<span>While alien genomes may be constructed by completely different molecules (for example, silicon based life forms are a possibility rather than carbon) it is logical to assume that all life forms would have some sort of protective mechanism to prevent the degradation of DNA during replication. Essentially, to prevent mutations and rapid aging, DNA, alien or otherwise, would have some types of telomeres. They might either be long chains of repeated or irrelevant code or molecules that would not be easily corrupted.</span>
The best answer would be "research reasons why species change over long periods of time"
if not i apologize but this is my best guess<span />
Answer:
<em>e. speciation</em>
Explanation:
The definition of speciation is: the evolutionary process by which populations evolve to become distinct species.
In this scenario, the bears that were once of the same species evolved in order to adapt to their environment. Once they evolved, they could no longer produce with each other, as they are now different species.
Question
Microarrays allow for
•a comparison of expression of different genes under different growth conditions.
• the analysis of global gene expression.
•the hybridization of cDNA (converted from mRNA with DNA affixed to a solid-state support.
• all of the above.
Answer:
• all of the above.
Explanation:
Microarray involves the collection and isolation of genetic samples (DNA) from a sample or tissue.
Microarray is composed of a large number of DNA material that is arrange sequentially for easy identification and use.
Microarray is used to compare the expressions of various types of genes that are growing under different conditions. It can also be used for analysis of genes globally.
I believe the Southern Rocky Mountains such as the San Juan Mountains in Colorado and the La Sal Mountains in Utah.
