what combines at the start of transcription
mRNA
which RNA does ribosome read
termination signal
what marks the end of a gene
tRNA
where are anticodons located
ribosomal RNA
What does rRNA stand for?
translocation
what mutation is when chromosomes segments are moved from one area to another area
anticodon and amino acid
what does tRNA bring
UGU and UGC
what are the codons for amino acid cystine
messenger RNA
What does mRNA stand for?
inversion
what mutation happens when the segment is copied backwards
no
is every mutation harmful
UGG
what is the anticodon for ACC
termination signal
what marks the end of a gene (end of transcription)
genetic variation
what is a mutation that happens and changes the appearance of a species over time
insertion
what mutation happens when extra bases are inserted
cancer
what is the form of mutation where the genes that control how a cell divides is affected
stop codon
what is the name of the codon that does not have an anticodon
yes
when the ribosome gets done translating mRNA can it be used again on the same strand of mRNA
3
how many nucleotides are read at one time during translation
polypeptide chain
what is a chain of amino acids that are linked with peptide bonds called
mRNA, tRNA, rRNA
what are the different types of RNA
leave the nucleus
at the end of transcription what does RNA have to do
peptide bonds
what holds the amino acids together
ribosomes
once the mRNA enters the cytoplasm, what organelle is it looking for
deletion
what mutation happens when part of the DNA strand is not copied (or missing)
Translation
what is the process where RNA is used to create protein
transcription
what is the process called where DNA is used for a template to make RNA
stop codon
what marks the end of translation
5' to 3'

mutation
what is any change in the nucleotide sequence of a DNA molecule called
transfer RNA
what does tRNA stand for
it unwinds, stretches it
what happens to dna when rna polymerase and promoter combine
