Unit 1 - KA1 - DNA Structure Flashcards
What is the repeating unit of DNA composed of a deoxyribose joined to a phosphate group and a base.
Nucelotide
The term for the deoxyribose and phosphate of each nucleotide are joined together in a long permanent chain with the base pointing inward.
Sugar-phosphate backbone
What is the sugar group present in DNA.
Deoxyribose
What type of bond forms between complementary bases on the parallel strands of DNA.
Hydrogen bonds
The term for two strands of DNA running in opposite directions.
Anti-parallel
The term for adenine pairing with thymine and guanine pairing with cytosine
Complementary base pairing
General name for the 4 nitrogenous organic molecules which determine the DNA sequence.
Bases
What is determined by the sequence of bases.
Genotype
Order of amino acids and types of protein produced
The 3’ strand of DNA ends with this.
Deoxyribose sugar
The 5’ strand of DNA ends with this.
Phosphate
What are found in mitochondria and chloroplasts.
Circular chromosomes
These cells have a membrane bound nucleus.
Eukaryotes
These cells do not have a membrane bound nucleus and may contain small rings of DNA.
Prokaryotes
Small rings of DNA that may be found in bacterial cells and yeast cells).
Plasmid
DNA found in the nucleus of eukaryotes is found in these.
Linear chromosomes
