What else can I help you with?
What is a reapeating unit of DNA that is made of 3 parts?
CODONS
3 main parts of a cell?
every cell has cytoplasm, a cell membrane, and DNA
Why can only parts of DNA be used as DNA fingerprint?
The parts must be unique to the person
What 3 parts make up the rungs of the DNA ladder?
The rungs of the DNA ladder are composed of alternating deoxyribose sugar molecules and phosphate groups.
Do all the nucleotides in human DNA belong to genes?
No - genes are the parts of DNA that code for a functional product (such as a protein). There are other parts of the DNA which are not genes.
Is DNA's substance sugar?
Part of DNA is a sugar! Each base unit of DNA, a nucleotide, consists of 3 parts: deoxyribose (a sugar), a phosphate (PO4-2), and a nucleoside, either adenosine, thymine, guanine, or cytosine.
Why can only certain parts of DNA be used as DNA fingerprinting?
The parts must be unique to the person.The parts must be unique to the person
What are the two parts of the backbone of DNA?
The two parts of the backbone of DNA are sugar and phosphate molecules. These molecules alternate in a pattern, forming the structure of the DNA double helix.
What 2 cell parts make DNA?
The nucleus and the mitochondria are the 2 cell parts that contain DNA. DNA is located in the nucleus of eukaryotic cells, while mitochondria have their own separate DNA known as mitochondrial DNA (mtDNA).
What are the 3 major parts of DNA replication?
The three major parts of DNA replication are initiation, where the DNA molecule unwinds and begins to replicate; elongation, where new DNA strands are synthesized by DNA polymerase; and termination, where replication is completed and two identical DNA molecules are produced.
What are the parts of DNA?
the parts of DNA are: phosphate nitrogenous base(adenine, guanine, thymine and cytosine) hydrogen band helical protein
What enzyme pastes the sticky ends of a DNA?
It is called DNA ligase. Catalyzes the formation of a phosphodiester bond between a 3'-hydroxyl group and a 5'-phosphate group in DNA. This enzyme catalyzes the joining together of two single-stranded DNA segments which may be either parts of the same duplex or parts of different duplexes. This enzyme functions in DNA replication and in DNA repair by linking DNa fragments together.In biotechnology, is widely used the DNA ligase from bacteriophage T4 that catalyzes the formation of a phosphodiester bond between adjacent 3'-OH and 5'-P termini in DNA.
