Why do scientists want to sequence the human genome?
When the human genome sequence was finally completed, scientists were surprised to discover that the genome contains far fewer genes than expected. How many genes are present in the human genome? Scientists have also found that there are many more different kinds of proteins in the human cells that there are different genes in the genome. How can this be explained?
The human genome project was an international effort to completely map the all of the genes of humans. The
first information on the human genome generated from this endeavor was published in 2000 and the full
sequence was published in 2003. Since then, estimates of the rumber of genes in the human genome have
steadily declined, and it is now though that there are about 20,500 genes in the human genome, but the
exact number is yet to be determined.
Since we have known the sequence of the human genome for almost two decades, why are scientists still not
sure of the total number of genes contained within the human genome? In other words, why is it taking so
long to determine the number of genes humans have?

- What does it mean to sequence a genome?arrow_forwardA large portion of the human genome is transposons. Collectively, they are most likely: A) an equal mix of DNA and retrotransposons B) mostly DNA transposons because they are found in DNA C) mostly retrotransposons because they copy themselves each time they move D) mostly DNA transposons because they can cut themselves outarrow_forwardA large public and private effort went into sequencing the human genome.

Choose only the best answer. You would still use Sanger sequencing. You would still assemble the sequencing reads into a genome using bioinformatics. You still need to clone the DNA fragments prior to sequencing them. All three of the other statements are true.arrow_forward
