DNA And RNA Flashcards
Chromosomes
A thread like structure within a cells nucleus that contains DNA that is passed from one generation to the next
Double helix
The twisted ladder of DNA
Nitrogen Bases
Molecules that contain nitrogen and other elements that make up the rungs (middle section) or DNA
Adenine
One of 4 nitrogen bases that make up one of the rungs of DNA abbreviated as= A
Thymine
One of four nitrogen bases that make up one of the rungs of DNA abbreviated as= T
Guanine
One of 4 nitrogen bases that make up one of the rungs of DNA abbreviated as= G
Cytosine
One of 4 nitrogen bases that make up one of the rungs of DNA abbreviated as= C
Gene
A section of a DNA molecule that contains the information to code for one specific protein
DNA replication
The process in which an identical copy of the DNA strand in formed for a new cell.
Amino Acids
Molecules that make up proteins
RNA
The genetic messenger that carries the genetic code from DNA inside the nucleus to the ribosome in cytoplasm
Uracil
The nitrogen base that replaces thymine in RNA= u
Messenger RNA
Type of RNA that carries copies of instructions for assembly of amino acids into proteins from DNA to ribosomes in the cytoplasm
DNA
Delxyribonucleic acid; the genetic material that carries information about an organism that is Carrie for. Parent to off-spring.
