DNA general Flashcards
DNA definition
Deoxyribose Nucleic Acid carries genetic information double stranded
RNA definition
Ribonucleic acid carries and decodes the genetic information from DNA. Single stranded
nucleic acids
RNA and DNA
nucleotide structure
made of phosphate and deoxyribose/ribose sugar and nitrogenous base
All of the different bases
Cytosine, adenosine, thymine, guanine
complementary base pairings
Adenine > Thymine
Cytosine > Guanine
Importance of complementary base pairing
The structure of DNA remains exact and orderly, hydrogen bonding between the strands ensures that the DNA molecule does not form an irregular shape. Base pairing enables the strands to seperate so the information can be used in replication and transcription
antiparallel nature of DNA
DNA strands run in opposite directions, and go from 5’ to 3’ direction. The phosphate end will always be the 5’ end (think pha) and the 3’ end will be the sugar
RNA differences
uracil instead of thymine, ribose sugar, single stranded
