(B) The opposite is true, too - when genes from a goat are inserted into a spider's genome, the spider produces goats' milk instead of silk.
(C) The proteins in goats' milk and spiders' silk have the same amino acid sequence
(D)The processes of transcription and translation in the cells of spiders and goats are fundamentally similar.
(E)The processes of transcription and translation in the cells of spiders and goats produce exactly the same proteins anyway.
Answer:
(D)The processes of transcription and translation in the cells of spiders and goats are fundamentally similar.
Explanation:
The genetic information present in the spider DNA can be inserted, transcribed and translated using similar machineries to that present in spiders. This produces the same protein, but the protein is likely processed and exported differently, meaning it plays different roles in each organism.
This is true for lots of scenarios, scientists frequently insert human genes into mice, and even cells in culture!
Answer:
Option A
Explanation:
Complete question is
A client with a digoxin level of 2.4 ng/ml has a heart rate of 39. The health care provider prescribes atropine sulfate. Which of the following best describes the intended action of atropine for this client?
Select one:
a. To accelerate the heart rate by interfering with vagal impulses.
b. To reduce peristalsis and urinary bladder tone.
c. To dry oral and tracheobronchial secretions.
d. To stimulate the SA node and sympathetic fibers to increase the rate.
Solution -
Atropine improves the performance and output of cardiac system by inhibiting the action of vagal or parasympathetic. The rate of discharge from the sinus node (SN) increases and hence the chances of ventricular ectopy reduces.
This drug must be administered rapidly to prevent reflexes of bradycardia. The common dosage regime is 0.5 mg per 3 minutes in adults or as per the instructions of doctor.
Hence, option A is correct
The order of organisms that they would find in the layers of these sedimentary rocks is; Oldest organisms are at the bottom and the newest organism is in the top-most layer of the sedimentary rocks.
Sedimentary rocks are rocks that are made by the deposition and compression of other rocks or pieces of organic matter (dead plants and animals). According to the law of superposition which states that in a sequence of undisturbed sedimentary layers, the youngest layer is always at the top while the oldest layer is always at the bottom of the sequence. From the question, the organisms are components of the rocks. The oldest organisms will be found at the bottom layer of the sedimentary rocks while the newest organisms are in the topmost layer of the sedimentary rocks.
b. a-hemoglobin is present only in cells where B-hemoglobin is absent
c. a-hemoglobin mRNA is more stable than B-hemoglobin mRNA
d. Tubulin inhibits translation of hemoglobin mRNA
Answer:
Answer is A. B-hemoglobin mRNA is translated more efficiently than is a-hemoglobin mRNA.
Explanation:
The introduction of electric charge into a gel or fluid, causing or resulting in the movement of the charged particles in the gel or fluid, is referred to as the electrophoresis. It can also be explained as a separation method or technique which is based on the movement of particles or ions in an electric field.
The electrophoresis is used in separating DNA fragments , RNA or protein, based on their size and charge.
