conjunctivitis can be caused by both bacteria and viruses. bacterial infections often present with a discharge, whereas a clear exudate is characteristic of infections. neonates can suffer from conjunctivitis following a birth if the mother has an active infection of either neisseria gonorrhoeae or .
The mother has an active infection of either neisseria gonorrhoeae or Gonococcal conjunctivitis tht is developed in newborn.
However, pregnant girls with gonorrhea can transmit the contamination to their infants all through vaginal delivery. This occurs due to the fact the toddler comes into touch with the mother's genital secretions. Symptoms in inflamed babies generally seem to 5 days after delivery. Conjunctivitis can end result from many causes, which include viruses, bacteria, allergens, touch lens use, chemicals, fungi, and sure diseases.
This is resulting from micro organism known as Neisseria gonorrhea. A new child infant can select out up this form of micro organism throughout vaginal beginning from an inflamed mother. This extreme form of conjunctivitis can be averted with using eye drops in newborns at beginning.

Covalent modification generally turns off genes by attracting proteins that bind to methylated cytosines and block gene transcription.
a) DNA Methylation
b) miRNA
c) RNAi
d) tRNA
The correct option among the following was DNA Methylation.
define DNA Methylation ?
A biological process called DNA methylation involves the addition of methyl groups to the DNA molecule. Without altering the sequence, methylation can modify the activity of a DNA region. DNA methylation often suppresses gene transcription when it occurs at a gene promoter. DNA methylation plays an important role in a variety of critical processes in mammals, including ageing, cancer, X-chromosome inactivation, genomic imprinting, and transposable element suppression.
Adenine and cytosine are the two nucleobases on which natural, enzymatic DNA methylation occurs as of 2016. N6-methyladenine[1], 5-methylcytosine[2], and N4-methylcytosine are the modified bases. [3]
The DNA nucleotide cytosine is methylated to create 5-methylcytosine at position 5 on the pyrimidine ring. This is the same place that separates thymine from the homologous RNA base uracil, which has no methyl group. 5-Methylcytosine undergoes spontaneous deamination and is changed into thymine. A T:G mismatch emerges from this. If A is substituted for G, the original C:G pair becomes a T:A pair, thus altering a base and producing a mutation. Repair mechanisms then fix it back to the original C:G pair.

energy yielding nutrients include
Energy yielding nutrients include fats, carbohydrates, and proteins as they provide energy to the body.
How does these three nutrients provide energy?Fats :
Lipids are another name for fats. Fat is the nutrient with the highest energy density or energy content, with 9 calories per gram of fat. The second most prevalent form of nutrient in food is fat. They give the body's cells the energy they need to function, and they also support strong immune systems and healthy skin and hair. For future usage, such as during pregnancy or when energy needs alter, fats are stored in fat cells. Foods like seeds, nuts, seafood, dairy products, and vegetable oils are sources of unsaturated fats.Carbohydrates:
The most prevalent form of nutrient in meals is carbohydrate. They are in charge of bringing sweetness to fruits and vegetables.Energy can be obtained from both simple and complex carbs, but only complex carbohydrates also include vitamins and minerals.Simple carbs consist of starch and sugar (glucose) (polysaccharides). Fruit sugars (fructose), milk sugars (lactose), and grain sugars are examples of complex carbohydrates (maltose and galactose). Another kind of carbohydrate is fiber. For those trying to reduce weight, a diet high in complex carbs and low in processed foods is advised.Proteins:
Protein is an excellent source of fuel for the body, and it can aid in muscle recovery and help you feel your best after working out.Thus, if you lead an extremely active lifestyle, protein can be highly advantageous.A macronutrient is referred to as protein. This indicates that it is a nutrient that the body need in significant amounts for energy and as a crucial component of any diet.Although it is most frequently found in animal products, plant-based sources like nuts and legumes also contain a significant amount of it. Everyone is aware that the body needs food for energy. But you might not be aware that a significant amount of the body's energy comes from protein.What is energy yielding nutrient?The nutrients in meals that the body really uses to produce energy are known as energy-yielding nutrients. The macronutrients are another name for them. Micronutrients and macronutrients are both types of nutrients. A lot of macronutrients are required, and the majority of them are energy-giving (fiber is sometimes considered a macronutrient but does not provide energy). Micronutrients are necessary in small amounts to ensure that various bodily functions run smoothly, but because they do not instantly convert to energy, they are not considered to be an energy-yielding nutrient.

Multipolar neurons are neurons from the central nervous system. They are composed of an ovoid cell body with several dendrites emerging from it, a long axon, and axon terminals. Graded potential occurs in the neuronal soma, while action potential occurs in the axon.
What is a multipolar neuron?
Neurons are formed in general by
A cellular body, soma,Dendrites, which are cytoplasmic extensions that receive stimuli from other cells, and An axon, which is a long formation capable of conducting the electrochemical signals.
Multipolar neurons are the ones that have a single axon and several dendrites.
Dendrites emerge from an ovoidal soma, and extend in different directions, creating a net and increasing the neuronal area to receive stimuli.
Axons are very large and covered by Schwann cells, facilitating impulse transmission.
These neurons are usually located in the central nervous system and integrate information coming from other nerve cells.
Every neuron forms connections with other neurons. These connections are known as synapsis.
As it happens in every synapsis between neurons when a presynaptic neuron sends information, a neurotransmitter is released.
Neurotransmitters are chemical substances that travel through the synaptic cleft to the junctional area of the other neuron and bind to its receptors in the postsynaptic membrane.
This binding produces a depolarization of the cell called an excitatory postsynaptic potential.
Graded potential initiates in the soma and dendrites.An action potential is initiated in the axon and spreads to the rest of the membrane depolarizing it.

agine that you have a sample of dna that contains a single, specific dna sequence. before you run your gel, you split your sample into two tubes. you run the dna from the first tube in lane two of your gel. you take the other tube and use an enzyme called a restriction enzyme that cuts the dna into two pieces at a specific point in the sequence. you then run this sample that was cut on the gel. which of the next three lanes (lane 3, 4, or 5) could be the same sample from lane two after it was cut into two pieces?
After being divided into two halves, the sample from lane two may still be present in lane 4, which is possible. Lane 2 is around 700 base pairs long, and lane 4 will add up to about 700 base pairs as well, despite the restriction enzyme that divides the DNA into two parts.
What is gel electrophoresis?
A laboratory technique called gel electrophoresis is used to divide combinations of DNA, RNA, or proteins based on their molecular sizes. In gel electrophoresis, the molecules that need to be separated are forced through a gel that has tiny holes by an electrical field.It involves an electrical field, specifically one that is applied such that the gel has a positive charge on one end and a negative charge on the other. Negatively charged molecules like DNA and RNA will be drawn to the positively charged end of the gel. However, because proteins lack a negative charge, they must first be combined with sodium dodecyl sulfate, a detergent, in order to separate them using this method. The proteins are given a linear structure and a negative charge during this process, enabling them to move toward the gel's positive end and be separated. Finally, after utilizing it to separate the DNA, RNA, or protein molecules, bands representing of different molecular sizePrinciple of gel electrophoresis:
Since DNA is negatively charged, it will move toward the positively charged electrode when an electric current is supplied to the gel. The DNA fragments are organized in size order because shorter DNA strands travel through the gel more quickly than longer ones.
