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
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 statements is/are correct regarding PCR (Polymerase Chain Reaction)? 1. In this reaction, multiple copies of the gene (or DNA) of interest is synthesized in vitro using two sets of primers (small chemically synthesized oligonucleotides that are complementary to the regions of DNA) and the enzyme DNA polymerase. 2. Real-time RT–PCR is a nuclear-derived method for detecting the presence of specific genetic material in any pathogen, including a virus (COVID-19).  Select the correct answer using the code given below.
A polymerase chain reaction (PCR) was set up with the following reagents: DNA template, Taq polymerase, buffer, dNTPs, and Mg2+. Which one of the following is missing in the reaction mixture?
A polymerase chain reaction was performed beginning with 400 template DNA molecules in a 100 μL reaction. After 20 cycles of polymerase chain reaction, how many molecules of the amplified product will be present in 0.1 μL of reaction?
An in vitro translation system can synthesize peptides in all three reading frames of the RNA template. When 5' - UCUCUCUC-(UC)n-UCUCUCUC - 3' was used as the template in this in vitro translation system, the synthesized peptides contained 50% each of serine and leucine. When 5' - CCUCCUCCU-(CCU)n-CCUCCU - 3' was used as the template, the synthesized peptides contained 33.3% each of serine, leucine, and proline. Deduce the codon for proline.
