Pahoehoe. Pahoehoe is the second most abundant type of lava flow. Pahoehoe lava is characterized by a smooth, billowy, or ropy surface. Pahoehoe flows tend to be relatively thin, from a few inches to a few feet thick.In map-view the flows tend to be narrow and elongate.ther types of lavas include block lava, which has a surface of large angular blocks, and rhyolite lava. These two types are associated with lava chemistries other than basalt.
The major component of the bacterial genome is one double-stranded, circular DNA molecule.. Source: Biology, Sixth Edition Campbell and Reece.eptidoglycan is a polymer of interlocking chains called monomers. The b â¦ ackbone molecule is composed of two glucose derivatives (amino sugars) abbreviated NAM and NAG which are connected by interpeptide bridges.
Genome. DNA is the language of life. Just like you, bacteria have DNA that stores genetic information. The basic Watson and Crick structure of DNA is identical in you, your dog, and the bacteria living on and inside of you and your dog.But the genome of an organism is much more than just the DNA bases.Once we really dig into the bacterial genome, we can see some major differences between the genomes of you and your dog and a bacterial genome. A genome is the complete set of genes in an organism.ut the genome of an organism is much more than just the DNA bases.
