AP Biology 1.5 Essential Life Process Information

word frame shift says it all causing a shift in

the genetic code either to the left or to the

right Let's work with the sample of genetic code on

this adorable babies blocks to arrive at the correct answer

All right option a deletion is a type of mutation

in which a section of dna is lost so let's

lose the ai from the sample code and see what

happens Well the code has now been shifted to the

left making it too short and dramatically altering its message

So yeah delish in does cause frame shift We're looking

for the one that does it So onward and upward

insertion is a type of mutation in which a piece

of additional dna is put into a code We'll try

not to get too jurassic park e on you here

but while using insertion in our example this edition shifts

the code to the right Makes it too long As

you can see insertion also causes frame shift So b

is for bye bye translocation events or the transfer of

pieces of genetic code from one location to another Very

simply put think of them like bigger multiple insertions or

deletions Even little baby can see that trans location events

totally caused cream shift though the one unlike the others

option c substitution doesn't add or subtract from the genetic

code so it may not cause frame shifting Substitution sze

aren't likely to change the three nuclear tied code on

message They're just being sneaky and changing out one bass

for another Most mutations actually have no effect on an

organism at all Summer Beneficial some or not And hey 00:01:49.512 --> [endTime] sometimes change is a good thing right
