What else can I help you with?
An okazaki fragment has which of the following arrangements?
An Okazaki fragment is a short, newly synthesized DNA fragment that is formed on the lagging strand during DNA replication. It is composed of a short RNA primer at the 5' end and DNA nucleotides that extend toward the replication fork.
What is true of the DNA fragment band closest to the positive end of the gel?
they are the smallest.
The sequence of a DNA fragment can be determined by observing the order of the fluorescent bands on the electrophoresis gel?
Yes, the sequence of a DNA fragment can be determined by the order of the fluorescent bands on the electrophoresis gel, which corresponds to the sequence of the nucleotides in the fragment. Each fluorescent band represents a different nucleotide in the DNA sequence. By comparing the band pattern to a known sequence ladder, the sequence of the DNA fragment can be read.
A dna fragment with a sticky end that reads -attcg will bind with another dna fragment with a sticky end that reads?
ATTCG signify adenine (A), thymine (T), cytosine (C) and guanine (G). The bonding pairs are AT, GC when DNA replicates. Therefore the fragment ATTCG will bind to TAAGC.
Organisms or fragments of DNA that are genetically identical to the organism or fragment they were produced from are called?
D. Enzymes
How many bases of DNA are in 1 kilobase fragment?
There are 1000 bases of DNA in a 1 kilobase fragment.

What is a vector used for in a genetic engineering experiment?
"Vector" is an agent that can carry a DNA fragment into a host cell. If it is used for reproducing the DNA fragment, it is called a "cloning vector". If it is used for expressing certain gene in the DNA fragment, it is called an "expression vector".
Is genetic egineering the insertion of a small fragment of frog DNA into the DNA of another species?
Genetic engineering
What is true of the DNA fragment band closest to the positive end of the gel?
they are the smallest.
What is semidiscontinuous DNA means?
Semidiscontinuous DNA is a lagging strand synthesis. It is a short fragment in the structure of double helix.

What general shape does this fragment of DNA resemble?
The DNA molecules resembles a twisted step ladder
Why might a laboratory be using dideoxy nucleotides?
A laboratory might be using dideoxy nucleotides in DNA sequencing reactions, specifically in the Sanger method. Dideoxy nucleotides lack a 3’ hydroxyl group needed for DNA chain elongation, resulting in termination of DNA synthesis at specific bases. This allows for the determination of the nucleotide sequence of a DNA fragment.
How can the amazon be the world's biggest river but not the longest river?
Its the worlds biggest because of the volume of water carried. It is not the longest.
What type of enzyme is used to fragment dna?
Restriction enzymes are used to fragment DNA by cutting it at specific recognition sites. These enzymes are naturally found in bacteria as a defense mechanism against foreign DNA, and are commonly used in molecular biology techniques like restriction enzyme digestion.
