Mistakes can happen during DNA replication, and if they are not repaired it can result in a mutation. Certain mutations can lead

polet [3.4K]

Mutations result either from errors in DNA replication or from the damaging effects of mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides. All cells possess DNA-repair enzymes that attempt to minimize the number of mutations that occur

A nucleotide of DNA may contain ________.

aleksklad [387]

Answer:

The correct answer will be option- deoxyribose, thymine, and a phosphate group.

Explanation:

Deoxyribose nucleic acid or DNA is a type of nucleic acid which acts as genetic material in the organisms.

Each strand of DNA is made up of nucleotide which is made up of a 5 carbon sugar called deoxyribose, a phosphate group and 4 types of nitrogenous bases mainly adenine, thymine, guanine and cytosine. The sugar and phosphate form the backbone of the DNA molecule while the nitrogenous bases are stacked perpendicular to the backbone.

Thus, option- deoxyribose, thymine, and a phosphate group.

_____ splits water into 1/2 O2, H , and e- . A structure of a thylakoid. Letters from A to E indicate definite structures. Lette

Sauron [17]

The luminous reactions begin when light reaches photosystem II. The water molecules provide electrons to the photosystem, releasing oxygen and protons. The letter A represents photosystem II that splits water.

-----------

1. Luminous energy is trapped by chlorophyll in Photosystem II.

2. When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.

3. The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.

4. When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules.

5. Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.

6. When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II.

7. When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.

8. The released energy is used to produce ATP molecules.

9. Hydrogen ions go back from the stroma to the thylakoid compartment.
