DNA is the complex chemical that carries genetic genetic information.DNA is contained in chromosomes, which are found in the nucleus of most cells
1 of 11
chromosome
A chromosome is a long, stringy aggregate of genes that carries heredity information
2 of 11
gene
a gene is a shorter region of dna that carries the genetic code for a particular characteristic or cell activity
3 of 11
allele
An allele is one of the possible forms of a gene. Most genes have two alleles, a dominant allele and a recessive allele. If an organism is heterozygous for that trait, or possesses one of each allele, then the dominant trait is expressed
4 of 11
Nucleotide
The basic building block of nucleic acids, such as DNA and RNA. It is an organic compound made up of nitrogenous base , a sugar and a phosphate group
5 of 11
base
The bases in the DNA molecule carry the different codes needed for different amino acids
6 of 11
base-pairing
Equal amount of A and T in a DNA sample, as well as equal amounts of G and C
7 of 11
complementary
The bases are paired, and they always pair up the same way always A-T and C-G
8 of 11
Triplet code
The sequence of amino acids in a protein determines its structure and function. The DNA code is a triplet code. Each triplet, a group of three bases, codes for a specific amino acid
9 of 11
sense strand
the segment within double stranded DNA that runs from 5' to 3'
10 of 11
mutation
A mutation occurs when a D
