V125BC [204]3 years ago
5 0
The corresponding sequence in the RNA transcript is 5'-UACGACUG-3' . One of the differences between DNA and RNA is the fact that the RNA contains the base uracil instead of thyamine. The base pairing occurs between A and T, and G and C. DNA undergoes the process of transcription in the nucleus to generate RNA, which then undergoes translation (for mRNA) in the cytoplasm to yield proteins.

The client has had asymptomatic sinus bradycardia with a rate of 56 beats/min. the nurse notes the rate has dropped to 46 beats/
lisabon 2012 [21]
I think the nurse should asses the blood pressure, skin color, and moisture. Sinus bradycardia may be defined as a sinus rhythm with resting heart rate of 60 beats per minute or less. However few patients become symptomatic until their heart rate drops to less than 50 beats per minute. Intervention for sinuses bradycardia should be based on assessment of the clients condition. The patient may remain asymptomatic, the nurse may choose to increase the IV flow rate, administer atropine, or notify the Rapid Response Team depending on the severity of the symptoms.

Apoptosis involves all but which of the following?
LenaWriter [7]

Answer:

Apoptosis does not involve:

c. lysis of the cell

Explanation:

Apoptosis is a programmed cell death that occurs under normal physiological conditions and in a controlled manner. Normally seen in cell turnover, embryogenesis, also involved in processes of immune, nervous and endocrine systems.

The main morphological and biochemical changes seen during the apoptosis are the fragmentation of DNA by endonucleases, nuclear, chromatin and cytoplasmatic condensation, apoptotic bodies formation (membrane bound-vesicles form of cell parts) and the phagocytosis (digestion) of those bodies by the scavenger cells.

Apoptosis is regulated by cell- signaling pathways, the caspases, a family of cysteine proteases, are the ones involved in the process.

In the process there is no lysis of the cell as this could lead to a inflammatory response (just happens in necrosis) which would affect contiguous cells, and will involve immune cells. In apoptosis there is just a membrane blebbing, but it does not loss its integrity.

Duplication of chromosomes occurs during S phase of the cell cycle. Duplication requires the separation of complementary DNA str
frozen [14]

Answer:

Some statements of the question are missing but it can be understand as the Hydrogen bonds are Easy to break, Less amount of heat required, Less amount of enzyme needed and Can be broken by mild concentration of enzyme.

Explanation:

Weak bonds like hydrogen bonds are found to beneficial in some situations. During the duplication of chromosomes which occurs in S phase of cell cycle the DNA replicated. This replication is facilitated by separation of the two strands of DNA and formation of complimentary strand on the two primary strands. The enzymes involved in the process of separation of strands are DNA helicase and Topoisomerase mainly. As the bonds between the strands are weak hydrogen bonds, the enzymes function effectively without requiring extra heat or more saturation. It will found to be difficult if those bonds will be covalent bonds because they are much stronger than hydrogen bonds and are not easily broken by these enzymes. Extra processes will be required to break those strong bonds.
