100
The number of parents in sexual reproduction.
What is 2?
200
Which nitrogen base always pairs with A?
What is T?
200
After DNA untwists it must do this before free-floating nucleotide bases fill in the spaces.

How you would describe the offspring of an asexual reproducer.
What is clone or identical to parent?
200
The offspring are never ____ to the parents.
What is never identical?
300
Two scientists credited for discovering the shape of DNA.
Who are Watson and Crick?
300
DNA's directions tell the ribosomes how to make these.
What are proteins?
300
The estimated number of genes in the human genome.
What is 30,000-40,000?
300
In order to adapt to an environment, asexual reproducers must rely on these to happen, in order to change the DNA.
What is mutation?
300
This is the male reproductive cell in flowers.
What is pollen?
400
These two chemicals make up the side/backbone of DNA.
What are sugar and phosphate?
400
This cell organelle makes proteins.
What is ribosome?
400
Sort these in order from largest to smallest: genes, chromosomes, bases, cell, nucleus
cell nucleus chromosomes genes bases
400
Asexual reproducers are slower to ______ because there is very little genetic variation.
What is adapt?
400
This term refers to the differences among members of the same species.
What is genetic variation?
500
1 sugar, 1 phosphate and a nitrogen base make up this part of DNA.
What is a nucleotide?
500
This acts as a messenger and gets the DNA code to the ribosomes.
What is RNA?
500
The complete set of DNA in every cell is called this.
What is the genome?
500
An advantage of asexual reproduction is this.
What is takes less time and energy or usually produces more offspring?
500
An advantage of sexual reproduction.
What is genetic variation in offspring or can adapt faster than asexual reproducers?
