    lactose-free
  • 00:00:05
    this is a comment tag which has
  • 00:00:08
    foundered many food packets these days
  • 00:00:10
    lactose as we know is a natural sugar
  • 00:00:13
    found in milk but why should we get rid
  • 00:00:16
    of lactose that's because many people
  • 00:00:19
    have a peculiar intolerance towards this
  • 00:00:22
    natural sugar
  • 00:00:23
    however lactose free products but not an
  • 00:00:26
    option until a few years back it's all
  • 00:00:30
    possible now due to the advancements in
  • 00:00:32
    the field of biotechnology that useful
  • 00:00:35
    products like lactose free consumables
  • 00:00:37
    and many more can be produced so what
  • 00:00:41
    exactly is biotechnology well it's
  • 00:00:45
    defined as the utilization of organisms
  • 00:00:48
    or a part of the organism or any
  • 00:00:50
    biological process for the benefit of
  • 00:00:53
    mankind for example we know how bread is
  • 00:00:56
    made the dough is added with the
  • 00:00:59
    organisms like yeast which help in
  • 00:01:01
    releasing certain chemicals the
  • 00:01:03
    reactions ultimately give us the soft
  • 00:01:06
    and fluffy loaf on baking here we've
  • 00:01:09
    used yeast organism to obtain the
  • 00:01:11
    product of our interest
  • 00:01:13
    so do we mean that bread making is a
  • 00:01:16
    part of biotechnology well kind of
  • 00:01:20
    processes like fermentation are
  • 00:01:22
    considered as a part of classical
  • 00:01:24
    biotechnology as they include the
  • 00:01:26
    utilization of organisms thus obtaining
  • 00:01:30
    products for human benefit like food
  • 00:01:33
    items medicines hybrid crops and so on
  • 00:01:36
    are all possible due to biotechnology
  • 00:01:39
    does there are numerous applications of
  • 00:01:42
    biotechnology now let's have a look at a
  • 00:01:45
    few examples to understand how wide the
  • 00:01:48
    field is let's also understand how an
  • 00:01:51
    organism or a part of it or some
  • 00:01:54
    processes can be used to harvest
  • 00:01:56
    important products for mankind
  • 00:01:59
    let's take examples of white production
  • 00:02:03
    hepatitis B vaccine synthesis and Golden
  • 00:02:06
    Rice production let's have a look at
  • 00:02:09
    each individually
  • 00:02:11
    now wine is usually made from the grapes
  • 00:02:14
    how can grapes which are fruits get
  • 00:02:18
    converted to a beverage like wine well
  • 00:02:21
    this is where the micro organism named
  • 00:02:23
    yeast comes into play it feeds on the
  • 00:02:26
    sugars present in the grape juice and
  • 00:02:28
    releases alcohol and carbon dioxide as
  • 00:02:31
    byproducts here a complete organism is
  • 00:02:35
    used for the processing of grape juice
  • 00:02:37
    and to convert it into wine this was the
  • 00:02:42
    first part of the definition the second
  • 00:02:45
    part of the definition states that a
  • 00:02:47
    part of the organism can be used so how
  • 00:02:50
    can that be done for this let's have a
  • 00:02:53
    look at the application of biotechnology
  • 00:02:56
    in the field of medicine well the
  • 00:03:00
    emergence of biotechnology has been
  • 00:03:02
    nothing less than a boon for the medical
  • 00:03:04
    industry everything ranging from
  • 00:03:06
    vaccines to gene therapy has raised the
  • 00:03:09
    standards of healthy living now let's
  • 00:03:13
    take hepatitis B vaccine as an example
  • 00:03:16
    this vaccine has a recombinant version
  • 00:03:20
    previously hepatitis B vaccine was
  • 00:03:23
    developed from the blood of the humans
  • 00:03:24
    who were already suffering from
  • 00:03:26
    hepatitis B but this was very painful
  • 00:03:29
    for the patients as the amount of blood
  • 00:03:31
    required for vaccine production was too
  • 00:03:34
    high so extracting some particular
  • 00:03:37
    amount of blood of the infected person
  • 00:03:39
    was very excruciating and as the vaccine
  • 00:03:43
    was derived directly from the patient's
  • 00:03:45
    body there could be negative reactions
  • 00:03:47
    in the receiving candidate with the
  • 00:03:50
    development of biotechnology newer
  • 00:03:53
    vaccines that are synthetic in nature
  • 00:03:55
    started getting produced on the similar
  • 00:03:58
    lines the commercially available
  • 00:04:00
    hepatitis B vaccine is now being
  • 00:04:03
    synthetically made by utilizing a small
  • 00:04:06
    part of the pathogenic virus it's also
  • 00:04:09
    known as recombinant hepatitis B vaccine
  • 00:04:12
    and studies have shown that getting
  • 00:04:15
    infected with hepatitis B is nearly
  • 00:04:18
    impossible
  • 00:04:19
    if a person is injected with recombinant
  • 00:04:21
    hepatitis B vaccine isn't this a miracle
  • 00:04:26
    it is equivalent this is also known as
  • 00:04:30
    the first anti-cancer vaccine and why so
  • 00:04:34
    because it's proven that the vaccine
  • 00:04:37
    helps in reducing the chances of
  • 00:04:39
    developing liver cancer this is one
  • 00:04:42
    example of how apart from any organism
  • 00:04:44
    can be used for product development
  • 00:04:48
    now that we've glanced at the two
  • 00:04:50
    examples of application of the
  • 00:04:52
    biotechnology let's move ahead to the
  • 00:04:54
    third one the last part of the
  • 00:04:57
    definition stated the use of a process
  • 00:05:00
    let's take the Golden Rice as a third
  • 00:05:03
    example is the rice made of gold
  • 00:05:06
    no absolutely not then why is it called
  • 00:05:10
    Golden Rice well the rice we usually see
  • 00:05:14
    is whitish in color
  • 00:05:15
    however the golden rice we're talking
  • 00:05:18
    about is a modified version which is
  • 00:05:20
    yellowish in color hence the name golden
  • 00:05:23
    rice but what makes this rice yellowish
  • 00:05:27
    and so important it's the presence of
  • 00:05:30
    beta-carotene in the rice and what is
  • 00:05:33
    that beta-carotene is a red orange
  • 00:05:37
    colored pigment which gets converted to
  • 00:05:39
    vitamin A in the human body we all know
  • 00:05:43
    the importance of this vitamin it is
  • 00:05:46
    most essential for the development and
  • 00:05:48
    maintenance of good vision the
  • 00:05:52
    deficiency of vitamin A causes vision
  • 00:05:55
    related issues and malnutrition
  • 00:05:57
    any idea why was only rice chosen for
  • 00:06:01
    modification that was because the staple
  • 00:06:04
    diet for a majority of the population in
  • 00:06:07
    the areas affected with vitamin A
  • 00:06:09
    deficiency was rice so to minimize the
  • 00:06:13
    deficiency this variety of rice was
  • 00:06:16
    developed the modification of rice was
  • 00:06:19
    done by exploiting a biological process
  • 00:06:21
    making it a classic example of
  • 00:06:24
    biotechnological achievements this
  • 00:06:27
    variety of rice falls under the category
  • 00:06:30
    of genetically modified organisms
  • 00:06:32
    abbreviated as GMOs and what exactly are
  • 00:06:37
    these G
