The RNA recognition motif (RRM), also called the RNP motif and the RNA-binding domain (RBD), is the most common RNA-binding domain in hnRNP proteins. Choose important characteristics of RBD

a. RRM domain consists of a four-stranded b sheet flanked on one side by two a helices.

b. To interact with the negatively charged RNA phosphates, the b sheet forms a positively charged surface

c. The 45-residue KH motif is also found in the hnRNP and several other RNA-binding proteins

In pre-industrial period in England, most peppered moths had light coloration. During industrial revolution, many lichens died out and trees became blackened by soot from factories and interestingly, dark colored moths were predominantly seen.

#Question id: 3355

#Unit 11. Evolution and Behavior

Speciation in ancestor as following way

A- Non-swimming populations separated by a river may gradually diverge because there is no gene flow between them

B- Plants commonly exhibit polyploidy, meaning they contain three or more sets of chromosomes

C- The tendency for two species to diverge in morphology and thus resource use because of competition

Which of the following above condition allowed to which type of speciation?
