Dr Maramura
Dr Tafadzwa Maramura says she carved her path by remaining focused and resolute on her journey.

The African proverb ‘it takes a village to raise a child’ conveys the message that it requires many people to provide a safe and healthy environment for children. The village gives the child the security needed to develop and be able to realise their hopes and dreams. 

Dr Tafadzwa Maramura believes that the same applies vice versa. “It takes a good child to be raised by a village. You need to understand that the village can only do so much, the rest lies on your shoulders as the child,” she says.

The journey of a child raised by a village
The senior lecturer reflects on the journey that led her to serve in the Department of Public Administration and Management at the University of the Free State. At the age of three, she lost her father, who was an army general in Zimbabwe. Soon after, her academic journey would begin at a boarding school. Her widowed mother then moved her to a mission school due to financial constraints, seeing that she had two more children relying on her for survival. Since her father served in the government, she qualified for a state scholarship, which saw her launch her academic career in South Africa as an undergraduate student. 

“I came to South Africa in 2010 and pursued a Bachelor of Social Science degree in Development Economics at the University of Fort Hare. Once my honours were conferred, I acquired my master’s within a year. Thereafter, I enrolled at the North-West University, where I completed my PhD within two years.”

Dr Maramura was the Vice-Chancellor’s valedictorian for her bachelor, honours, and 
master’s degrees. Graduating cum laude was another way of ensuring that she pays it forward to the village that raised her. Not only was she funded by the Zimbabwean government, but she also received financial aid from South Africa throughout her studies. 

Once a child, now part of the village 
Today, as founder of a foundation based in Zimbabwe, she pays the fees of orphaned and disadvantaged primary school learners. “I wish everyone could adopt a child, pay their fees, buy their schoolbooks – because we only have each other, we do not have anyone else. That’s also part of what I call co-creating.”

The Brightest Young Minds in Africa alumna goes above and beyond focusing on academics, as she believes that “if you are the only one holding the light, everyone else will have to follow behind you to make sure that they can see ahead. However, if you share that light, then it means many more can see, therefore making it easier to solve societal challenges as a collective”.

She argues that the amount of money you spend on lunch could pay a child’s school fees for a term, and the cash that you use to buy a jacket or a pair of shoes, could cover a child’s fees for a month.
Making a difference in the lives of young children is her way of playing the role of the village now that she is an adult. “I make sure that wherever I am, I make an impact in the lives of others.”

Dr Maramura says she plans to make sure that life is better for the next young African female, by setting up a mentorship programme for the next generation of leaders. In addition to that, her goal is to become an associate professor, rise in academic rank, and develop a research unit that can speak to issues of sustainable service delivery.

On how to be a good child 
You do not need to be a figure of authority to make an impact. According to Dr Maramura, all you need is a desire to co-create, and making sure that the public is in a different place after you have left the relevant office you hold or the organisation you serve. “Make sure that you can co-exist, because humans don’t live in a vacuum, we exist among each other.”

Serving the people makes all the difference. She suggests that everyone asks themselves what they are doing for their community, class, or family.

UFS study on cell development in top international science journal
2008-09-16

A study from the University of the Free State (UFS) on how the change in the packaging of DNA with cell development influenced the expression of genes, will be published in this week’s early edition of the prestigious international, peer-reviewed science journal, the Proceeding of the National Academy of Sciences of the USA (PNAS).

The PNAS journal has an impact factor of 10, which means that studies published in the journal are, on average, referred to by ten other scientific studies in a two year period. The South African Journal of Science, by comparison, has an impact factor of 0.7.

The UFS study, funded by the Wellcome Trust and the National Research Foundation (NRF), looked at how the change in the packaging of DNA with cell development influenced the expression of genes. It is very relevant to research on stem cells, an area of medicine that studies the possible use of undifferentiated cells to replace damaged tissue.

Prof. Hugh Patterton, of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, who led the study, said: "We are extremely proud of this study. It was conceived in South Africa, it was performed in South Africa, the data were analysed in South Africa, and it was published from South Africa."

When a gene is expressed, the information encoded in the gene is used to manufacture a specific protein. In eukaryotes, which include humans, there is approximately 1m of DNA, containing the genes, in every cell. This length of DNA has to fit into a cell nucleus with a diameter of only about 10 micrometer. In order to fit the DNA into such a small volume, eukaryotic cells wrap their DNA onto successive protein balls, termed nucleosomes. Strings of nucleosomes, resembling a bead of pearls, is folded into a helix to form a chromatin fiber. The study from the UFS investigated how the binding of a specific protein, termed a linker histone, that binds to the length of DNA between nucleosomes, influenced the formation of the chromatin fiber and also the activity of genes.

"We found that the linker histone bound to chromatin in yeast, which we use as a model eukaryote, under conditions where virtually all the genes in the organism were inactive. It was widely believed that the binding of the linker histone caused the inactivation of genes. We studied the relationship between the amount of linker histone bound in the vicinity of each gene and the expression of that gene for all the genes in yeast, using genomic techniques. We made the surprising discovery that even through the linker histone preferentially bound to genes under conditions where the genes were shut off, this inactivation of genes was not caused by the binding of the linker histone and folding of the chromatin,” said Prof. Patterton.

He said: “Instead our data strongly suggested that the observed anti-correlation was due to the movement of enzymes along the DNA molecule, involved in processing the information in genes for the eventual manufacture of proteins. This movement of enzymes displaced the linker histones from the DNA. This finding now requires a rethink on aspects of how packaging of DNA influences gene activity."

Prof. Patterton said that his research group, using the Facility for Genomics and Proteomics as well as the Bioinformatics Node at the UFS, was currently busy with follow-up studies to understand how other proteins in nucleosomes affected the activities of genes, as well as with projects to understand how chemicals found in red wine and in green tea extended lifespan. "We are certainly having a marvelous time trying to understand the fundamental mechanisms of life, and the UFS is an exciting place to be if one was interested in studying life at the level of molecules," he said.
