Continuous rotation of the CT x-ray tube and detector array, with simultaneous movement of the CT couch, has been accomplished t

Andrei [34K]

Answer:

The options

A. Additional cables

B. Slip rings

C. Multiple rows of detectors

D. Electron beam CT.

The CORRECT ANSWER IS B.

B. Slip rings

Explanation:

During the 1990s, the use of slip ring technology promoted consecutive rotation of the x-ray tube (via removal of cables) and concurrent couch locomotion.

The Sixth-generation CT scanning is referred to as helical (or spiral) CT—allowing procurement of volume multislice scanning.

Today's helical multislice scanners, makes use of thousands of detectors (around 60+ rows), can derive continuous data procurement of 128 "slices" per tube rotation and can undergo 3D multiplanar reformation (MPR).

Fifth-generation CT employs electron beam; as the ultra high-speed CT is employed majorly for cardiac imaging.

QUESTION 1 (5 marks) A molecule of messenger RNA (mRNA) has just been synthesized and processed in the nucleus of human cell wit

Dmitry [639]

1) DNA Template strand: TACAATCGACCCATC. 2) Anticodon: AAU. 3) mRNA carries genetic information to build the protein. 4) 5 amino acids. 5) Amino acids: Met, Leu, Ala, Gly, Tyr.

1)

<h3>What is the template strand?</h3>

When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments:

The coding strand that goes in 5' to 3' direction
The complementary strand -template strand- that grows in 3' to 5' direction .

The template strand is the one that is going to be complemented by the mRNA.

mRNA ⇒ AUGUUAGCUGGGUAG

DNA ⇒ TACAATCGACCCATC

Remember that pairs are as follows

T → A

A → U

G → C

2)

<h3>What is an anticodon?</h3>

The anticodon is the sequence of three nucleotides that couples with the mRNA codon.

Each tRNA has two important sites. One of them is the anticodon that couples with the codon of the mRNA molecule. The other one carries the amino acid that is going to be addeded to the protein.

1st 2nd 3th 4th 5th

mRNA codons ⇒ AUG UUA GCU GGG UAG

tRNA anticodon ⇒ AAU

3)

<h3>What is translation?</h3>

Translation is the stage of protein synthesis during which mRNA carries genetic information needed to synthesize the new protein in the cytoplasm.

Steps,

1- The formed mRNA moves to the cytoplasm through the nucleus membrane pores.

2- Once in the cytoplasm, mRNA meets a ribosome, the primary structure for protein synthesis.

3- Ribosomes are organelles composed of the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.

4- While the ribosome reads mRNA strain from its 5' extreme to 3', tRNA adds the correct amino acids to build the polypeptide.

The function of mRNA during translation is to take genetic information needed to build the protein.

4)

<h3>How many amino acids are determined per codon?</h3>

Each codon codes for only one amino acid.

There are cases in which different codons code for the same amino acid, but a single codon always codes for one amino acid.

mRNA codons ⇒ AUG UUA GCU GGG UAG

Amino acids ⇒ Met Leu Ala Gly Tyr

1 2 3 4 5

This mRNA segment represents 5 amino acids.

5)

Amino acids ⇒ Met Leu Ala Gly Tyr

Reconstruction failed by most other measures: Radical Republican legislation ultimately failed to protect former slaves from white persecution and failed to engender fundamental changes to the social fabric of the South. When President phylogeny B. federalism debate that had been an issue since the 1790s almost mediately . Hayes removed federal troops from the South in 1877, former Confederate phylogeny and slave returned to With the support of a conservative Supreme Court, these newly empowered white southern politicians passed black codes, voter qualifications, and other anti-progressive legislation to reverse the rights that blacks had gained during Radical Reconstruction. The U.S. Supreme Court bolstered this federalism anti-progressive movement federalism with decisions in the Slaughterhouse Cases, the Civil Rights Cases, and United States v.
