Nucleic acid Flashcards
what is DNA?
deoxyribonucleic acid amd it stores genetic info
What is RNA?
ribonucleic acid which transfersgenetic info from the DNA to the ribosomes
what is the basic structure of all Nucleotides?
one phosphate group, pentose sugar, nitrogenous base
what is DNA in pentose sugar?
pentose sugar in DNA is deoxyribose.
what is the pentose sugar in RNA called?
Ribose
what are the four nitrogenous bases in DNA and RNA?
Cystonine, guanine, aderine.
what does DNA also contain?
Thymine
what does RNA also contain?
Urcail
what is the difference between the structure of RNA and DNA?
RNA forms a single helix whereas DNA forms a double helix.
how are the nucleotides in these helices held togethere?
by phosphodiester bonds
how ia the structure of DNA?
its antiparallel - the strands run in opposite directions
how is DNA double helix?
due to hydrogen bonds between complementary base pairs.
what does adenine pair with?
thymine
what does cystonine pair with?
Guanine
