The crispr system involves the cas9 enzyme, which identifies specific nucleotides to be cut using a(n) ________ molecule as a gu

bonufazy [111]

Answer:

RNA

Explanation:

CRISPR system was discovered by a Japanese scientist. Naturally bacteria and many other prokaryotes have CRISPR system in their genome which they use as a self defense against a pathogen which is invading them. It consists of inter spaced, short palindromic nucleotide repeats which encode a guide RNA (gRNA). This guide RNA (gRNA) recognizes the target sequence on the pathogen. The gRNA is followed by Cas9 enzyme which along with the gRNA plays a very important role in breaking genome of the pathogen. Once the target gene is cut down the rest of the DNA can be rejoined by non homologous end joining.

But nowadays, scientists are using this system for genome editing and incorporating desired gene between the two ends which are cut down by CRISPR Cas9 system.

Use the drop-down menus to decide if an example of similar traits is likely a homologous structure or an analogous structure.

snow_tiger [21]

Answer:

- Bird wings and dragonfly wings are both used for flight: Analogous structure

- Clams and snails both have similar muscle structure even though the muscles do different jobs: Homologous structure

- Human and giraffe necks both have 7 vertebrae because we are related: Homologous structure

- The flaps of a Venus flytrap have a similar makeup to oak leaves: Homologous structure

Explanation:

Analogous structures are similar structures that have the same or similar functions in unrelated organisms. Analogous structures aren't the result of evolutionary relationships among organisms (i.e., they were not inherited from a common ancestor). On the other hand, homologous structures are structures inherited from a common ancestor. Homologous structures may or may not have an identical function, but they are the result of evolutionary relationships among organisms and, therefore, they are genetically related.

Vadim26 [7]

Answer:

In the traditional phylogeny platyhelminthes is depicted as a lophotrochozoan phylum. What probably led to this change?

The removal of the acoel flatworms (Acoela) from the Platyhelminthes allowed the remaining flatworms to be clearly tied to the Lophotrochozoa.
