Answer:

CODIS stands for Combined DNA Index Systems and is a computer program that stores the DNA Fingerprint of convicted criminals and missing persons. This program is very useful in forensic science.

Explanation:

CODIS is a computer program maintained by the FBI, which operates databases across the country. These databases contain more than five million profiles. CODIS covers several different indices.

CODIS uses algorithms to compare 13 different locations in STRs, plus one that determines the gender of the person in question. The system has rules and safeguards to protect the privacy of people in the database. Algorithms that point to positive results - which must be confirmed by an analyst - can provide clues to the police or even identify a possible criminal. The downside of using CODIS is that it only covers the profiles it includes - and there are over a million profiles waiting to be included in the system.

The Combined DNA Index System (CODIS) is the United States national DNA database created and maintained by the Federal Bureau of Investigation. CODIS consists of three levels of information; Local DNA Index Systems (LDIS) where DNA profiles originate, State DNA Index Systems (SDIS) which allows for laboratories within states to share information, and the National DNA Index System (NDIS) which allows states to compare DNA information with one another.

In the square of an element on the periodic table, the number with the highest numerical value represents the atomic number.

atomic number.

<h3>What is the atomic number Z?</h3>

The atomic number is represented by the letter Z and indicates the number of protons (p) in the nucleus of the atom. This quantity is characteristic of each chemical element.

With this information, we can conclude that The atomic number, represented by the capital letter Z, corresponds to the number of protons in the nucleus of atoms (Z = p).

The pap smear is ________ percent approximate in detecting cervical carcinoma

Katen [24]

Pap smear (Papanicolau smear) is a procedure that involves swabbing the endocervix (inner part of the cervix), ectocervix (outer part of the cervix), and the vaginal walls. This smear will then be fixed and then viewed through a microscope to check for atypical cells (or cancer cells). Pap smear has a 95% sensitivity so pap smear can detect cervical carcinoma 95% of the time.

Fluorescent in situ hybridization (Fish) is a method employing a fluorescent dye covalently bonded to a specific nucleic acid probe identifying or tracking organisms in the environment. Fluorescent in situ hybridization (fish) can be used to determine; how many salmonella typhimurium cells are present in a sample of unpasteurized apple juice, the phylogenetic diversity of an environmental sample and also whether a specific piece of mRNA is being produced.
