DNA

Deoxyribonucleic acid is the hereditary material in humans and almost all other organisms.

A bar code pattern from DNA unique to each organism

Weak bond between nitrogenous bases in DNA molecule

Openings in nuclear membrane that allow mRNA to leave nucleas.

Name of bond that forms between amino acids in protein molecule

Process by which DNA molecule makes identical copies of itself

Type of sugar found in an RNA molecule

Stage of protein synthesis during which mRNA forms from DNA

Stage of protein synthesis during which tRNA interprets the message on the mRNA to form a specific protein

Type of nucleic acid that carries a specific amino acid

Nitrogenous base found only in RNA molecules

A sugar molecule found in a nucleotide of DNA

Stores an organisms genetic info Controls the production of proteins.

Cell nucleas (nuclear DNA) Mitochondrion (mitochondrial DNA /mtDNA) Chloroplast (Chloroplastic DNA)

Deoxyribose sugar, nitrogenous base, phosphate

Divided into 2 groups which are pyramidines (thymine & cytosine) & purines (adenine & guanine)

Only a pyramidine & purine pairing has width consistent with DNA Purine+purine is too wide Pyramidine+pyramidine is too narrow

Double helix

Refers to the over & under winding of strands. Important for DNA packaging within all cells & reduces the space & allows for much more DNA to be packaged.

When a specific pyramidine base bonds with a specific purine base

It is made up of many nucleotides bonded together

Building blocks/monomers of nucleic acids

RNA has : uracil DNA has: thymine instead RNA has: ribose sugar DNA has: deoxyribose RNA has a single stranded molecule DNA has a double stranded molecule

A very long molecule made up of a string of repeating nucleotides
