Chapter 1, Problem 7P
Summary Introduction
To determine: The cells that contain a gene for muscle phosphorylase enzyme.
Introduction. The catalysts that are present in the livings cells are called enzymes. The enzymes are protein molecules that may or may not be associated with other molecules like metal ions, vitamins, and so on. The enzymes increase the efficiency of the reaction and help to turn a large number of substrate molecules into products.

Mitosis is used to make more body cells while meiosis is only used to make gametes for sexual reproduction.
Use the diagram to identify one similarity and one difference between mitosis and meiosis. Your answer must
specifically refer to this diagram. [i.e. say what specific cells in the diagram show the similarity or difference]

The following diagram is meant to help you understand how the amount of DNA in a cell changes as the cell cycle progresses. On the diagram, identify two of the stages of the cell
cycle being described and identify how much DNA exists per cell, where a cell is defined as a distinct nucleus. Note that the sequence of images highlights one of the chromosomes
of the cell. The other chromosomes, while also present, are faded in the background.

Give the number of chromosomes and the number of DNA molecules per cell present at the stages represented. I tried to solve them, but I'm not sure what I did right and what was wrong. Please correct it for me. See that attached photo.arrow_forwardA cat has 38 total chromosomes (19 pairs). If one cell undergoes either mitosis or meiosis, identify the number of chromosomes and chromatids present in every phase of cell cycle.

Pairs 1 to 22 are autosomes, while pair 23 are the sex chromosomes. The pairs are described as homologous chromosomes.
