PROTEIN SYNTHESIS Flashcards
through this, the “working copies” of DNA is expressed through transcription and then further translated
RNA
does not contain equal amounts of specific bases and molecules
RNA
types of RNA
hnRNA
snRNA
mRNA
rRNA
tRNA
hnRNA
HETEROGENOUS NUCLEAR RNA
snRNA
SMALL NUCLEAR RNA
mRNA
MESSENGER RNA
rRNA
RIBOSOMAL RNA
tRNA
TRANSFER RNA
type of RNA that directly by DNA transcription
hnRNA
type of RNA wherein post-transcription processing converts heterogenous nuclear RNA to messenger RNA
hnRNA
type of RNA that facilitates the conversion of heterogenous nuclear RNA to messenger RNA
snRNA
type of RNA that contains from 100 - 200 nucleotides
snRNA
type of RNA that carries genetic information to the site for protein synthesis
mRNA
type of RNA that combines with specific proteins to form ribosomes
mRNA
type of RNA that has the most abundant type of RNA in a cell
rRNA
percentage of rRNA in a cell
75% - 80%
type of RNA that delivers amino acids to the sites for protein synthesis
tRNA
type of RNA that are smallest of the RNAs and possess only 75-90 nucleotide units
tRNA
process by which DNA directs synthesis of hnRNA or mRNA molecules that carry code information needed for protein synthesis
TRANSCRIPTION
short segment of DNA strand that contains instructions for formation of specific hnRNA/mRNA
GENE
segment of a DNA strand that contains the base sequence for production of specific hnRNA/mRNA
GENE
genes are composed of how many units of nucleotide
1000-3500
