Chapter 10: Problem 1

What is a bacterial nucleoid? With regard to cellular membranes, what is the difference between a bacterial nucleoid and a eukaryotic nucleus?

Short Answer

Expert verified
A bacterial nucleoid contains the bacterial cell's genetic material and is not membrane bound, unlike a eukaryotic nucleus, which is surrounded by a nuclear membrane.

Step by step solution

01

Definition of bacterial nucleoid

A bacterial nucleoid is the part of a bacterial cell where the genetic material is located. It is not surrounded by a nuclear membrane, which differentiates it from the eukaryotic cell nucleus. It has a singular circular bacterial chromosome of double-stranded DNA.
02

Definition of Eukaryotic nucleus

The eukaryotic nucleus is a highly specialized organelle that serves as the information and administrative center of the cell. This organelle has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Unlike the nucleoid, it is surrounded by a nuclear membrane.
03

Comparison of bacterial nucleoid and Eukaryotic nucleus in terms of cellular membranes

The primary difference between a bacterial nucleoid and a eukaryotic nucleus, in terms of cellular membranes, is that the bacterial nucleoid is not bound by a membrane, while the eukaryotic nucleus is surrounded by a double membrane, known as the nuclear envelope. This nuclear envelope separates the nucleus contents from the cellular cytoplasm.

How are two topoisomers different from each other? How are they the same?

Take two pieces of string that are approximately 10 inches long, and create a double helix by wrapping them around each other to make 10 complete turns. Tape one end of the strings to a table, and now twist the strings three times \(\left(360^{\circ}\right.\) each time) in a righthanded direction. Note: As you are looking down at the strings from above, a right-handed twist is in the clockwise direction. A. Did the three turns create more or fewer turns in your double helix? How many turns does your double helix have after you twisted it? B. Is your double helix right-handed or left-handed? Explain your answer. C. Did the three turns create any supercoils? D. If you had coated your double helix with rubber cement and allowed the cement to dry before making the three additional right-handed turns, would the rubber cement make it more or less likely for the three turns to create supercoiling? Would a pair of cemented strings be more or less like a real DNA double helix than an uncemented pair of strings? Explain your answer.

Which of the following terms should not be used to describe a Barr body? A. Chromatin B. Euchromatin C. Heterochromatin D. Chromosome E. Genome

Coumarins and quinolones are two classes of drugs that inhibit bacterial growth by directly inhibiting DNA gyrase. Discuss two reasons why inhibiting DNA gyrase also inhibits bacterial growth.

Discuss the differences between the compaction levels of metaphase chromosomes and those of interphase chromosomes. When would you expect gene transcription and DNA replication to take place, during M phase or interphase? Explain why.
