Answer:
If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.
Explanation:
The question is incomplete as it does not have the options which are:
a) DNA
b) AGCT
c) PCR
d) SNP
Answer:
PCR (polymerase chain reaction)
Explanation:
The polymerase chain reaction is the technique which replicates and produces multiple copies of the DNA molecule artificially in a short period of time.
The PCR technique employs a variety of enzymes and all the prerequisites which are required in the DNA replication in vivo conditions.
In the given question, if the genome of the mummy has to sequence then after the collection of samples from the bones, the DNA has to replicate through the process of PCR. The samples from the different bone structures can be compared and analysed and a complete genome sequence can be analysed.
Thus, PCR is correct.
