从此以后,人们将在复制叉中不连续合成的DNA片段称为冈崎片段(Okazaki fragment),同时采纳了Okazaki最初的建议,将连续合成的DNA子链称为前导链(leading strand),不连续合成的子链称为后随链(lagging strand)或滞后链(图4-11)。图4-11 DNA的半不连续复制...

The double-stranded structure of DNA provides for an elegant mechanism to ensure accurate and faithful replication and repair of the DNA – thegeneticinformation stored in one strand is also encoded in its complement. To take advantage of the properties of complementary base pairing, the two stran...
Fig. 2.1. The structure of DNA. (1) A schematic drawing of the DNA double helix. Two complementary strands (i.e., the base adenine always pairs with thymine; cytosine with guanine) run in opposite directions: The sense strand 5′→ 3′ and the antisense 3′→ 5′. (2) An expanded...
The bases of each strand link together viahydrogen bonds. Adenine and Guanine are purines as they have two rings in their molecular structure. Thymine and Cytosine are pyrimidines as they only have one ring in their molecular structure. A purine will link with a pyrimidine. Adenine and thymine...
to-base bonding is not random; rather, 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 sugar-phosphate side supports and base-pair rungs...
Dynamic and static light scattering, CD, and optical melting experiments have been conducted on M13mp19 viral circular single-strand DNA as a function of NaCl concentration. Over the 10,000-fold range in concentration from 100 M to 1.0M NaCl, the melting curves and CD spectra indicate an inc...
Strand displacement amplification substituted, klenow fragment of DNA polymerase I, primers that are complementary to the single strands of the target sequence and further having at the 5' end a recognition sequence of 5'GTPyPuAC3', and HincII; e) hybridizing the... GT Walker - US 被引量:...
DNA double-strand breaks (DSBs) can be caused by environmental agents such as radiation and drugs1,2,3and endogenous metabolism such as transcription and replication stress4,5. For example, normal metabolism has been estimated to cause ~1–50 DSBs per human cell per day6,7. Consequently, fas...
Maurice Wilkins was a New Zealand-born British biophysicist whose X-ray diffraction studies of deoxyribonucleic acid (DNA) proved crucial to the determination of DNA’s molecular structure by James D. Watson and Francis Crick. For this work the three sci
