De-novo methylation is done in the newly synthesized DNA strand at opposite positions of the methylated sites on the parent strand.

Correct Answer: False
Maintenance methylation is done in the newly synthesized DNA strand at opposite positions of the methylated sites on the parent strand. In de-novo methylation, addition of methyl groups occurs at totally new positions.

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 ________

Both de-novo methylation and maintenance methylation ensures the methylation pattern is inherited from parent to daughters.

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

At the completion of DNA replication, each newly synthesized DNA strand is

The question below consists of a set of labelled sentences. These sentences, when properly sequenced form a coherent paragraph. Select the mostlogical order of sentences from among the options. P: Young boys and girls seem to have become inordinately addicted to these sites.
Q: The parents, teachers and the government must look into the problems being caused by these networking sites and must formulate a strategy either to curb or completely stop its fast growing negative influence on the minds of our youth.
R: Smart-phones, computers, social media, internet and networking sites such as Facebook and Twitter have become source of major distractions for students.
S: They are thoughtlessly and uselessly wasting their precious time on these sites.

In an experiment you use DNA pol I – Klenow fragment. When all other requisites for replication are added, then what will be the effect on the newly replicated DNA? Consider leading strand only.

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

What is the output of the following code:
class Parent:
def show(self):
print('Parent method')
class Child(Parent):
pass
obj = Child()
obj.show()

What is the output of the following code:
class Parent:
def init(self):
print('Parent constructor')
class Child(Parent):
def init(self):
print('Child constructor')
obj = Child()
