What is the relationship between the structure of nucleic acids and their charge?
The structure of nucleic acids, like DNA and RNA, is made up of negatively charged phosphate groups. This gives nucleic acids an overall negative charge.
How does an atom becomes Negatively charged?
An atom becomes negatively charged when it receives an electron from another atom. In other words, if there are more electrons than protons in an atom, it becomes negatively charged.
Why do bacteria tend to stain better with cationic dyes?
Bacteria have negatively charged cell walls, which attract cationic dyes that are positively charged. The interaction between the positively charged dye and the negatively charged cell wall enhances the staining process, making the bacteria more visible under a microscope.
Why are basic dyes more successful on bacteria than acidic dyes?
Basic dyes are positively charged and can easily bind to the negatively charged components of bacterial cells, such as the cell wall. This makes them more effective at staining bacteria. Acidic dyes, on the other hand, are negatively charged and repelled by the negatively charged bacterial cells, making them less successful for staining bacteria.
Why is the inside of the cell membrane negatively charged at resting potential?
The inside of the cell membrane is negatively charged at resting potential because of an unequal distribution of ions, specifically more negatively charged ions inside the cell compared to outside. This creates an electrical potential difference across the membrane, known as the resting membrane potential.
What is the net electrochemical charge of RNA?
RNA is a neutral molecule overall, meaning its net electrochemical charge is zero. This is because the negatively charged phosphate groups in the RNA backbone are balanced by the positively charged nitrogenous bases.
Will an object that is negatively charged what will it attract?
Negatively charged objects
Is lighting negatively charged or positively charged?
Negatively charge
Is an electron positively or negatively charged?
An electron is negatively charged.
Are cathodes positively or negatively charged?
Cathodes are negatively charged.
Are electron negatively charged atoms?
No. An electron is negatively charged but it is not an atom. It is a subatomic particle and the negatively charged component of an atom.
Which of the following particles is negatively charged?
An electron is negatively charged.
All compounds are negatively charged.?
No, all compounds are not negatively charged.
What can negatively charged objects?
Negatively charged objects can attract positively charged objects, repel other negatively charged objects, and cause static electricity buildup.
Is the nucleus of an atom negatively charges?
Firstly it's charged not charges. But no it is not negatively charged but positivly charged.
Are electrons positively charged or negatively?
Negatively charged
How are cathode charged?
negatively charged
