7 0
Answer: A( adenine) G (Guanine) C (Cytosine) T (Thymine) U (Uracil)

Why? Nucleic acids are polynucleotides—that is, long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. ... Each nucleic acid contains four of five possible nitrogen-containing bases: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U).

A student made a model of a cell. First, she filled a clear plastic bag with gelatin.
Ksivusya [100]
B) the model does not show that cells can contain smaller structures inside.

This is true because only a rubber ball was added, indicating that only a nucleus or any one organelle is present in a cell. However, the cell contains more than one organelle from the nucleus, mitochondria, Golgi apparatus, smooth and rough endoplasmic reticulum, ribosomes, and more.

Another possible answer would be D since they model does not show the process of cellular respiration where cells undergo this process to create ATP in the mitochondria.

Hershey and Chase used radioactive isotopes to label different parts of the phage. They grew one batch of phage in the presence
AlekseyPX

The sulphur would lable the capsule and the phosphorous the nucleic acid.

<h3><u>Explanation</u>:</h3>

Hershey and Chase experiment included growing of the pages in two batches, one in presence of 35S and other in presence of 32P. They then infected bacterial cells with these phages, cleaned them and then centrifuge the cells to isolate the marked elements in bacterial cells.

This was done to isolate which part of the phage is actually infective. Sulphur being a part of the proteins will mark the capsule whereas DNA having the phosphate bridges will be marked by 32P.
