Structure of DNA
Consists of 5-carbon deoxyribose sugars and phosphate groups
What is sugar-phosphate backbone?
Nucleobases used to make pairings
What are guanine (G), cytosine (C), adenine (A), and thymine (T)?
Is a double stranded molecule
What is DNA?
Encodes amino acid sequence of a polypeptide
What is mRNA?
Is a double ring purine
What is adenine?
Formed by nitrogenous bases
What are base pairs?
hold pairings together
What are hydrogen bonds?
Is a single stranded molecule
What is RNA?
Brings amino acids to ribosomes during translation
What is tRNA?
Is a purine
What is Guanine?
Occurs where the backbones are close together
What is the minor groove?
Has two hydrogen bonds
What are A (adenine) and T (thymine)?
Has four nitrogen bases adenine, thymine, cytosine, and guanine
What is DNA?
With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA
What is rRNA?
Is a single ring pyrimidines
What is Thymine?
occurs where the backbones are far apart
What is the major groove?
Has 3 hydrogen bonds
What are C (cytosine) and G (guanine)?
Has four nitrogen bases adenine, uracil, cytosine, and guanine
What is RNA?
Small nuclear RNA: With proteins, forms complexes that are used in RNA processing in eukaryotes
What is snRNA?
Is a pyrimidines
What is cytosine?
