A food that contains only 7 amino acids is?
Nonamiya [84]

Answer and Explanation:

Certain foods that are incomplete proteins do not contain all of the necessary amino acids that would be helpful.

Incomplete protein foods are anywhere from seeds, nuts, and whole grains. Whole grains consist of whole wheat bread and brown rice. Not only that, but even types of beans, peas and lentils (which tend to be part of the legume family).

Typically, incomplete proteins are harder for the body to digest and brake down. But don't be fooled, not all complete proteins are easy to be broken down either.

If you have any more questions, let me know. I hope this helps.

makkiz [27]

Answer:

The correct answer will be-

1. Nucleosomes

2. Chromatin

3. Sister chroamtid

4. Centromere

Explanation:

The DNA is a very long molecule which if has to be passed on to the daughter cell as it is will cause problems. So, to reduce problems a cell form tightly packed structure of DNA so that they can be passed easily to the daughter cell.

The packaging of DNA begins with the wrapping of the DNA around histone proteins which forms the 11 nm basic structural units called nucleosomes. The nucleosomes start condensing each other and form 30 nm structure chromatin fibres.

The chromatin fibres undergo replication during S phase which produces an exact copy of the chromatin called sister chromatids bound to each other at a central point called centromere which helps the separation of the chromatids during M phase.
