what is the function of DNA and RNA

Answers

Answer: DNA codes for our genotype, which is the genetic representation of out traits. There are multiple kinds of RNA but it is mostly used to aid the replication of DNA.

Explanation: DNA is the strand of nucleic acid, sugars and phosphate group, that is found in the nucleus and mitochondria of every cell. It codes for our genotype, which is essentially the written representation of our traits. There are multiple kinds of RNA but they are mostly used to replicate DNA, they are single stranded as opposed to the double stranded DNA and include the nitrogen base uracil (U), instead of thymine (T). mRNA, tRNA and dsRNA are commonly used to replicate and regulate the DNA sequence.

Answer:

The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell 's activities, while RNA converts that code into proteins to carry out cellular functions.

Explanation:

RNA:

The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins.

DNA:

The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.

A mixture of iron, salt and sand can be separated using a magnet, water, a filter and a hot plate. Think about this separation. The separation of this mixture

Answers

Answer:

Explanation:

This is an example of a mixture which can be separated with simple separation techniques based on the physical properties of the mixtures.Magnetism, and filtration and evaporation

Iron is a magnetic material,but salt and sand are not,Therefore,the iron can be separated from the mixture with the use of magnet.

Salt and sand are mixable.But salt is soluble in water,but sand is not.Therefore by adding the sand and salt to water,the salt will  dissolve,in the water(solvent) to form a salt solution. But the sand can be separated out of the solution by  filtration with the  filter paper inserted into a funnel which allows the salt solution to pass through,while restricting the sand.

The sand would be removed by the filter paper,while solution passes through.

The salt solution and some sand residues is placed in evaporating dish and heated at low temperature. The water from the solution evaporates,leaving the salt behind.

A combination of two are more substances that is not chemically combined is called a mixture.

In order to separate a mixture of iron, salt and sand, we need  a magnet, water, a filter and a hot plate. The magnet is brought close to the mixture and all the iron is removed.

Next, water is added. The water will dissolve the salt while the sand will settle beneath the vessel. The solution can now be filtered and the sand is removed. To recover the salt, the solution is heated using the hot plate until all the water is evaporated and the dry salt is recovered from solution.

1. It produces a very deep sound.

2. It combines the vocal and vestibular folds at the same time.

3. It causes the vibration of the vestibular folds. A vibration cycle culminates at the second vibration.

4. There are basically two types, namely the Dag and Xovu styles.

5. It resembles a Tibetan Buddhist chant.

Explanation:

Khoomii, also known as Tuvan throat singing is a way of singing mostly characterized by the production of deep sounds and vibrations. A basic pitch which is supplemented by another pitch combine to produce the sound.  It is sung by the locals in Siberia and Tuva.

Kargyraa is one of the four forms of this song and it typically involves the production of deep sounds and some vibrations of the vestibular folds at times. There are two basic types which are the Dag and Xovu. It also has a similarity to the chant produced by the Tibetan Buddhists.

Which of the following is essential to proper functioning of all prokaryotic and eukaryotic organisms?

A.) O2
B.) CO2
C.) ATP
D.)NaCI

Answers

Answer:

I think its B. CO2

Explanation:

Oxygen is only needed for eukaryotes so not A

ATP is the product of prokaryotes

And I highly doubt its salt

ATP is essential to the proper functioning of all prokaryotic and eukaryotic organisms.

For example, biochemical reactions in mitochondria switch power from fatty acids and pyruvate molecules into a power-wealthy molecule referred to as adenosine triphosphate (ATP). Subsequently, the relaxation of the organelles uses this ATP because of the supply of the power they want to operate.

Each organelle helps one-of-a-kind sports inside. Mitochondria, for example, are organelles that offer eukaryotes a maximum in their power with the aid of using generating power-wealthy molecules referred to as ATP. Prokaryotes lack mitochondria and rather produce their ATP on their floor membrane

What is enzyme synthesis?

The feature of ATP synthase is to synthesize ATP from ADP and inorganic phosphate (Pi) withinside the F1 sector. This is viable because of power derived from a gradient of protons which move the internal mitochondrial membrane from the intermembrane area into the matrix via the Fo part of the enzyme.

Hence concluded that ATP is essential to the proper functioning of all prokaryotic and eukaryotic organisms.
