The restriction enzyme used in constructing hybrid molecules of certain gene sequences and plasmid DNA acts by?
recognizing specific DNA sequences (restriction sites) on both the gene sequence and plasmid DNA, and cutting the DNA at these sites. This creates compatible ends that can be ligated together to form a hybrid molecule. The enzyme ensures precise, targeted manipulation of DNA sequences in genetic engineering applications.
What advantages do bacteria offer biotechnologist?
Bacteria are used by biotechnologists for their rapid growth rate, which allows for quick and easy production of proteins and other molecules. They are also highly versatile and can be genetically manipulated to produce desired substances. Additionally, bacteria are cost-effective to work with in the laboratory.
What is difference between DNA probe and primer?
A DNA probe is a single-stranded DNA sequence used to detect complementary sequences, whereas a primer is a short single-stranded DNA sequence used to initiate DNA synthesis during PCR. Probes are used to identify specific sequences in a sample, while primers are used to amplify a specific target sequence.
What is the name of the substance that is used to cut DNA at particular sequences?
DNA is cut by a special kind of enzymes called restriction enzymes.
Why was the discovery of restriction enzymes important to recombinant DNA technology?
Recombinant DNA technology requires fragments of DNA from the source genome. Using crude methods such as mechanical shearing, we get random fragments of DNA, and their sequence is unknown. Restriction enzymes are specific in site recognition and cutting and their discovery lead to proper fragments of DNA which have some known sequences.

What are radioactive probes?
Radioactive probes are molecules that are labeled with a radioactive isotope, such as ^32P or ^35S, which emit radiation that can be detected. They are commonly used in molecular biology to detect specific DNA, RNA, or protein molecules by binding to complementary sequences and producing a signal that can be visualized.
Enzymes used to cut DNA molecules in recombinant DNA researsh are?
Restriction enzymes are used to cut DNA molecules in recombinant DNA research. These enzymes recognize specific DNA sequences and cleave the DNA at those sites, allowing scientists to splice DNA fragments from different sources together to create recombinant DNA molecules.

What is blotting and types of blotting?
Blotting is a technique of transferring DNA or RNA or Protein from a gel to the membrane. nitrocellulose, PVDF or nylon membrane are used to attach these molecules permanently on them. Western, southern and norther blotting are the techniques used to transfer protein, DNA and RNA respectively. It is done to detect them with a specific probe or antibody. This can not be detected or easy to handle on the gel, so we do blot for these analysis.
What are three types of molecular data that can be used to build phylogenies?
Three types of molecular data commonly used to build phylogenies are DNA sequences, RNA sequences, and protein sequences. DNA sequences provide insights into genetic relationships and evolutionary history through comparisons of specific genes or whole genomes. RNA sequences, particularly ribosomal RNA, are often used to understand evolutionary relationships among diverse organisms. Protein sequences can reveal functional similarities and differences, helping to infer phylogenetic relationships based on evolutionary changes in amino acid sequences.
Which of the following can be used to cut DNA so it can be studied?
Restriction enzymes are commonly used to cut DNA at specific sequences, creating fragments that can be studied. These enzymes recognize and cut at specific nucleotide sequences, allowing for precise manipulation of DNA for further analysis.
Why are palindromes important to genetic engineers?
Palindromes are important to genetic engineers because they are sequences of DNA that read the same forwards and backwards. These sequences are used in genetic engineering to help identify specific regions of DNA for manipulation and study. By recognizing palindromic sequences, genetic engineers can target and modify specific genes more accurately and efficiently.

Molecules that seek out and identify a particular molecule or piece of DNA are referred to as?
Molecules that seek out and identify a particular molecule or piece of DNA are referred to as probes. These probes are commonly used in molecular biology research to detect specific sequences of DNA or RNA. They can be labeled with fluorescent or radioactive markers for visualization.
