DNA Flashcards
DNA stands for
DeoxyriboNucleic Acid
A molecule of DNA has…
Two strands or repeating units called nucleotides
The 3 parts of DNA are
Phosphate
Deoxyribos sugar
Base
The 4 types of bases are
Thymine
Adenine
Cytosine
Guanine
The sequence of based is known as
The genetic code
The genetic code is read to….
Produce proteins
Protein molecules are made of
20 available amino acids
A triplet of bases is known as
A codon
The amino acids are linked tightly to make
A protive
Each codon carries the code for
One amino acid
The messenger molecule used to carry DNA from the nucleus to the cytoplasm is
mRNA
When mRNA combines with
Ribosomes when it reaches the cytoplasm
When the code arrives in the ribosomes
The mRNA strand is read in codons and this allows the amino acids to line up in the correct sequence
