Answer:
The question lacks options, the options are:
A) No proofreading will occur. B)The DNA will supercoil. C)Replication will occur via RNA polymerase alone.
D)No replication fork will be formed.
E)Replication will require a DNA template from another source.
The answer is D
Explanation:
Prior to division of any cell, its genetic material needs to be replicated. Ideally, in a bacterial cell, this replication starts at a particular nucleotide sequence called ORIGIN OF REPLICATION. An enzyme called DNA HELICASE then binds to the origin of replication and breaks the hydrogen bonds between the double-stranded DNA molecule to form a Y-shaped Replication fork, which serves as a template for DNA polymerase III to bind and begin to add nucleotides.
However, if a mutation occurs at a certain gene dNAb and alters the action of HELICASE enzyme. Thus, it prevents the helicase from separating the double-strands of the DNA molecule containing the gene. Hence, no replication fork will be formed and subsequently no template for DNA polymerase's action.
Answer:
b. Chromatin remodeling
Explanation:
During initial stages in RBCs, the myoglobin gene expression is restricted through chromatin remodeling. <u>Chromatin remodelers which belong to CHD family are involved in chromosome condensation which mask the euchromatin portion of chromosomes containing genes for myoglobin expression with the help of histone proteins.</u> This leads to the masking of genes of myoglobin genes in RBCs and their expression does not take place.
Note: Mature red blood cells (RBCs) are dead cells and their only function is to transport the oxygen and nutrients to various body parts so they don't need to express any other gene than hemoglobin. RBCs become dead during later stages of their maturation, at that time their entire nucleus is degenerated but before doing that RBCs synthesize enough copies of hemoglobin gene product. This process is known as gene diminution.
Yes, the human body is an ecosystem too in the end. We have that around 3.5 kg of microorganisms inside us.Most of them are indifferent to our existence and are hitchhikers on a ride or have minimal consequences on us. Some of them want to harm us and are called pathogens. Viruses and other pathogens are dependent on our cells in order to multiply and propagate themselves. Finally, there are also vacteria that benefit us; many studies have showcased that the bacterial communities in our stomach can help prevent various diseases and also attack some invaders. In this case, since the bacteria feed on us, both parties benefit and this relationship of interdpendence is called symbiosis.
