GENETICS AND DNA

Genetics 1

100

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

1

200

Heterozygous means?

The two alleles are DIFFERENT.

300

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

Gregor Mendel

400

This is a number that describes how likely it is that an event will occur.

Probability

500

This is the passing of physical characteristics from parent to offspring.

Heredity

Genetics 2

100

This is the study of heredity

genetics

200

This model shows all of the possible outcomes of two parents sharing genes.

Punnett square

300

There are different forms of a gene.

alleles

400

This type of organism has 2 dominant alleles for a trait.

Homozygous dominant

500

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

Plants / pea plants

Genetics 3

100

This is an organism's physical appearance.

Phenotype

200

If a rabbit with a homozygous dominate color breeds with a heterozygous rabbit, what genotype would the offspring show? (make a punnett square)

heterozygous

300

This model shows traits passed along from generation to generation

Pedigree

400

A white flower and red flower are crossed, and the offspring are pink. What is this called?

Co-dominance

500

If a shape is colored in on a pedigree it means what?

That a specific trait is present/there.

DNA 1

100

The full word for DNA is what?

Deoxyribonucleic Acid

200

Our DNA stores what?

The genetic material that makes up all of us.

300

What is the shape of DNA?

Double helix, Twisted ladder, Twisted zipper

400

How many nucleotides are there in TOTAL?

5, Adenine (A), Cytosine (C), Thymine (T), Guanine (G), Uracil (U)

500

What is one difference between DNA and RNA?

RNA is single stranded instead of DNA.

It contains Uracil (U) not Thymine (T).

RNA has a sugar ribose instead of a deoxyribose.

DNA 2

100

Factors that control traits are called.....

Genes

200

Which nitrogens base connect to each other in DNA?

(A) connects to (T). (C) connects to (G).

300

The process of making a protein from RNA is called?

Translation

400

What happens when there is a change in the nucleotide sequence of a gene

Mutations

500

What are the three kinds of mutations?

Substitution, Insertion and Deletion

RANDOM SCIENCE TRIVIA

What is the most common element in the human body?

Oxygen

200

What type of matter has a definite volume but NO definite shape?

Liquid

300

Which planet has the most moons?

Saturn

400

What is the HARDEST naturally occurring substance on Earth

Diamond

500

What is the fasted moving sea creature?

Sailfish (I will allow sword fish since they're related)
