6-48 In somatic cells, if a base is mismatched in one new daughter strand during DNA replication, and is not repaired, what frac

Answer:

1/4

Explanation:

DNA replication is semi-conservative, which means that during this process one DNA strand will be from the original DNA template, whereas the other DNA strand will be newly synthesized. In the first round of DNA replication, daughter cells receive a DNA molecule containing one original DNA strand and one newly-synthesized DNA strand (in this case, one of these daughter cells will contain a mismatch). If the mismatch is not repaired, then in the second round of replication the DNA molecule containing the mismatch would separate during replication, and the DNA strand containing the erroneous nucleotide will serve as a template for the synthesis of a new DNA molecule, thereby producing a permanent mutation.

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.

When selecting among multiple possible phylogenetic trees that fit our data, we commonly use the principle of _____, which means
nordsb [41]

a. parsimony; simplest; fewest

When selecting among multiple possible phylogenetic trees that fit our data, we commonly use the principle of <u>parsimony</u>, which means we choose the <u>simplest</u> possible hypothesis. In phylogenetic analysis, that means selecting the tree that represents the <u>fewest</u> evolutionary changes or mutations.

Explanation:

Phylogeny describes the evolutionary history of on organism or group of organisms.  

A phylogenetic tree structure is used to describe the relationship between various organisms which have originated from common ancestors.  

The Principle of Parsimony is best applied while constructing phylogenetic tree.  

This principle emphasizes on simple observations on a phylogeny which requires only few changes or variations which explain for the difference between the phylogenic sequences.  

This tree structure will only have few specific genetic variations or mutations or evolutionary changes which took place through new appearance of a trait or disappearance of an existing trait.

Which of the following statements is not true of antibody staining? Which of the following statements is not true of antibod
Free_Kalibri [48]

Answer:

The statement that is not true for antibody staining is it can provide information about gene expression.

Explanation:

Antibody staining is important aspect of applied immunology. Antibody staining is done to determine a specific protein in a given sample.Antibody staining is done by using fluorescent dyes and also by using specific enzyme such as horse reddish peroxidase,alkaline phosphatase.

         Antibody staining can be visualized with either fluorescent or radioactive labels. Antibody staining can be performed by western blotting method.Multiple antibodies can be used to stain different proteins.Antibody staining requires the hybridization of the complementary base sequence of the antibody and also the target protein to which it binds.
