGCAT

400

Do the following cross (A = freckles, a = no freckles):

Aa x Aa

What are the percentages of the possible phenotypes?

75% Freckles

25% No Freckles

500

This is the passing of traits or alleles from parent to offspring.

Heredity

500
What happens when a recessive allele is paired up with a dominant allele?
It is hidden / doesn't show up
500

What are the bonds between nitrogen bases in DNA?

Hydrogen bonds

500

Complimentary mRNA Strand: ACAGT

UGUCA

500

Do the following cross where B = blue eyes, b = brown eyes.

Bb x bb

What are the possible genotypes?

Bb, bb
