During DNA replication, the unwinding of strands leaves a single strand vulnerable. How does the cell protect these strands from damage? How would you identify the protein that serves as a ...

In this type of pairing, adenine (A) forms two hydrogen bonds with thymine (T) in DNA or uracil (U) in RNA, while guanine (G) forms three hydrogen bonds with cytosine (C). These base pairs are highly ...

Whether it is a microbe, a rose, or a dolphin, any form of life gets its building and operating instructions from the molecule of life, DNA. DNA comprises ... known as messenger RNA, makes a ...

An analogous process occurs during chromosomal DNA replication, whereby the 5’-RNA segments that prime discontinuous synthesis of Okazaki fragments are excised, and the intervening gaps are filled in ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

DNA achieves this feat of storing, coding and transferring biological information though its unique structure. Replication of DNA DNA replication is the process by which a cell makes an identical ...

By inhibiting the DNA polymerases, BKC enhances the endogenous RS in cancer cells, leading to increased DNA damage. IBC specifically inhibits CHK2 to prevent DNA repair. The combined use of BKC and ...

including DNA replication and repair, mRNA maturation, and pre-rRNA processing. To safeguard DNA and RNA from nonspecific cleavage by these molecular scissors, our cells support elegant mechanisms of ...
