科技日报北京9月1日电 （记者张梦然）DNA因其标志性的双螺旋结构而广为人知。但澳大利亚加文医学研究所科学家发现，人类基因组还含有超过5万个不寻常的结状DNA结构，称为i-基序。最新一期《EMBO》杂志发表了这些独特DNA结构的第一张综合图谱，揭示了它们在 ...

each A in one strand always pairs with a T in the other strand, and each C always pairs with a G. The double-stranded DNA that results from this pattern of bonding looks much like a ladder with ...

It’s aged — 3,600 years. Scientists have successfully pulled a DNA strand from what they believe to be the world’s oldest cheese, yanking it from Bronze Age mummies in a Chinese graveyard ...

Sep. 25, 2024 — Scientists successfully extracted and analyzed DNA from ancient cheese samples found alongside the Tarim Basin mummies in China, dating back approximately 3,600 years.

In these sequences, the letters of the genetic code, the four base molecules adenine, cytosine, thymine and guanine, are ordered such that they have the same order as the second complementary ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

DNA is the molecule that holds the instructions for all living things. DNA achieves this feat of storing, coding and transferring biological information though its unique structure. Replication of ...

The 2024 Albert Lasker Award for Basic Medical Research is awarded to Zhijian (James) Chen for his landmark discoveries that explain how DNA stimulates immune responses. DNA is best known as ...

RNA polymerase moves along the DNA strand. Free RNA nucleotides form hydrogen bonds with the exposed DNA strand nucleotides by complementary base pairing to form a strand of mRNA: Note - RNA ...
