protein synthesis vocabulary Flashcards
How does DNA needed to use proteins from the nucleus to the ribosomes
DNA makes mRNA which leaves through the nucleuar pores in the nucleus. Ribosomes then read the mRNA to make proteins.
messenger rna
Carries info from DNA and delivers it to ribosome.
Ribosomal RNA
Structural component of ribosomes
tRNA
transfer rna
Translates mRNA sequences into amino acid sequences
step one of transcription
binds to DNA and signals to start making RNA, then unwinds/splits DNA into 2 separate strands.
step two of transcription
DNA acts as a template for making mRNA.
step three of transcription(rna polymerase)
moves along the DNA and pairs each base with a complementary RNA nucleotide
step four
until enzyme reaches a terminator (stop signal). RNA Polymerase – detaches from DNA and releases mRNA from the nucleus.
start codon
the spot where the amino acids start to make proteins.
aug is the olny
start codon
UAA, UAG, UGA
three stop codon
RNA is read 3 nitrogen bases at a time
Each triplet of base
codon
