What are the key differences between a bacterial artificial chromosome and a plasmid in terms of their structure and functionality?
Bacterial artificial chromosomes (BACs) are larger and can hold more DNA than plasmids. BACs have specific sequences for replication and stability, making them more reliable for cloning large DNA fragments. Plasmids are smaller and have fewer features for DNA manipulation. They are commonly used for smaller DNA inserts and gene expression studies.
What else can I help you with?
Is Bacterial Artificial Chromosome DNA low copy or high copy?
Bacterial Artificial Chromosome (BAC) DNA is typically considered low copy. This means that BAC vectors usually exist as single or a few copies in a bacterial cell, making them suitable for maintaining large DNA inserts without the risk of amplification errors.
A typical bacterial chromosome has 4.6 million nucleotides this supports how many genes?
The number of genes in a bacterial chromosome can vary depending on the size of the genes and the presence of non-coding regions. On average, a bacterial chromosome of 4.6 million nucleotides may contain around 4,000 to 5,000 genes.
What are the key differences between bacterial DNA and human DNA?
Bacterial DNA is typically circular and found in a single chromosome, while human DNA is linear and organized into multiple chromosomes. Bacterial DNA is also smaller and contains fewer genes compared to human DNA. Additionally, bacterial DNA lacks introns, which are non-coding regions found in human DNA.
The DNA-containing region of this bacterial cell is indicated by the letter?
The DNA-containing region of a bacterial cell is indicated by the letter "C", where the bacterial chromosome is located.
Circular DNA molecule that is not part of the chromosome in bacterial cells?
The circular DNA molecule that is not part of the bacterial chromosome is called a plasmid. Plasmids are small, extrachromosomal pieces of DNA that can replicate independently of the bacterial chromosome. They often carry genes that provide bacteria with additional functions, such as antibiotic resistance.

What are BACs and YACs?
BAC = Bacterial Artificial Chromosome -200-300Kb -good for genomic libraries -uses the bacterial F (sex) plasmid -currently quite popular YAC = Yeast Artificial Chromosome -1Mb -good for genomic libraries also -difficult to manipulate and use -less popular
What does the bacterial cell reproduce that the human gene codes for?
the bacterial cell reproduces the bacterial chromosome that the human gene codes for.
Do bacterial cells have a nuclues?
Bacterial cells are not eukaryotic cells, which means they do not have a nucleus. They do, however, have chromosome.
How are prophages and bacterial plasmids similar?
Prophages and bacterial plasmids are both genetic elements found in bacteria. They can replicate independently from the bacterial chromosome and confer certain traits to the bacterial host, such as antibiotic resistance. Additionally, both prophages and plasmids can integrate into the bacterial chromosome and be vertically inherited during cell division.

What are two types of vector used in recombinant DNA technology?
there are many different vectores as: 1-plasmid system 2-bacteria phage lamda 3-cosmids 4-bacterio artificial system 5-puc system the other cloning vectors are m13 which is the oldest one. and after the above all are:- BAC(bacterial artificial chromosome) YAC(yeat artificial chromosome) TAC(transformation-competent artificial chromosome)

They often carry genes that provide bacteria with additional functions, such as antibiotic resistance.
What enzyme is coded forin the chromosome of bacteria?
One common enzyme coded for in the chromosome of bacteria is DNA polymerase, which is responsible for replicating the bacterial DNA during cell division. This enzyme is essential for maintaining the integrity of the bacterial genome.
When the bacteriophage DNA becomes part of the bacterial chromosome?
When bacteriophage DNA becomes integrated into the bacterial chromosome, it is known as lysogeny. The integrated phage DNA is called a prophage. During lysogeny, the bacteriophage DNA remains dormant, replicating along with the bacterial chromosome. Under certain conditions, such as stress, the prophage can become activated and enter the lytic cycle, leading to viral replication and cell lysis.
