Ex Input:
For Fall 2018, Berkeleys acceptance rate for freshman was 15.1%. Total enrollment was 41,910 - 30,574 undergraduate and 11,336 graduate students - with women accounting for 52.7% of undergraduates and 46.2% of graduate and professional students. Of enrolled freshman, nearly 54% were women and approximately 60% self-identified as persons of color. Enrolled freshman had an average weighted secondary school GPA of 4.45 (unweighted GPA of 3.92) and had an average SAT score of 1435 (average ACT score of 32). The interquartile range for SAT scores was 1340-1530, with 660-750 for reading/writing and 670-750 for math. Berkeleys enrollment of National Merit Scholarship Program was third in the nation until 2002, when participation in the National Merit program was discontinued. For 2016-17, Berkeley ranked fifth in enrollment of recipients of the National Merit Scholarship Program (136 scholars). 33% of admitted students receive federal Pell grants.

Ex Output:
In Fall of 2018 were there more women or men enrolled as freshman?

Like water and carbon, nitrogen is also repeatedly recycled through the biosphere. This process is called the nitrogen cycle. Nitrogen is one of the most common elements in living organisms. It is important for creating both proteins and nucleic acids, like DNA. The air that we breathe is mostly nitrogen gas (N2 ), but, unfortunately, animals and plants cannot use the nitrogen when it is a gas. In fact, plants often die from a lack of nitrogen even through they are surrounded by plenty of nitrogen gas. Nitrogen gas (N2 ) has two nitrogen atoms connected by a very strong triple bond. Most plants and animals cannot use the nitrogen in nitrogen gas because they cannot break that triple bond. In order for plants to make use of nitrogen, it must be transformed into molecules they can use. This can be accomplished several different ways ( Figure 1.1). Lightning: When lightening strikes, nitrogen gas is transformed into nitrate (NO3 ) that plants can use. Nitrogen fixation: Special nitrogen-fixing bacteria can also transform nitrogen gas into useful forms. These bacteria live in the roots of plants in the pea family. They turn the nitrogen gas into ammonium (NH4 + ) (a process called ammonification). In water environments, bacteria in the water can also fix nitrogen gas into ammonium. Ammonium can be used by aquatic plants as a source of nitrogen. Nitrogen also is released to the environment by decaying organisms or decaying wastes. These wastes release nitrogen in the form of ammonium. Ammonium in the soil can be turned into nitrate by a two-step process completed by two different types of bacteria. In the form of nitrate, nitrogen can be used by plants through the process of assimilation. It is then passed along to animals when they eat the plants. Turning nitrate back into nitrogen gas, the process of denitrification, happens through the work of denitrifying bacteria. These bacteria often live in swamps and lakes. They take in the nitrate and release it back to the atmosphere as nitrogen gas. Just like the carbon cycle, human activities impact the nitrogen cycle. These human activities include the burning of fossil fuels, which release nitrogen oxide gasses into the atmosphere. Releasing nitrogen oxide back into the atmosphere leads to problems like acid rain.

Ex Output:
the initial step of producing a nitrogen containing compound from nitrogen in the soil is

The actin-cross-linking protein spectrin is a prominent component of the membrane cytoskeleton. Spectrin is a tetramer of two antiparallel alphabeta-dimers which share a unique and ancient gene structure. The alpha-spectrin and beta-spectrin genes are composed primarily of tandemly repeated 106-amino-acid segments, each of which forms a triple alpha-helical coiled coil. Both the genes and the repeats themselves are homologous. The two genes are thought to be the result of a gene duplication event, and each gene is the product of duplications of the 106-amino-acid repeats. In this work we compare the process of molecular evolution across the repeated segments of the alpha- and beta-spectrin genes. We find that the alpha-spectrin segments have, for the most part, evolved in a homogeneous fashion, while considerable heterogeneity is found among beta-spectrin segments. Several segments with unique known functions are found to have evolved differently than the others. On the basis of heterogeneity of the evolutionary process, we suggest that at least one repeat has a unique function that has yet to be documented. We also present new statistical methods for comparing the evolutionary process between different regions of DNA sequences.

Ex Output:

Alpha-spectrin and beta-spectrin subunits form parallel or antiparallel heterodimers?
