What statement is correct regarding the cells and DNA?
all the cells have identical DNA
What is Major enzyme involved in replication?
DNA polymerase
What are the 3 major groups of chemicals in DNA?
What are the 3 major groups of chemicals in DNA? DNA is made up of three basic chemical components: Phosphate. Deoxyribose (a sugar). Two Pyrimidines Cytosine and Thymine. Two Purines Guanine and Adenine.
How does transcription differ from DNA replication Describe at least four differences?
DNA replication produces a complimentary DNA strand. Transcription produces a complimentary mRNA strand. The major enzyme that carries out DNA replication is DNA Polymerase III (in prokaryotes). The major enzyme that carries out transcription is RNA Polymerase. DNA replication results in two copies of the DNA. Transciption does not affect the DNA - it simply re-anneals (re-joins) after the process. In DNA replication the complementary base to A is T. In transcription the complementary base to A is U.
Which attractive force is a major factor in the formation of DNA?
Hydrogen bonds
Do CSI find DNA?
Yes - crime scene investigators can find DNA. If there is blood, hair, skin, etc. they can obtain DNA. This can then be tested against suspects (or databases).
What statement is correct regarding the cells and DNA?
all the cells have identical DNA
How does DNA help in solving crime?
DNA found at a crime scene can be compared to DNA samples from suspects or a DNA database to identify potential perpetrators. The unique sequence of DNA acts as a genetic fingerprint, providing strong evidence to link individuals to the scene of a crime. DNA analysis has become a powerful tool in both exonerating innocent individuals and convicting guilty ones.
What are DNA strands separated by?
Assuming this is regarding DNA replication or transcription, the enzyme helicase separates the two strands.
What has the author James T Durian written?
James T. Durian has written: 'The evolution of carrying concealed weapons - CCW - policies in Michigan' -- subject- s -: Firearms, Law and legislation, Weapons 'Forensic DNA databases' -- subject- s -: DNA fingerprinting, Databases, Forensic genetics, Law and legislation
What major enzyme involved on replication?
DNA Helicase is the major enzyme involved in the replication of DNA. The reason why it is so important is that it unwinds the DNA which creates two separate strands.
Can DNA be thought of as a database if yes why so and if not then why not?
Yes, you can carefully use it as an analogy. DNA does store information that is accessible to the cell machinery, but when you combine or fuse to databases, you don't generate different information.
What are the three forensic databases?
The three main forensic databases are CODIS (Combined DNA Index System), AFIS (Automated Fingerprint Identification System), and IAFIS (Integrated Automated Fingerprint Identification System). These databases are used by law enforcement agencies to store and match DNA profiles and fingerprints from crime scenes and individuals.
What is the major compound in DNA?
DNA is a compound known as deoxyribonucleic acid.
What important piece of information did Rosalind's work add to the puzzle regarding the structure of the DNA molecule?
Her studies of DNA with X-ray diffraction indicated that DNA is a double helix.
What major chemical molecule compose chromosomes?
i think that the answer is DNA i think that the answer is DNA
What is the major subunit of DNA called?
DNA's sub unit is called a nucleotide.
