what are proteins createdd on
ribosomes
what processes form proteins
transcription translocation
why is a copy of the gene crreatedd by mRNA
so it can be crarried ffrom the nucleus–> cytoplasm
what does DNA helicase do to the gene in transcription
breaaks the hydrogen bonds between the basee pairs
what is attracted to the exposed complimentary bases on DNA
freee RNA nucelotides
what is the relationship between the free RNA nucleotidees and and the bases
it is attracted to it by complimentary base pairing
what catalysese the reaction between the RNA nucleotides
RNA polymerase
what is the role of then enzyme RNA polymerase
catalyses the adjacent RNA nucleotides together
what does pre mRNA consist of
introns extrons
why do we not need the introns?
they dont code for amino acids
how do we remove the introns
splicing
what is splicing
the removal of introns in pre-mRNA
during the first stage of translocation what does the mRNA bind onto
ribosome
what is the anticodon on tRNA
has 3 bases that can bind onto mRNA
what does the tRNA do to the start codon
complimentary anticodon binds onto it.
explain the strucue of tRNA
has an anticodon and an attachment of an amino acid
what happens when the ribosome moves along the mRNA
anotherr tRNA binds onto the codons va its anticodons
what bond occurs between 2 tRNAs and their amino acids
peptide bond
