What structures in cells contain DNA and proteins?

Biology
1 answer:
iren2701 [21]4 years ago
4 0

The structure in cells that contains  DNA and protein is the nucleosome, found in the nucleus.  In the nucleus of the cell, DNA is exists in the form of a long helical thread. It order to fit inside the nucleus, the DNA thread must be compressed enough to do so.

The cell accomplishes this by wrapping the DNA thread around a protein called histone. A single unit of DNA and histone octamer (called octamer because it consists of 8 proteins) is called a nucleosome.

The entire stretch of DNA in an average human cell is about 2 meters in length and would never fit inside a cell if not for histone proteins.

Andrei [34K]

Answer:

Her Thinking is wrong because ATP is not a long term Energy Storage.

Explanation:

We need energy to perform every single task of everyday life. This energy is obtained from the food we eat. There are three main sources of energy in our food.

1. Carbohydrates

2. Lipids

3. Proteins

Carbohydrates are hydrolyzed into glucose upon breakdown and this glucose  is used as energy by most of the cells. While Lipids are more complex molecules and usually used to store energy to be used later. Proteins help in muscle building and provide essential amino acid to the body.

There are two ways to store energy, Long term storage and short term storage. The ATP is obtained by breaking down the large molecules and considered as short term energy as it last for only few seconds. While the long term energy is obtained from lipids hydrolysis.
