Thank you We sneak And here's your shmoop du jour
- 00:05
brought to you by mutants Creatures who have experienced a
- 00:09
genetic change And we'll have a hard time speaking Which
- 00:12
of the following mutations may not cause a frame shift
- 00:16
and hear potential answers All right in this one the
Full Transcript
- 00:21
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
