Flashcards in Lecture 7 Deck (34):
What direct the formation of an organism/
the 4 nucleotides
What specifiy the linear order of amino acids in each protein?
What determine biological functions a cell
properties of proteins
Does DNA control protein synthesis directly/
What is the intermediary?
What is copied into RNA and what is it called when this happens?
a gene, transcription
What is used as a template to direct the synthesis of protein?
RNA in translation
RNA and DNA
What is made of nucleiotides connected by phosphodiester bonds?
RNA and DNA
What is single stranded?
What does RNA have instead of deoxyribonucleotides?
RNA has.... instead of Thymine
What can fold inot compelx 3 dimensional structures allowing some RNAs to have precids structural anc catalytic functions
Ribose has an OH, deoxyribose has an ...
Uracil has a H.... thymine has a
messenger RNAs, code for proteins
ribosomeal RNAs, form the basic structure of the ribosome and catalyze protein syntehsis
transfer RNAs, central to protein synthesis as a daptors btw mRNA and amino acids
small nucleolar RNAs, help to process and chmicall modify rRNAs
microRNAs, regulate gene expression by blocking translation of specific mRNAs and cause their dgradation
small interferenig RNAs, turn off gene expression by direction the degradation of selective mRNAs and the establishment of compact chromatin structures
direct protein synthesis (3-5% of tal celluarl RNA) Coding RNAs
What is many genes final product
WHat does non coding RNa serve as
enzymatic and structural components for many biological processes
the core of ribosome and catalyze protein synthesis
form the core of ribosomes and catalyze proteins synthesis
form adaptors that select and hold amnio acids during protine synthesis
direct the spicing of pre mRNA to form mRNA
small nuclear RNA
regulate eukaryotic gene expression by degrading select m RNA
small interfering RNA
regulate gene expression by blocking translation of sleecive mRNA
multi subutnit complex
bacterial RNA polymerase (RNA pol)
what is holoenzyme
What Does holoenzyme catalyze?
the formation of phosphodiester bonds that link nucleotides
