Question

Determine if the following statements are true or false. 1. Most bacterial species contain linear chromosomal DNA. 2. A typical bacterial chromosome is a few million base pairs in length. 3. Most bacterial species contain a single type of chromosome, but it may be present in multiple copies. 4. The short regions between adjacent bacterial genes are called repetitive sequences. 5. Bacterial chromosomes have multiple origins of replication.

Answer 1

Answer:

1. Most bacterial species contain linear chromosomal DNA :

false

2. A typical bacterial chromosome is a few million base pairs in length :

true

3. Most bacterial species contain a single type of chromosome, but it may be present in multiple copies :  true

4. The short regions between adjacent bacterial genes are called repetitive sequences.: false

5. Bacterial chromosomes have multiple origins of replication : false

Explanation:

1) Most of the bacterial species doesn't contain linear chromosomal DNA , they contain single circular DNA molecule of loosely organized DNA.

2) A typical bacterial chromosome is a few million base pairs in length is a true statement

3) Most bacterial species contain a single type of chromosome, but it may be present in multiple copies is also true statement.

4) The short regions between adjacent bacterial genes are not called repetitive sequences.

5)  Bacterial chromosomes don't have multiple origins of replication , they replicate by binary fission.
