X. HUMAN GENETIC ENGINEERING: CLONING
AND RECOMBINANT DNA
"God created humans in His Own image.He created humanity in the image of God...[both]
male and female. God blessed them and God said to them: 'Be fruitful and multiply!'.... None
of you shall approach to any that is near of kin...to uncover their nakedness.... The Lord called
me from the womb. From the bowels of my mother He has mentioned my name.... The Lord
formed me from the womb to be His servant....The Lord...forms the spirit of man within him. -
Genesis 1:27f; Leviticus 18:6; Isaiah 49:1-6; Zechariah 12:1.
3644. Human Genetic Engineering (alias HGE) embraces a variety of life-promoting procedures. All
of them purport to "create" or to "improve" the human race in a pre-conceptional setting. HGE
is not concerned with either post-conceptional or postnatal surgery (such as that involved in
the cutting of umbilical cords, or the separation of humanly-separable Siamese twins, or
appendectomies, or heart transplants). Such surgeries are subsequent to conception - and are
variously either permissible or impermissible in the light of the eternal and comprehensive Law
of God anent existent human persons.1
Human genetic engineering, cloning, and genetic recombination
3645. In HGE, we are concerned solely with pre-conceptional procedures - occurring before the
existence of the person(s) to be most affected. HGE may be either non-conceptional or pro-
conceptional. So we shall here look at pre-conceptional non-conceptional cloning - and also at
the different pre-conceptional and pro-conceptional genetic recombinations - as distinct from
post-conceptional embryonic improvements etc.
3646. We shall not discuss CES (alias Corrective Embryonic Surgery) - till paragraphs 3799f at the
end of this chapter. For CES - although some-times miscalled 'genetic engineering' - is
essentially different. Indeed, CES does not alter the genes or the pro-conceptional cells in
organic matter prior to conception in the way both cloning and DNA recombinations do.

Now by (non-conceptional) "cloning" is meant the non-spermatic and non-sexual duplication of
artificial specimens genetically and sexually identical to the original specimen. 1952 saw the first
successful cloning of frogs, from tadpole cells. Professor Dr. J.B. Gurdon, using the Briggs-King
technique,2 this by transplanting the nucleus of an intestinal cell from a tadpole (A) cloned a colony of
identical South African claw-frogs. He did into the denucleated egg-cell of another frog of similar
species (B). Very amazingly, the thus-stimulated egg-cell divided, and kept on dividing into a
blastocystic cluster of several cells (which we here call C & D & E & F etc.).
3648. Gurdon then divided those cells from one another, and impregnated each one of them (C & D
& E & F etc.) into one of a similar number of denucleated egg-cells (0 & P & Q & R etc.). Each
of the latter was similar to the original denucleated egg-cell B. Once cells C & D & E & F (etc.)
had impregnated the denucleated egg-cells O & P & Q & R (etc.), the latter then developed
into a whole colony (S & T & U & V & W & X & Y & Z etc.) of tadpoles (which in turn later
became frogs).
3649. Those several tadpoles (S & T & U & V & W & X & Y & Z etc.) were all identical both to one
another and also to the first tadpole A from which the original cell had been taken. In this way,
tadpole A had now been cloned into the "identical octuplets" (S & T & U & V & W & X & Y & Z
etc.). Each of them was also an "identical twin" of its own "identical parent" A. So, A - through
human agency - had been induced artificially to (re)produce (S & T & U & V & W & X & Y & Z
