describe what gene expression involves
the translation and transcription of DNA sequences
describe RNA
single stranded and is composed of RNA nucleotides
what are RNA nucleotides composed off
phosphate group, ribose sugar, and a nitrogenous base
what are the four nitrogenous bases
uracil, adenine, guanine, cytosine
name the three types of RNA
mRNA, tRNA, rRNA
describe the function of mRNA
mRNA carries a complementary copy of the DNA code from the nucleus to the ribosome
describe the transcription of mRNA
mRNA is transcribed from DNA in the nucleus and translated into proteins in the cytoplasm
describe a codon
a triplet of bases on mRNA that codes for a specific amino acid
what are the three exposed bases known as on tRNA
an anticodon
what is the end of a tRNA molecule called
amino acid attachment site
what does the tRNA molecule carry
carries its specific amino acid to the ribosome
what is the ribosome composed off
ribosomal RNA and form the ribosome
