A tuberculin skin test  is done to see if the patient has ever been exposed to the bacteria that causes tuberculosis (Mycobacterium tuberculosis). The test is done by putting a small amount of antigens of the bacteria under the skin.
 If the patient was exposed, there will be a firm red bump where the antigens were placed but it would take 2 days to see the results so the patient needs to come back again after that time.

explain the basic process of DNA synthesis (including the distinction between lagging strand and leading strand synthesis) and u
Arada [10]

Answer:

Please the explanation below

Explanation:

DNA synthesis occur at the S phase of the cell cycle in preparation for cell division. The process which is also known as DNA replication occur in 3 main stages namely:

  • Initiation
  • Elongation
  • Termination

At the initiation stage, the double helix DNA structure is unwound by DNA helicase enzyme to form a Y shape structure known as the replication fork. A short pieces of RNA called primer then binds to 3' end of the DNA strands at the starting point of replication.

During elongation, an enzyme known as DNA polymerase adds bases to the primer in the 5' to 3' direction. This makes the replication of the leading strand to be continuous. RNA primer binds to the lagging strand at multiple regions and are replicated in short disjointed fragments known as okazaki fragments. This kind of replication is discontinuous.

Termination involves the unbinding of RNA primer by an exonuclease enzyme. The primers are then replaced by relevant bases. Proofreading of the newly synthesized strands takes place and the okazaki fragments are joined together by an enzyme known as DNA ligase. Telomerase enzyme then adds telomeres to the end of the DNA strands and each newly synthesized strand winds to its parent strand.

can someone explain the following and give examples: protons nuetrons and electrons there charges etc.(for 30 points)​
alexdok [17]

Explanation:

Protons are positively charged sub-atomic particles that are in the nucleus of an atom and have a relative mass of 1. Neutrons have a neutral charge, meaning they have no charge, and are also in the nucleus of an atom with a relative mass of 1.Electrons are negatively charged particles that orbit the nucleus in electron clouds. They are said to have a relative mass of 0.

For example, a sodium atom is number 11 on the periodic table. The atomic number of sodium tells us the no. of protons contained within its nucleus as well as the number of electrons orbiting. So we can say that sodiun has 11 electrons and 11 protons. To determine the number of neutrons, simply subtract the number of protons from the mass number( found on periodic table)

23-11=12 neutrons

NEED HELP ASAP!!!!!! Jade creates a Punnett square to show the cross between a parent with freckles and a parent without freckle
melomori [17]

Answer:: Jade's error occurs in the top-right square of the Punnett square. In this square, she identifies the phenotype as freckles, but to have freckles, the offspring must have at least one dominant allele. The offspring in this box are ff. Because there is no dominant allele present, the offspring will not have freckles.
