Which of the following is part of a clade believed to have died out, leaving no descendants?
galina1969 [7]

Answer:

Paranthropus robustus

Explanation:

2.5 million years ago some autralopithecines were identified by dating fossils from South Africa, meaning they lived a good period of time. Of these, Australopithecus africanus is well known and is a little closer to our species. Other fossils found in excavations in both southern Africa and eastern Africa have been found to be of more recent specimens 2.5 to 2 million years ago. These specimens were classified as Paranthropus robustus and Paranthropus boisei. These australopithecine species became extinct and left no current descendants.

If you block histone deacetylase, what effect would you expect to see on transcriptional activity?.
Shalnov [3]
Histone deacetylase is responsible for removing the acetyl group from the histone 3 lysine 9 residue. Remember that deacetylation is one step in converting euchromatin to heterochromatin. Because euchromatin is transcriptionally active (transcriptional machinery is able to reach gene of interest), and blocking histone deacetylase activity would result in an the DNA remaining as euchromatin, we would expect to see an increase in transcriptional activity.

So there’s your answer: An increase in transcriptional activity.
