Perhaps God will choose to use modern science and technology, like DNA sequencing or other tools, as one of the means to assist in resurrection, but He certainly does not need to, and has not used them in the past.
In this post, below, I've compiled a few references about Jesus Christ's resurrection, which is the center point of Christianity, including the Mormons, or the Church of Jesus Christ of latter-day Saints. None of these references suggest or hint at them being a parable or analogy as an inspiration for later science. Numerous early Christians were tortured, beaten, then continued preaching this same message--that Jesus came, died, and was resurrected. Those are hardly actions of people defending something that was nothing more than a symbolic myth or parable.
Of course, these references are in the realm of faith, not science, so they are not provable using the scientific method--although we do have plenty of circumstantial and anecdotal evidence. But, I struggle to see how you can believe in the resurrection of Christ 2000 years ago and also subscribe to the transhumanist idea that we will eventually use technology improvements to accomplish the same thing.
Matt. 28:6 (See also Luke 24:6), Mark 16:9
Many other people were also resurrected:
And came out of the graves after his resurrection, and went into the holy city, and appeared unto many.
3 Nephi 23:9
Verily I say unto you, I commanded my servant Samuel, the Lamanite, that he should testify unto this people, that at the day that the Father should glorify his name in me that there were many saints who should arise from the dead, and should appear unto many, and should minister unto them. And he said unto them: Was it not so?
And his disciples answered him and said: Yea, Lord, Samuel did prophesy according to thy words, and they were all fulfilled.
And Jesus said unto them: How be it that ye have not writtenthis thing, that many saints did arise and appear unto many and did minister unto them?
And it came to pass that Jesus commanded that it should bewritten; therefore it was written according as he commanded.
Finally, He promised three of the Nephite apostles they would never die:
