Beginning within the nucleus, the first step leading to the synthesis of a polypeptide is _____.

Biology
1 answer:
Natalka [10]3 years ago
3 0

Answer:

The correct answer to the question is : Transcription.

Explanation:

  • The synthesis of a Polypeptide chain or Protein begins by the coding of the amino sequence, first, from the DNA sequence code into an intermediate mRNA sequence code. The mRNA sequence code is then converted into the amino acid sequence code.
  • The genetic material is comprised of genes, each of which encodes for a particular protein.
  • The DNA (deoxyribonucleic acid) sequence code of the gene is converted into an intermediate mRNA (messenger Ribonucleic Acid) by an enzyme called the DNA dependent RNA polymerase by utilising ribonucleotides and ATP (adenosine triphosphate as energy). This process is known as Transcription.
  • Transcription happens inside the cell's nucleus.
  • The resulting intermediate mRNA message is transported from the nucleus into the cytoplasm.
  • In the cytoplasm {or on Endoplasmic Reticulum (ER)}, the mRNA message is recognised by the Ribosomes (protein synthesising machinery) and are converted into polypeptide sequence by using amino-acyl tRNA synthase and ATP ( as energy). This process is known as Translation.
  • The polypeptide chain folds in the proper orientation to give rise to the functional proteins.

<h3>What is the role of the oral dentist?</h3>

Tooth extractions are carried out by dental and oral specialists for various reasons. A painful tooth or a tooth that has been significantly affected by decay may be the problem. Sometimes a dentist will extract a tooth to make room for dental prostheses or other devices.

When the situation becomes increasingly complicated, an oral expert rather than a dental professional may need to extract a tooth. They typically remove wisdom teeth or third molars.

The dental professional or specialist will initially numb the tooth to gradually relax the patient. Even though tooth extraction may still be distressing, it may be essential for relieving dental pain and preventing further problems.

List these events in the correct order for CSF flow in the CNS. a: CSF flows into the arachnoid villi b: CSF enters the blood c:
alex41 [277]

Answer:

E-----> C------>D------->A------->B

Explanation:

The cerebrospinal fluid (CSF) is the fluid of the central nervous system. It allows for buoyancy as the brain is immersed in the fluid, protection, excretion of waste products from the brain and many more. The production of CSF is by the CHORIOD PLEXUS  in the lateral, third and fourth ventricles. The CSF flows through the interventricular foramen from the lateral to the third ventricle and from the third ventricle into the fourth ventricle through the cerebral aqueduct which connects them. The CSF then flows into the subarachnoid space. Absorption of CSF into the blood is by the arachnoid villi and then the CSF enters the blood.

If the specific gravity of urine is 1. 020 in the sample of urine, what caused the filtrate to increase its s. g. between bowman
frutty [35]

Because more water than solutes are reabsorbed between Bowman's capsule and the collecting duct, specific gravity rises.

<h3>What is bowman's capsule?</h3>
  • The Bowman's capsule, a component of the nephron, creates a sack that resembles a cup and surrounds the glomerulus.
  • The "Bowman's space," which is adjacent to the proximal convoluted tubule of the nephron and signifies the beginning of the urinary space, is enclosed by Bowman's capsule.
  • The glomerulus is protected by a two-walled pouch called Bowman's capsule.
  • Bowman's space is the term for the area between the capsule's walls.
  • The glomerular capsule, the Malpighian capsule, and the renal corpuscular capsule are among additional names for Bowman's capsule.
  • The Bowman's capsule is a portion of the human kidney's nephron.
  • By permitting water molecules and tiny molecules of other substances to flow through its selectively permeable membrane, Bowman's capsule performs the ultra-filtration process.
  • Thus, glomerular filtrate is formed.
