The specific application involved in reverse transcriptase preparation of cDNA is a synthesis of DNA to form an RNA-DNA duplex.

What is reverse trancriptase activirt in cDNA?

  • Recombinant RNA-dependent DNA polymerases known as reverse transcriptases are employed in molecular biology to catalyze the conversion of RNA into DNA during a first-strand cDNA synthesis reaction.
  • A double helix molecule with an RNA-DNA hybrid is created by this process. When an RNA fragment is complexed with DNA, reverse transcriptases feature an RNase H domain with endoribonuclease activity that specifically breaks down RNA.
  • The RNA fragment can only be transcribed once thanks to the degradation of RNA in an RNA-DNA complex, which minimizes transcription bias and ensures reaction fidelity.

Reverse transcriptases from either the avian myeloblastosis virus (AMV) or the Moloney murine leukaemia virus (MMLV) are used in the majority of commercial reverse transcription kits.

Compared to AMV, MMLV provides a number of benefits, but its reduced error rate and greater processivity rate stand out.

Hence, the correct answer is a synthesis of DNA to form an RNA-DNA duplex.

Match the gastric phase on the left (1-3) with the correct description on the right (4-6):
dem82 [27]

Answer:

1 and 5,

2 and 6,

3 and 4

Explanation:

Intestinal phase: stomach empties and decreases secretions

The intestinal phase is the phase where stomach empties its contents(chyme) and decreases secretion. In this stage the duodenum responds to arriving chyme and moderates gastric activity through hormones and nervous reflexes.

The Chyme is the semi-fluid mass of partly digested food that is expelled by the stomach, through the pyloric valve, into the duodenum.

Gastric phase: stomach secretes juice and mixes food into chyme

The gastric phase is a period in which swallowed food and semi-digested protein ( peptides and amino acids ) activate gastric activity  which secretes juice and mixes food into chyme. About two-thirds of gastric secretion occurs during this phase.

Cephalic phase: prepares stomach for arrival of food

The cephalic phase of digestion is the gastric secretion that occurs prior to when food enters the oral cavity. Cephalic phase result from the ignition of  visual, olfactory, and auditory inputs to the brain and also induce anticipatory responses i.e  prepare the gastrointestinal tract for the meal.

In cells where telomerase is normally inactive, it can become active by accident and often, cancer will develop as a result. Can
vesna_86 [32]

Answer:

Cancer cells achieve proliferative immortality by activating or upregulating the normally silent human TERT gene (hTERT) that encodes telomerase, a protein with reverse transcriptase activity that complexes with other proteins and a functional RNA (encoded by hTR, also called hTERC) to make a ribonucleoprotein enzyme.

Explanation:

A rare cell that escapes crisis almost universally does so by reactivating telomerase and this cell can now become a cancer cell with limitless potential to divide. Almost all cancer cells have short telomeres and thus inhibitors of telomerase should drive such cancer cells into apoptotic cell death. Yet, each time a cell divides, the telomeres get shorter. When they get too short, the cell no longer can divide and becomes inactive or "senescent" or dies. This process is associated with aging, cancer, and a higher risk of death.
