DNA BASICS
This molecule stores genetic information in living things.
What is DNA?
These four letters represent the bases found in DNA.
What are G, C, A, and T?
This is the basic building block of DNA.
What is a nucleotide?
This structure is made of tightly coiled DNA.
What is a chromosome?
This part of the cell contains most of the DNA.
What is the nucleus?
This base always pairs with Adenine (A).
What is Thymine (T)?
Many nucleotides linked together form this molecule.
What is DNA?
Genes help determine these characteristics in organisms.
What are traits?
DNA is shaped like this twisted structure.
What is a double helix?
This base pairs with Cytosine (C).
What is Guanine (G)?
A nucleotide is made of these three parts.
What are a sugar, phosphate, and nitrogen base?
Genes are best described as these.
What are sections of DNA with instructions?
DNA belongs to this group of biological molecules.
What is a nucleic acid?
This rule explains why A pairs with T and C pairs with G.
What is base pairing?
This part of the nucleotide helps form the backbone of DNA.
What is the sugar‑phosphate group?
How many pairs of chromosomes do Humans have.
What are 23 pairs.
DNA provides instructions for making these important molecules.
What are proteins?
If one DNA strand has the bases A–G–C, the matching strand would be this.
What is T–C–G?
This part of the nucleotide determines whether it is A, T, C, or G.
What is the nitrogen base?
This is a different form of a gene.
What is an allele.
