<u><em>The nitrogenous base</em></u> is the central information carrying part of the nucleotide structure. These molecules, which have different exposed functional groups, have differing abilities to interact with each other.
<u><em>The second portion of the nucleotide is the sugar.</em></u> Regardless of the nucleotide, the sugar is always the same. The difference is between DNA and RNA. In DNA, the 5-carbon sugar is deoxyribose, while in RNA, the 5-carbon sugar is ribose. This gives genetic molecules their names; the full name of DNA is deoxyribonucleic acid, and RNA is ribonucleic acid.
<u><em>The last part of nucleotide structure, the phosphate group</em></u>, is probably familiar from another important molecule ATP. Adenosine triphosphate, or ATP, is the energy molecule that most life on Earth relies upon to store and transfer energy between reactions. ATP contains three phosphate groups, which can store a lot of energy in their bonds. Unlike ATP, the bonds formed within a nucleotide are known as phosphodiester bonds, because they happen between the phosphate group and the sugar molecule.
Answer:
-Vinegar
-Sugar water
-Soda pop in a sealed bottle
Explanation:
These segments of DNA that contain the code for specific proteins are called genes.
Actual coding region of DNA are called exons.
Explanation:
A segment of DNA that codes for one distinct protein is called a gene. Each chromosome carries thousands of various genes. The genetic code of the DNA ever prevails protected inside the nucleus.
a gene is a stretch of DNA. Nucleotide consists of a sugar, phosphate and a base.. Genes are organized and packaged in units named “chromosomes.” Humans have 23 pairs of chromosomes.
They both are formed through the attraction of atoms possessing opposite polarities. Hydrogen bonds is a relatively weak bond between two oppositely charged sides of two or more molecules and in an ionic bond, an atom gives away one or more electrons to another atom, which means the ionic bond is stronger.
Answer;
B. the cell was unable to maintain a stable internal environment.
Explanation;
-A sodium ion imbalance could cause water to rush across the cell plasma membrane in either direction. Too little water makes the cell shrivel up; too much water makes it burst. The balance between water and electrolytes, such as sodium ions, controls cell integrity.
-Electrolytes are molecules that influence cell fluid regulation. Sodium is the most abundant electrolyte. Too much sodium in the surrounding fluid - or too little in the cells - sucks too much water out of the cells.
-Too little sodium in the surrounding fluid - or too much within the cells -causes cells to swell as their higher sodium concentration draws too much water in, which eventually causes cell and organelle membranes to burst.
