Both strands of DNA cannot act as a template for transcription because of the following reasons: i. It would code for RNA molecules with different sequences, leading to formation of two different polypeptide chains from the same segment of DNA. ...
What is responsible for holding the two strands together in the DNA double helix? What builds new strands of DNA? One strand of the DNA molecule runs 5' to 3'. The other strand runs 3' to 5'. This makes the two strands what?
DNA replication is a biological process that involves the duplication of double-stranded DNA (dsDNA) molecules. A dsDNA molecule consists of two antiparallel strands that are joined with each other by hydrogen bonds. During replication, each strand serves as a template strand f...
Interaction forces between single strands of DNA were measured with the atomic force microscope by a procedure in which DNA oligonucleotides were covalently attached to a spherical probe and surface. Adhesive forces measured between complementary 20-base strands fell into three distinct distributions center...
Only one of the two complementary strands of a restriction fragment hybridizes under low stringency conditions to a cloned Arabidopsis thaliana genomic DNA fragment. We propose that this effect is caused by the energetic nonequivalence of the two possible mismatched duplexes, resulting from the accumu...
Jovin and co-workers have demonstrated that DNA strands containing guanine-adenine repeats generate a parallel-stranded homoduplex. Here we propose that the homoduplex is a dimer of the ordered single strand discovered by Fresco and co-workers at acid pH. The Fresco single strand is shown here ...
According to base -pairing principle. G faces, C,T faces A and vice -versa in the complimentary strand of DNA. Thus , the sequence of bases in the complementary strand is : 3'-C-T-T-A-T-G-G-C-C-A-T-5'. (ii) Since the complimentary strands run in the o
This article is a perspective on the separation of the complementary strands of DNA during replication. Given the challenges of DNA strand separation and its vital importance, it is not surprising that cells have developed many strategies for promoting unlinking. We summarize seven different factors ...
