Which is the odd one out?

• A

• T

• G

• P

Answer explanation

The rest are all DNA bases

Which is the odd one out?

• Double helix

• Antiparallel

• Nucleotides

• Cells

Answer explanation

The rest describe DNA structure: antiparallel means the two strands are opposite to each other, DNA is a double helix, DNA is made of nucleotides

Which is the odd one out?

• gene

• DNA base

• chromosomes

• organ

Answer explanation

The rest are found in the nucleus of a cell

Which is the odd one out?

• gene

• DNA base code

• allele

• cell

Answer explanation

The rest can code for a trait

Which is the odd one out?

• A - T

• C - G

• T - A

• A - C

Answer explanation

A cannot bond with C

Which is the odd one out?

• change how a protein is made by altering the genetic code, which might change a trait or cause a genetic disorder.

• A sequence of DNA bases at a specific place on a chromosome that codes for a particular form of a trait.

• a single nucleotide base is replaced, inserted, or deleted

• a change in just one DNA base when its being copied

Answer explanation

The other three are different definitions of a mutation. The odd one out is a definition of alleles

Which is the odd one out?

• heterozygous

• mutation

• homozygous recessive

• homozygous dominant

Answer explanation

The other three describe different allele combinations.

Which is the odd one out?

• a section of DNA that gives the instructions to make a protein.

• a long, coiled structure made of DNA

• controls a specific trait by carrying the code for making a particular protein. recessive

• a segment of DNA found on a chromosome that contains the code for one function or characteristic.

Answer explanation

The other three define a gene, the odd one out defines a chromosome.
