The flow of genetic information in molecular biology follows the following path, A) DNA is translated into protein B) DNA is transcribed into RNA which is translated into protein C) DNA is translated into RNA which is transcribed into protein D) RNA is transcribed into protein
Answer:
The Correct answer is DNA is transcribed into RNA which is translated into protein
Explanation:
The genetic information is unidirectional, from DNA to proteins. First, DNA is transcribed into an intermediary RNA molecule is known as transcription (TC), a further messenger RNA molecule (mRNA) is translated into a corresponding sequence of amino acids (translation). This concept of information flow is known as the central dogma of molecular biology.

Which phrase describes air pressure?
decreases with denser air
decreases as altitude decreases
equals mass divided by volume
decreases as a result of fewer air particles pushing down
The phrase which best describes air pressure is: decreases as a result of fewer air particles pushing down.
What is pressure?Pressure can be defined as a measure of the force exerted per unit area of an object or physical body. Thus, it is usually measured in Newton per meter square and calculated by using this formula:
[tex]P = \frac{F}{A}[/tex]
Where:
P is the pressure.F is the force.A is the area.The types of pressure.In Science, there are different types of pressure and these include the following:
Hydrostatic pressureOsmotic pressure Filtration pressureAtmospheric (air) pressureIn conclusion, air pressure is also referred to as atmospheric pressure and it generally decreases due to fewer air particles pushing down on the surface of planet Earth.

Which represents the complimentary base pairing rule for DNA replication?
Adenine pairs with guanine and cytosine, pairs with thymine
Adenine pairs with cytosine, and guanine pairs with thymine
Guanine pairs with cytosine, and adenine pairs with thymine
Guanine pairs with uracil, and adenine pairs with cytosine
Answer:
C
Explanation:
You will need to follow Chargaff's rules.
Adenine always pairs with thymine and cytosince always pairs with guanine.
Guanine pairs with cytosine, and adenine pairs with thymine is the base pairing rule for DNA replication.
What is DNA?DNA exists abbreviation of deoxyribonucleic acid, an organic chemical of complicated molecular structure that exists found in all prokaryotic and eukaryotic cells and numerous viruses. DNA codes genetic announcement for the transmission of inherited traits. Each strand of a DNA molecule exists comprised of a long chain of monomer nucleotide. The nucleotide of DNA consists of a deoxyribose sugar molecule to which stands connected a phosphate party and one of four nitrogenous bases.

A person lives on the Tropic of Capricorn. What is the altitude of Polaris?
O 23 1/2"
O 90°
O 66° 33"
O 15°
O 30°
O 45°
The correct answer as to what the altitude of Polaris would be for a person that lives on the Tropic of Capricon is 23° 1/2".
Polaris is a star and the altitude of any star is its height above the horizonThe Polaris is otherwise known as the North star as an indication that it is directly located overhead the north pole. Thus, it may not be visible once one moves South of the equator. The tropic of Capricon is located approximately 23° 1/2" South of the equator. In other words, the latitude of the Tropic of cancer is approximately 23° 1/2".Hence, the altitude of the Polaris at an altitude of 23° 1/2" will also be 23° 1/2", although it will most likely remain invisible.A person that lives on the Tropic of Capricon is approximately on latitude 23° 1/2". Since the altitude of a star is its height above the horizon, the altitude of Polaris from the Tropic of Capricon would, therefore, be 23° 1/2"

Due to the partial charges on atoms in a water molecule, ____ in water molecules are attracted to oxygen atoms in other water molecules.
Hydrogen bond in water molecules are attracted to oxygen atoms in other water molecules.
A hydrogen bond is a strong dipole-dipole attraction which occurs between:
the hydrogen atom attached to a strongly electronegative atom (for example oxygen in water molecules)another strongly electronegative atom with a lone pair of electronsHydrogen bonding occurs in the following compounds which include water, hydrogen fluoride and ammonia.
When an electronegative atom such as oxygen is bonded to hydrogen, a dipole develops causing the hydrogen to be partially positive while the other atom is partially negative.
Thus, this accounts for high boiling point in compounds that contains hydrogen bonds.

How many electrons are contained in a single covalent bond
hi <3
there would be 2 electrons. each atom shares an electron each so in a single covalent bond, there would be 2 electrons
hope this helps :)
There are two electrons in a covalent bond.
Deeper meaning:-A covalent bond can be meant of as a 'shared pair' of electrons, so there are 2 electrons in each bond. This means that a double bond will have 4 electrons in the space between the bonded nuclei, and a triple bond will have 6.
