What is a DNA-binding motif?Gene regulatory proteins:Each second thousands of genes are turned on and off in our bodies but how does each cell know when to turn on, or turn off (express or repress) a specific gene? Each gene contains a regulatory region where specific proteins interact ...
What is a DNA sweep? DNA Evidence: In the modern world, the advancement of technology has resulted in the evolution of new techniques for identifying a criminal suspect. Analysis of DNA samples stands out as one of the best methods of identifying the key suspect of a crime. The analysis of...
The protospacer adjacent motif (PAM) is a shortDNAsequence (usually 2-6 base pairs in length) that is about 3-4 nucleotides downstream from the DNA sequence targeted by Cas9. Cas9 cannot bind to or cleave the target DNA sequence if it is not followed by the PAM sequence....
I eat for breakfast with eggs and avocados. I put herbs in a mason jar with water and it’s like having a flower arrangement in your fridge. And don’t get me started on the wonders of fish sauce… I was born on a rice farm in Vietnam, the stuff is in my DNA.” Robert Sisca...

Prior to AFDB, teams of scientists would spend months, even years, solving a structure of a single protein, whereas nowadays, thanks to AFDB, protein structure is often taken as a given. However, we and others [Citation26] advise caution given that, although informative, all structural models...
What is a gene? What is the complementary RNA sequence of the DNA sequence GAACCGT? Fill in the blank: Genes that are located close to each other on the same chromosome are referred to as ___ genes. DNA sequences that are very similar in related species or genes are called ___. Wha...
Epigenetic memory maintains gene expression states through cell generations without a change in DNA sequence and in the absence of initiating signals. It is immensely powerful in biological systems — it adds long-term stability to gene expression states and increases the robustness of gene regulatory...
domain effector proteins achieve interference by complementarity betweenthe crRNA and the target sequence after recognition of the PAM (ProtospacerAdjacent Motif) sequence, which is adjacent to the target DNA . Theseribonucleoprotein complexes have been redesigned for precise genome editing byproviding a...
