word frame shift says it all causing a shift in

00:24

the genetic code either to the left or to the

00:27

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

00:29

this adorable babies blocks to arrive at the correct answer

00:32

All right option a deletion is a type of mutation

00:35

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

00:38

lose the ai from the sample code and see what

00:40

happens Well the code has now been shifted to the

00:42

left making it too short and dramatically altering its message

00:46

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

00:49

for the one that does it So onward and upward

00:53

insertion is a type of mutation in which a piece

00:56

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

01:00

not to get too jurassic park e on you here

01:02

but while using insertion in our example this edition shifts

01:05

the code to the right Makes it too long As

01:08

you can see insertion also causes frame shift So b

01:11

is for bye bye translocation events or the transfer of

01:14

pieces of genetic code from one location to another Very

01:17

simply put think of them like bigger multiple insertions or

01:20

deletions Even little baby can see that trans location events

01:24

totally caused cream shift though the one unlike the others

01:28

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

01:32

code so it may not cause frame shifting Substitution sze

01:36

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

01:39

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

01:42

for another Most mutations actually have no effect on an

01:45

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