Who were the first to suggest that one strand of DNA might act as a template for the synthesis of its complementary strand?

Correct Answer: Watson and crick
In Watson and Crick’s paper on the model of DNA double helix they ended with a statement that it had not escaped their notice that the specific pairing they had postulated immediately suggested that one strand might be the template for the complementary strand synthesis.

Consider the following statements regarding DNA replication and choose the correct answer:
1. The very first requirement of DNA synthesis is the presence of a template or plan along which the new strand is to be constructed
2. The second requirement is of a DNA-dependent-DNA polymerase or simply DNA polymerase enzyme
3. A DNA Pol cannot join two free nucleotides; one of them must be anchored by hydrogen bonds to a DNA strand
4. Replication takes place bidirectionally

Consider the following statements regarding chain elongation during DNA synthesis and choose the correct answer:
1. The separated strands are kept open by DNA binding proteins (DBPs)
2. A DNA chain is initiated on the 3'- OH end of the primer
3. Okazaki fragments are synthesized on one strand; there is continuous DNA synthesis in the other strand
4. Okazaki fragments are joined by endonuclease

Watson and Crick’s suggestion of the complementary strand synthesis taking one of the parent strand as template was proposed in _________

You transcribe a gene and obtain mRNA. To detect which strand is transcribed you replicate each strand in vitro and use the newly synthesized strand for hybridization with mRNA. If mRNA hybridize with the newly replicated strand from 1st strand then the gene transcribed was in ________

The sequence can also be verified by making an oligonucleotide primer complementary to the distal part of the readable sequence and using it to obtain the sequence of the complementary strand on the original DNA template.

Word 2010 has a particular template that it uses when you first open the program. This template contains default styles, no text and you also use it when you create new, blank documents. As you customize styles, marcos and other elements these settings are automatically stored in this template. What is the name of this template file?

Which of the following enzymes catalyses the synthesis of RNA molecules complementary to single-strand DNA template?

Consider the following statements regarding cell cycle and choose the correct answer:
1. During G1 phase the cell grows in size and there is an active synthesis of RNA and proteins
2. The third stage of the cell cycle is termed G2 phase
3. In the mitotic phase, the DNA molecule of each chromosome replicates by the synthesis of a new DNA molecule on the template of the existing DNA

Base sequence of each parental strand considered to synthesis new complementary strand.

A : T ratio in one strand of DNA duplex is 2, what will be the ratio in the complementary strand
