Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

Saudi Arabia lags in CRC screening despite high awareness of early detection benefits

According to the statistics of the Saudi National Cancer Registry issued by the Saudi Health Council for 2020, colorectal cancer (CRC) is ranked second among types of cancer, and first in men and third in women accounting for 12.3% with 1729 cases among all registered cancer cases.

Understanding genetic mosaicism in human cells

In a study led by Jan Korbel at the European Molecular Biology Laboratory (EMBL) and Ashley Sanders at the Berlin Institute for Medical Systems Biology of the Max Delbrück Center (MDC-BIMSB), researchers have found that approximately one in 40 human bone marrow cells carry massive chromosomal alterations – copy number variations and chromosomal rearrangements, for example – without causing any apparent disease or abnormality.

Enzyme implicated in telomere repair offers new avenues for cancer therapy

A new study led by University of Pittsburgh and UPMC Hillman Cancer Center researchers shows that an enzyme called PARP1 is involved in repair of telomeres, the lengths of DNA that protect the tips of chromosomes, and that impairing this process can lead to telomere shortening and genomic instability that can cause cancer.
