my nurses,
00:03 - 00:05
What is it and how can it affect you?
00:06 - 00:09
My sister is a process that produces sex sells.
00:09 - 00:12
Otherwise known as gametes and or germ cells.
00:13 - 00:16
This process consists of two different steps,
00:16 - 00:19
which are then broken down into five different stages
00:19 - 00:21
called interphase
00:21 - 00:22
pro fes
00:22 - 00:23
meta phase
00:23 - 00:26
and a phase tele face and psychokinesis.
00:27 - 00:32
All five stages occurred twice. In order for the process of mitosis to be complete,
00:33 - 00:36
the syndrome is considered as a disease and
00:36 - 00:39
or disorder that has more than one identifying issue
00:40 - 00:41
or feature.
00:43 - 00:47
Down syndrome is caused by random error during the cell division.
00:47 - 00:50
It is also referred to as non disjunction, all
00:50 - 00:54
meaning failure to separate during the process,
00:54 - 00:56
typically in the NFA stage
00:57 - 00:58
of my ASUs phone
00:59 - 01:03
and or when sister committed separate in an office two of my access to
01:08 - 01:11
in my ASUs one. During the interface stage,
01:12 - 01:14
the cells begin to prepare for my ASUs.
01:15 - 01:19
Do you know replication occurs, condensing all the chromosomes.
01:19 - 01:24
The chromosomes are then doubled and stuck back together by the central me.
01:25 - 01:27
These are called Sister committed
01:29 - 01:31
now onto pro phase one,
01:31 - 01:33
the longest face
01:34 - 01:41
in pro phase. One homologous pairs are formed and crossing over takes place
01:42 - 01:46
where they exchange segments of DNA and become Newell eels.
01:47 - 01:49
These are called synopsis
01:50 - 01:56
here, the central the central's moved to their assigned polls.
01:57 - 02:00
The duplicated chromosomes are no longer identical,
02:00 - 02:03
causing a variation in the final gametes,
02:04 - 02:07
the spindle fibres then attached to the chromosomes and
02:07 - 02:11
shift towards the centre during the meta phase stage.
02:13 - 02:15
This is uncontrolled and random,
02:15 - 02:18
meaning that you will not know which way they will face.
02:19 - 02:24
This then leads to the homologous chromosomes to separate.
02:25 - 02:27
Then we start the beginning of a new FAS
02:27 - 02:28
and FAS one.
02:29 - 02:31
During the stage,
02:32 - 02:34
the spindle fibres pull apart
02:35 - 02:41
the pair of each poll of the cell as the micro tubules are being shortened.
02:42 - 02:45
But what does this have to do with Down syndrome?
02:46 - 02:46
Well
02:47 - 02:49
down syndrome is when an individual has an
02:49 - 02:53
extra chromosome and this happens during the N.
02:53 - 02:54
F. A stage
02:55 - 03:00
with the chromosome does not separate and joins with the other two chromosomes
03:02 - 03:04
coming back to tell a face. One
03:05 - 03:06
tell a phase one
03:06 - 03:08
is when two intermediate
03:08 - 03:10
cells are formed
03:10 - 03:18
containing the nuclei which reform and the chromosomes form into Crimea. Teens
03:20 - 03:24
during the psychokinesis face the remainder of
03:24 - 03:27
the cytoplasm divides into two whole cells.
03:30 - 03:30
Mhm
03:31 - 03:36
down syndrome is likely to occur in my house is too in an office to
03:36 - 03:40
the same process occurs in an office to like in an office one.
