Answer:

Australia has so many genetically distinct organisms because it has been separated from other bodies of land for a very long time. This has given species in Australia a long time to evolve independently from species in other areas of the world.

What role does the MutL protein play in DNA repair? (5 POINTS) It performs a proofreading function, similar to DNA polymerase, a
Zinaida [17]

Answer:

It recognizes and binds to a pair of "mismatched" nucleotides, preventing their translation.

Explanation:

Mut L protein is involved in mismatch DNA repair. MutL protein is complexed with MutS protein and the MutL-MutS complex recognizes all the mismatched base pairs present in the newly formed DNA strand. The complex can not recognize the "C-C" pairs. MutH protein joins the complex.

The MutH protein also has a site-specific endonuclease activity and cleaves the unmethylated DNA strand towards the 5' end of the guanine base in the GATC sequence to mark the strand for DNA repair. In this way, MutL protein, along with MutS and MutH proteins mark the mismatched DNA bases for repair so that they are not translated into a faulty protein.

In a soft-bottomed intertidal community, oxygen would be most plentiful for meiofauna in which type of bottom?
Sonbull [250]

Answer:

The options are:

A. Gravel

B. Sand

C. Silt

D. Clay

E. Mud

The answer is A. Gravel

Explanation:

Meiofauna are small benthic invertebrates which live in aquatic habitat. They are suited for both marine and fresh water environments.

Gravel aren’t tightly packed together in large quantities when compared with the other options such as sand, silt, clay, mud. This makes it possible for more aeration and the presence of more oxygen at the soft-bottomed intertidal community.
