When cells do not
respond to the signals that normally regulate cell division, cancer results. Cancer cells altered cell division in the
presence of signals that normally inhibit cell growth, with this; they no
longer require special signals to induce cell growth and division. The consequence
of the abnormalities of these cells could lead to mutations in protein-encoding
genes that regulate cell division.
<span>Moreover, they
also inhibit the growth of nearby cells that allow the cancer cells to spread
and invade other tissues. The uncontrollable division form masses of cells
called tumors that can impaired nearby tissues. If these cells stay in their
original site, they are considered benign, if they become invasive, they are
considered malignant which means that cancer cells metastasize, sending tumor
cells to distant locations in the body where new tumors may form.</span>
The question is incomplete. The complete question is:
A recent study compared the Homo sapiensgenome with that of Neanderthals. The results of the study indicated that there was a mixing of the two genomes at some period in evolutionary history. What data were discovered that suggested this conclusion
A) some Neanderthal sequences not found in living humans
B) a few modern H. sapiens with some Neanderthal sequences
C) duplications of several Neanderthal genes on a Neanderthal chromosome
D) some Neanderthal chromosomes that are shorter than their counterparts in living humans
Answer:
B) a few modern H. sapiens with some Neanderthal sequences
Explanation:
The mixing of genomes of two species generally results in shared sequences and some common genetic traits in the descendants of these species. Mixing of genomes of <em>Homo sapiens</em> and Neanderthals would have resulted in the presence of some common gene sequences in their genomes. If the conclusion that the mixing of genomes of these two species has occurred is correct, some of the modern <em>Homo sapiens </em>should have the genome sequences that were otherwise present in the genomes of Neanderthals only but not in that of the <em>Homo sapiens</em>.
