Key Vocabulary Terms Related to DNA and Genes
To review vocabulary answers effectively, it’s useful to focus on the most essential terms.
Here’s a breakdown of some critical vocabulary you’ll encounter when studying DNA and
genes:
1. DNA (Deoxyribonucleic Acid)
DNA is the hereditary material found in nearly all living organisms. It stores the
instructions needed to build and maintain those organisms. DNA’s structure is famously
described as a double helix, composed of nucleotide bases: adenine (A), thymine (T),
cytosine (C), and guanine (G).
2. Genes
Genes are specific sequences of DNA that code for proteins or functional RNA molecules.
Each gene serves as a blueprint for making a particular protein, which performs a specific
function in the body.
3. Chromosomes
Chromosomes are tightly packed structures of DNA and proteins found in the nucleus of
cells. Humans typically have 23 pairs of chromosomes, which carry thousands of genes.
4. Nucleotide
A nucleotide is the basic building block of DNA and RNA. It consists of a sugar molecule, a
phosphate group, and a nitrogenous base (A, T, C, or G in DNA).
5. Transcription and Translation
These processes describe how genetic information is converted into proteins.
Transcription is when DNA is copied into messenger RNA (mRNA), and translation follows
as mRNA is decoded to build proteins.
6. Mutation
Mutations are changes in the DNA sequence that can affect gene function. Some
mutations are harmless, while others can lead to diseases or genetic disorders.
7. Allele
An allele is a variant form of a gene. Different alleles can result in variations in traits, such
as eye color or blood type.
8. Genotype and Phenotype
Genotype refers to the genetic makeup of an organism, while phenotype is the observable
physical or biochemical characteristics influenced by the genotype.
