Proofreading

7.6K
Synthesis of new DNA molecules is carried out by the enzyme DNA polymerase, which adds nucleotides on the daughter strand complementary to the template DNA strand. DNA polymerase has a higher affinity to add the correct base and ensures fidelity during DNA replication. Furthermore,  it exhibits proofreading activity during replication, using an exonuclease domain that cuts off incorrect nucleotides from the nascent DNA strand.

Nonsense-mediated mRNA Decay

9.4K
The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual role, but they need to work in collaboration. Upf1 is an ATP-dependent RNA helicase that unwinds the RNA helix. Because Upf1 can unwind any RNA, Upf2 and Upf3 are required to help Upf1 discriminate between nonsense and normal mRNAs.
Usually, Upf3 binds to an Exon Junction Complex (EJC) at mRNA splice sites. If a ribosome fully translates the mRNA,...

Forgetting

543
Forgetting is an intrinsic aspect of human memory, characterized by the gradual loss or inaccessibility of information over time. Hermann Ebbinghaus, a pioneering psychologist, extensively studied this phenomenon and formulated the forgetting curve. This curve illustrates that memory loss occurs rapidly immediately after learning and then decelerates over time. Several mechanisms contribute to forgetting, including encoding failure, storage decay, retrieval failure, and interference.
Encoding...

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Clinical Neurology

Background:

  • Unilateral Spatial Neglect (USN) significantly impacts daily life.
  • Prose reading is a sensitive USN indicator, but its relation to other neglect measures is unclear.

Purpose of the Study:

  • Investigate the relationship between prose reading neglect (PRN) and other neglect measures.
  • Explore PRN's link to neglect severity and single-word reading.
  • Identify neural correlates of PRN.

Main Methods:

  • Assessed 30 right-hemisphere stroke patients with USN using prose reading (one/two columns), single-word reading, and 13 neglect tests.
  • Analyzed lesion sites in participants with and without PRN.

Main Results:

  • 70% of patients exhibited PRN, omitting words at the text's start.
  • PRN was associated with greater overall neglect severity and specific lesion locations (insula, putamen, superior temporal gyrus).
  • Double dissociations between PRN and single-word reading neglect suggest distinct cognitive processes.

Conclusions:

  • Prose reading is a complex task uniquely affected by USN.
  • PRN assessment is crucial for predicting neglect effects and informing clinical practice.
  • Findings suggest parallel processing for single words versus serial analysis for text.
