Can DNA fragments from human and bacteria be joined?

Yes, DNA fragments from humans and bacteria can be joined together using techniques such as molecular cloning. This process involves inserting a DNA fragment from one source into a vector, such as a plasmid, and then introducing the vector into a host organism to replicate the combined DNA.


Does DNA synthesize in bacteria?

Yes, DNA synthesis occurs in bacteria as part of their replication process. Bacteria replicate their DNA prior to cell division to ensure that each daughter cell receives a complete set of genetic material. This process involves the duplication of the bacterial genome by enzymes such as DNA polymerase.


Is there free floating DNA in bacteria?

Yes, bacteria can have free-floating DNA in their cytoplasm, which can exist as plasmids or fragments of chromosomal DNA. This free DNA can play a role in gene regulation and horizontal gene transfer, allowing bacteria to acquire new traits, such as antibiotic resistance. Unlike eukaryotic cells, bacterial DNA is not enclosed within a nucleus, facilitating its accessibility and interaction within the cell.


What is recombination DNA?

== == DNA fragments cannot function all by themselves. They must become part of the genetic material of living cells before the gene they contain can be activated. In the second step of genetic engineering, DNA fragments are made into part of the recipient cell's genetic material. This is done by combining DNA fragments with DNA from the recipient cell. For example, DNA fragments may be combined with bacterial DNA so that they can later be inserted into a bacterial cell. Bacteria often contain small circular DNA molecules known as plasmids in addition to their chromosomes. These plasmids can be removed from bacterial cells and cut with the same restriction enzyme used to produce the DNA fragments. The cuts made by the restriction enzyme produce matching "sticky ends" on the DNA fragments and the cut plasmids. These sticky ends are the sites at which a DNA fragment and a plasmid can be joined end to end, thereby forming a new plasmid that contains a piece of foreign DNA. The combined DNA formed by fusing a DNA fragment and a plasmid consists of parts from different kinds of organisms. In genetic engineering, molecules of combined DNA are known as chimeras because they are produced by combining DNA from different species. Combined DNA is also known as recombinant DNA, since DNA from two sources has been recombined to produce it.


What does the charge of DNA have to do with DNA fingerprinting?

DNA is of a negative charge. So when gel electrophoresis is used on it the DNA fragments are attracted to the positive end of the electrophoresis. The fragments of different lengths travel down the gel towards this end. The longer length fragments travel less and so are farther from the positive end. By looking at these DNA fragments, which are created by cutting DNA with restriction enzymes one can compare and contrast DNA. Thus DNA fingerprinting can take place based on the different restriction sites in DNA (cut by the enzymes) forming different length segments of DNA.

Which best describes transformation in bacteri?

Bacteria can undergo transformation, a process where they take up genetic material from their surroundings, such as fragments of DNA from other bacteria. This acquired DNA can then be incorporated into the bacterium's own genome, potentially leading to genetic variation and adaptation to new environmental conditions.


The DNA fragments making up a genomic library are generally contained where?

The DNA fragments making up a genomic library are generally contained within bacterial or viral vectors, such as plasmids or bacteriophages. These vectors are used to transform host cells, where the DNA fragments can be replicated and stored as part of the library.

How do you get DNA fragments in Bakugan dimensions?

You get DNA fragments by entering Bakugan codes.


What is the process of adding fragments of DNA to other DNA called?

The process of adding fragments of DNA to other DNA is called DNA ligation. This involves joining together two DNA fragments using an enzyme called DNA ligase, which helps to form a covalent bond between the DNA fragments.


What is the function of a DNA ladder in gel electrophoresis and how does it aid in the analysis of DNA fragments?

In gel electrophoresis, a DNA ladder serves as a reference for determining the sizes of DNA fragments being analyzed. It contains DNA fragments of known sizes, which help in estimating the sizes of unknown DNA fragments by comparison. This aids in accurately identifying and analyzing the DNA fragments present in the sample.

How does agarose gel electrophoresis work to separate DNA fragments based on their size?

Agarose gel electrophoresis separates DNA fragments based on their size by using an electric current to move the fragments through a gel made of agarose, a substance derived from seaweed. Smaller DNA fragments move faster through the gel, while larger fragments move more slowly. This separation occurs because the gel acts as a sieve, with smaller fragments able to navigate through the pores more easily than larger fragments. As a result, the DNA fragments are separated into distinct bands based on their size when viewed under ultraviolet light.

What are DNA fragments that have attached RNA fragments called?

Okazaki fragments.


What are the fragments making up the noncontinuous strand called?

The fragments making up the noncontinuous strand in DNA replication are called Okazaki fragments. These are short DNA fragments that are synthesized discontinuously on the lagging strand during DNA replication.
