Proteins are made from amino acids. An amino acid has three parts that are joined to a central carbon atom. Identify the three parts that create an amino acid. amino group fatty acid carboxyl group R group C group A chain of 2 carbon atoms and a nitrogen atom is shown. The middle carbon atom is bonded to a hydrogen atom and an R group. The other carbon atom is double-bonded to an oxygen atom and single-bonded to a hydroxyl group. The nitrogen atom is bonded to 2 hydrogen atoms.

Which of the following scenarios is an example of the bottleneck effect? answers a in south africa, much of the afrikaner population is descended from a small number of dutch colonists. in this population, this is an unusually high frequency of pseudoxanthoma elasticum (pxe), an elastic tissue disorder. b four white-tailed deer are introduced to a park in finland. thirty years after their introduction scientists compare the genes in the population and find that there is no variation. c during the industrial revolution, london's air became filled with soot. as a result, birds started eating more of the lighter moths because they were easier to spot than their darker counterparts. over time, the moth population changed so that there were more darker moths than lighter ones. d 10% of the population of american alligators in an area have the recessive trait albinism. a massive flood results in the death of 80% of the population. of the remaining population, 60% have the recessive trait of albinism.

How is transcription similar to translation in terms of base pairing?

When new rock is added to an oceanic ridge, the magnetized strips on either side of the ridge are evidence of sea-floor spreading. this is because the rocks on the two sides of the ridge o are equal in width and in polarity are polar opposites oare magnetized vary in width but are equal in polarity
