Weegy: It allows sodium and potassium to move against their concentration gradient. -is why active transport is necessary for the sodium-potassium pump to work.
User: What condition is required for fermentation to occur?
Weegy: When oxygen levels within a cell are too low for aerobic respiration is required for fermentation to occur.
User: The enzyme DNA polymerase works only in the 5' to 3' direction. How does this affect the leading strand and the lagging strand?
Weegy: The enzyme DNA polymerase works only in the 5 to 3 direction. [ DNA polymerase can work continuously on the leading strand but works discontinuously on the lagging strand, creating Okazaki fragments is how this affect the leading strand and the lagging strand.

User: How is DNA copied?
Weegy: The sense strand of DNA is used as a template to create both strands of the new double helix. -is how DNA is copied.
User: is part of the ribosome, helping to catalyze protein synthesis.
Weegy: rRNA is part of the ribosome, helping to catalyze protein synthesis.
User: was a key technique used to explain the structure of DNA
Weegy: X-ray crystallography was a key technique used to explain the structure of DNA.
User: Why are well-defined reading frames critical in protein synthesis?
Weegy: Without a well-defined reading frame, the peptide made from a given sequence could be completely different is why well-defined reading frames critical in protein synthesis.
User: Sickle-cell anemia is caused by a mutation in the gene encoding hemoglobin, causing red blood cells to appear
Weegy: Sickle-cell anemia is caused by a mutation in the gene encoding hemoglobin, causing red blood cells to appear half-moon shaped.
User: What is the function of the start codon of an mRNA sequence?
Weegy: The start codon signals for the ribosome to begin assembling amino acids at that point in the mRNA sequence. [ - is the function of the start codon of an mrna sequence.
