Answer:

Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow. Some live in or on other organisms including plants and animals including humans. There are approximately 10 times as many bacterial cells as human cells in the human body.

In this activity, you will determine whether each statement relates to DNA or to RNA. Based on your knowledge of DNA and RNA str

erma4kov [3.2K]

Answer:

it is double-stranded in cells and most DNA viruses - DNA

the nitrogen-containing bases are adenine (A), cytosine (C), guanine (G), and thymine (T) - DNA

it functions by determining the heredity of trait - DNA

the pentose sugar is deoxyribose - DNA

it is double-stranded in cells and most DNA viruses - DNA

Explanation:

-it is double-stranded in cells and most DNA viruses

-the nitrogen-containing bases are adenine (A), cytosine (C), guanine (G), and thymine (T)

-it functions by determining the heredity of trait

-the pentose sugar is deoxyribose

The DNA (deoxyribonucleic acid) is a double stranded molecule that has been found to be responsible for heredity of traits. It is characterized by 3 main components:

A phosphate group
A deoxyribose sugar
Purine and or pyrimidine bases

The purine bases include Adenine and Guanine while the pyrimidine bases include Thymine and Cytosine.

The DNA differs from RNA in that the RNA (ribonucleic acid) is single stranded, contains ribose sugar and instead of Thymine base, it contains Uracil.

Which of the following is/are required for the polymerization reaction catalyzed by DNA polymerase III?

Temka [501]

Answer:

D. I, IV, VI, and VII

Explanation:

DNA polymerase III has both 5' to 3' polymerization activity and 3' to 5' exonuclease activity (the proofreading). DNA pol III requires divalent magnesium ions for its polymerization and proofreading activities. Here, the magnesium ions serve as cofactor.

DNA polymerase III cannot start the process of synthesis of new DNA strand de novo and uses an RNA primer synthesized by primase enzyme. The polymerization activity of DNA polymerase III elongates the RNA primer in 5' to 3' direction. The primers are removed by 5' to 3' exonuclease activity of DNA polymerase I.

During polymerization, the DNA polymerase III uses existing DNA strand as a template. The four dNTPs namely deoxyadenosine triphosphate (dATP), deoxycytidine triphosphate (dCTP), deoxyguanosine triphosphate (dGTP) and deoxythymidine triphosphate (dTTP) are added to the RNA primer according to the sequence of DNA template.

Use evidence from the diagrams of macromolecules and information provided earlier to revise your explanation about whether sugar

defon

Answer:

Sugar molecules do NOT provide all the elements needed to make the four types of macromolecules.

Explanation:

This is because proteins, and amino acids need more types of elements than carbohydrates and lipids do. In nucleic acids, the elements are carbon, hydrogen, oxygen, nitrogen, and phosphorus. Notice that sugar molecules do not have either nitrogen or phosphorus. This same principle applies to proteins, which the elements of it are carbon, hydrogen, oxygen, and nitrogen.
