What are the small segments synthesized in the lagging strand of DNA?
Okazaki fragments are the small DNA fragments synthesized on the lagging strand during DNA replication. They are later joined together by DNA ligase to form a continuous strand.
What way can DNA segments be changed such that genes are altered or mutated?
DNA segments can be changed through a variety of mechanisms, such as point mutations (single nucleotide changes), insertions or deletions of nucleotides, or rearrangements of DNA segments. These changes can alter the sequence of a gene, leading to a mutation that may affect the function or expression of the gene. Factors such as environmental exposures or errors during DNA replication can contribute to these changes.
Why are bacteria good for copying large amount of DNA?
They can reproduce very quickly
Short segments of newly synthesized DNA are joined into a continuous strand by?
ligase enzymes, which catalyze the formation of phosphodiester bonds between adjacent DNA fragments. This process is crucial for the completion of DNA replication and repair, as well as for the creation of recombinant DNA molecules in genetic engineering techniques.
Which best describes transduction in bacteria?
Bacteria transfer DNA with a bacteriophage.
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.
What are small circular segments of DNA often exchanged between bacteria?
Plasmid
How is a gene related to the sequence of nucleotides?
Genes are segments of DNA. DNA is made up of polymer of nucleotides joined together. When there is an alteration in the sequence of nucleotides, gene mutation occurs.

Which enzyme is responsible for connecting the short segments of newly synthesized DNA segments?
DNA polymerase

What is moving fragments from one organism and inserting them into another organism?
Changing an organism's DNA is called Genetic Engineering. An example is breaking segments of DNA plasmids from a glowing jellyfish off and fusing them with the DNA of a simple bacteria. The genetically modified bacteria reproduces and creates thousands of other bacteria that also glow under UV light. This colony of glowing bacteria are all now Genetically Engineered (And freaks)...

Are genes segments of DNA?
yes! :)
What molecules are needed to cut and copy segments of DNA?
To cut and copy segments of DNA, the primary molecules required are restriction enzymes and DNA ligase. Restriction enzymes recognize specific DNA sequences and cleave the DNA at those sites, allowing for the extraction of desired segments. DNA ligase then facilitates the joining of DNA fragments by forming phosphodiester bonds, effectively "gluing" the segments together. Additionally, DNA polymerase may be used for amplifying or synthesizing new DNA strands during the copying process.
The laboratory procedure for copying selected segments of DNA is?
The laboratory procedure for copying selected segments of DNA is called polymerase chain reaction (PCR). In PCR, the DNA template is heated to separate the DNA strands, then specific primers are added to initiate replication by a DNA polymerase enzyme. The process is repeated multiple times to amplify the DNA segments of interest.
