Preimplantation Genetic Diagnosis: The Who, the What, the Why and the How

Glossary

RNA (ribonucleic acid)

RNA (ribonucleic acid) is a chemical similar to DNA. Like DNA, RNA contains the chemical bases adenine (A), cytosine (C) and guanine (G), but instead of thymine (T), RNA contains uracil (U).

Blurred boundaries – the language of DNA

08 August 2016 - by Professor Marcus Pembrey

The general public have appropriated the term DNA to mean much more than just the molecule itself. This may not be a problem most of the time but, in the case of donor eggs and sperm in particular, it's important that people are clear on what genetics and epigenetics really tell us... [Read More]

Can donor egg recipients 'pass on DNA' to their children?

02 November 2015 - by Dr Jess Buxton

A recent study suggests that embryonic gene activity may be altered by factors present in the womb even before implantation. This finding triggered a somewhat misleading newspaper article entitled 'Infertile mums "pass on DNA"', which claimed the research means recipients of donor eggs are passing on their own DNA to their child. This isn't the case... [Read More]
