Genetics Flashcards

Front

Adenine

Back

One of the nitrogenous bases found in DNA and RNA. Pairs with thymine in DNA and uracil in RNA.

Front

Allele

Back

One of the alternative forms of a gene.

Front

Anticodon

Back

A group of three bases on a tRNA molecule that are complementary to the codon on the mRNA.

Front

Base

Back

A nitrogen-containing group found in the DNA and RNA molecules (A, T, U, C and G).

Front

Chromosome

Back

A threadlike structure in the nucleus formed of DNA.

Front

Codominant

Back

Alleles where both are expressed in the heterozygote.

Front

Codon

Back

Set of three bases on the mRNA molecule.

Front

Cytosine

Back

One of the nitrogenous bases found in DNA and RNA. Pairs with guanine.

Front

DNA

Back

Deoxyribonucleic acid encodes the genetic information of the organism, formed from many nucleotides arranged in a double helix.

Front

DNA replication

Back

Copying of DNA that happens before cell division.
