In an experimental situation, a student researcher inserts an mRNA molecule into a eukaryotic cell after he has removed its 5' c

ap and poly-A tail. Which of the following would you expect him to find?
(a)The mRNA could not exit the nucleus to be translated.
(b)The cell recognizes the absence of the tail and polyadenylates the mRNA.
(c)The molecule is digested by restriction enzymes in the nucleus.
(d)The molecule is digested by exonucleases since it is no longer protected at the 5' end.
(e)The molecule attaches to a ribosome and is translated, but more slowly.

fomenos

Answer:

The 3.9 billion year old rock has undergone three half-lives (3.9 divided by 1.3 = 3). After 3 half-lives, 12.5% of the potassium-40 remains undecayed.

central dogma. Central dogma is represented by the schematic above. All cells, whether prokaryotic or eukaryotic undergo this pr
o-na [289]
Central dogma is done by all cells which involves the process of DNA replication, transcription and translation. DNA replication involves making of a new DNA molecule  to copy the genetic information and takes place in the nucleus of a cell while Transcription is the formation of a mRNA from DNA molecule by RNA polymerase a process that takes place in the nucleus. Translation involves formation of polypeptides from the messenger RNA which takes place in the cytoplasm (cytosol) of both prokaryotic and eukaryotic cells in an organelle known as ribosomes.

Describe the chemical components of DNA.
Slav-nsk [51]

DNA is composed of nucleotides, which are composed of three parts:

1. A five carbon carbohydrate (pentose)

Pentose is classified as a monosaccharide (simple carbohydrate), and its molecular formula is represented by (CH_{2} O)n. They are water soluble molecules with sweet taste. Monosaccharides may have from three carbon atoms (trioses) to six (hexoses). In DNA is present pentose (5 carbon atoms)

2. A nitrogenous base

Nitrogenous bases are ring-shaped compounds that contain nitrogen in their molecular structure. They are classified into two groups: purines and pyrimidines

The purine bases are adenine (A) and guanine (G). They are larger and contain more than one ring in their structure,.

The pyrimidines, cytosine (C), uracil (U) and thymine (T), are smaller and composed of a single ring.

3. One or more phosphate groups

A phosphate consists of a trivalent anion that contains one phosphorus atom and four oxygen atoms. Its molecular formula is expressed by (PO_{4} ^{-3}).
