What is RNA primase's job?
-removing a few bases for DNA polymerase
-add a few bases for DNA polymerase
-removing a few bases for helicase

Answers

Answer:

The correct answer is - add a few bases for DNA polymerase

Explanation:

A short extended nucleic acid composed of ssRNA molecule. This is a molecule that synthesize a primer initialy and later again lay down a primer after the opening of replication fork by DNA helicase.

It sysntheisze before and after the helicase and follow the helicase in order to prepare for the replication process. Thus, adding a few bases for DNA polymerase is main job of RNA primase.

Only answer if you know the answer

Answers

Answer:

B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules

Explanation:

DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.

In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.

true or false:

Fish are considered carbon-based organism

Answers

Answer:

Its how you see it.

Explanation:

1.Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.

2.All life on earth can be thought of as "carbon-based." Just be careful about turning this around backwards. It is true that all living things contain carbon compounds... but the opposite is not true. Just because a certain material is referred to as organic does not mean it is or ever was alive.

what happens to the chemical bonds during chemical reactions

Answers

During chemical reactions, the bonds that hold molecules together break apart and form new bonds, rearranging atoms into different substances. Each bond requires a distinct amount of energy to either break or form; without this energy, the reaction cannot take place, and the reactants remain as they were. Simplisticly said During chemical reactions, the chemical bonds between atoms are altered.

Explain how the stomach Depends on other body systems to carry out its role in breaking down food molecules.

Answers

The whole body works together, as a “team.”If one of the parts of the body won’t work together as a team, everything will get messed up. The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces. An acidic environment is needed for the digestion that takes place in the stomach.

explain the flow of energy of candles

Answers

Answer:

The wax vapor catches light and burns, sending a flame high above the wick. Heat from the flame travels in three directions at once by processes called conduction, convection, and radiation. Convection draws hot wax vapors out from the wick and sucks oxygen from the surrounding air into the base of the flame.

Explanation:

Answer:

The heat from the wick melts the wax which gets absorbed in the wick and then gets burnt (which is really oxidation) to produce heat energy as well as light energy. The energy transforms from chemical energy to heat and light energy. Because when the candle burns a chemical reaction occurs, and produces heat and light.
