nucleic acid Flashcards
what are the functions of nucleic acid?
what characteristics living things have (eg. DNA)
directs protein synthesis within the cell (RNA)
energy carrier within the cell (ATP)
what is the monomer called and what is it made of?
a nucleotide (nt) made up of a phosphate, sugar, and nitrogenous base
what two things can polymer be?
RNA (ribonucleic acid)
DNA (deoxyribonucleic acid)
what is RNA?
single strand of nucleotides (nt)- each nt contains ribose sugar
what is DNA?
double stranded nucleotides (nt)- each nt contains deoxyribose sugar
what components are in DNA?
cytosine
guanine
adenine
thymine
what components are in RNA?
cytosine
guanine
adenine
urasil
what is the difference between DNA and RNA?
DNA has thymine and RNA has urasil
what does ATP consist of?
three phosphate groups, ribose, and adenine
what does adenine and ribose make?
adenosine
who was Rosalind Franklin?
x-ray crystallized DNA and proved DNA is a helical structure
died of stomach cancer (due to radiation)
who took credit for Rosalind Franklin’s work?
Watson and Crick
