What is a collection of cells containing DNA fragments produced by restriction enzymes and incorporated into plasmids called?
A DNA LibraryA collection of cells containing DNA fragments produced by restriction enzymes and incorporated into plasmids is called a DNA library. RNA can manufacture DNA via the action of reverse transcriptase.
Describe how animal cells can be transformed by directly injecting DNA?
It is much like doing it with plant cells. You insert DNA into the egg cell. Then once in the cell the enzymes usually responsible for DNA repair help insert forein DNA into the chromosomes of the cells that have been injected.:)
What is restriction analysis?
Restriction analysis is a technique used in molecular biology to cut DNA at specific sites using restriction enzymes. This method allows researchers to manipulate and study DNA sequences by creating fragments of different lengths. The resulting DNA fragments can be separated and analyzed to determine the sequence and size of the original DNA.
Who were the other researchers to find the structure of DNA?
Luise
What scientist developed the technique of polymerase chain reaction?
The polymerase chain reaction (PCR) technique was developed by American biochemist Kary Mullis in 1983. This groundbreaking technique revolutionized molecular biology by allowing researchers to amplify DNA in vitro, making it a vital tool in various fields such as genetics, forensics, and medicine.
How does DAPI staining work to visualize DNA in cells?
DAPI staining works by binding to the DNA in cells and emitting a blue fluorescent signal when exposed to ultraviolet light. This allows researchers to visualize the DNA in the cells under a microscope.
How does DAPI stain work to visualize DNA in cells?
DAPI stain works by binding to the DNA in cells, causing it to emit a blue fluorescence when exposed to ultraviolet light. This allows researchers to visualize and study the DNA within the cells under a microscope.
What do you think researchers discovered in the mitochondrial DNA taken from the heart cells of older adults?
Researchers discovered that the mitochondrial DNA taken from heart cells of older adults showed more mutations and damage compared to younger individuals. This suggests that mitochondrial function deteriorates with age, which may contribute to age-related heart conditions.
A technique that can be used to compare the DNA of two or more plants is?
DNA sequencing is a technique that can be used to compare the DNA of two or more plants. By determining the sequence of nucleotides in the DNA of each plant, researchers can identify similarities and differences in the genetic code, allowing for comparisons and analysis of genetic variations between the plants.
What is a collection of cells containing DNA fragments produced by restriction enzymes and incorporated into plasmids called?
A DNA LibraryA collection of cells containing DNA fragments produced by restriction enzymes and incorporated into plasmids is called a DNA library. RNA can manufacture DNA via the action of reverse transcriptase.
What technique is used to amplify a DNA sample?
The technique used to amplify a DNA sample is called Polymerase Chain Reaction (PCR). PCR involves repeated cycles of denaturation, annealing, and extension, which allows for the exponential amplification of specific DNA sequences. This method is widely used in various fields, including genetics, forensics, and medical diagnostics. It enables researchers to generate millions of copies of a targeted DNA segment from a small initial sample.
Why would researchers use gel electrophoresis to study the DNA of moose and zebra?
Researchers use gel electrophoresis to study the DNA of moose and zebra to analyze genetic variations and relationships between species. This technique allows them to separate DNA fragments based on size, making it easier to identify specific genes or genetic markers. By comparing the banding patterns of DNA samples, researchers can gain insights into evolutionary biology, population genetics, and conservation efforts for these species. Additionally, it helps in understanding genetic diversity and potential adaptations to their environments.

What is hoechst?
Hoechst is a stain used in fluorescence microscopy to label DNA in cells. It emits blue fluorescence when bound to DNA, allowing researchers to visualize the nucleus and study the structure and organization of genetic material within the cell.
What explains the role of gel electrophoresis in forensic science?
Gel electrophoresis is used in forensic science to separate DNA fragments based on their size. It is a crucial technique for analyzing DNA evidence, such as identifying suspects or victims, matching samples, and determining genetic relationships. By running samples through a gel matrix under an electric field, researchers can visualize and compare DNA profiles for forensic investigations.
Is the DNA in prokaryotic cells circular or eukaryotic cells?
The DNA in prokaryotic cells is circular, while the DNA in eukaryotic cells is linear.
