Answer:

One amino acid

Explanation:

This question is describing the occurrence of the process of mutation, which is the alteration in the genetic sequence of a gene. In this question, a DNA sequence was given as follows: TAC-ATC-CAT-CAG-TTA-CGC. However, a SUBSTITUTION MUTATION took place in such a way that the thymine base was replaced by a guanine base to have mutated sequence: GAC-ATC-CAT-CAG-TTA-CGC.

Since the mutation is a kind of substitution mutation, only the codon affected by that mutation will change. This DNA sequence will be transcribed into a mRNA sequence. The mRNA will be read codon by codon (a group of hree nucleotides) to produce amino acid. Since one codon will be involved, one amino acid will be affected.

_____________contents empty into the small intestine and must quickly be neutralized to prevent damage to the intestinal wall. U
Sonbull [250]

Answer:

Pancreatic juice, NaHCO₃.

Explanation:

The buffers are the chemical solution which neutralizes the acidic effect and the human body also produces the biological buffers which help maintain the pH.

The pancreatic juice secreted by the pancreas gets drained into the duodenum of the small intestine and neutralizes the effect of the acidic content in the stomach bolus.  The pancreatic juice contains the sodium bicarbonate which neutralises the effect of the HCl.

Thus, Pancreatic juice, NaHCO₃ is the correct answer.

List the 3 types of cell junctions and state which is the most and least permeable.
Zanzabum
1) occluding junctions
2) anchoring junctions
3) communicating junctions
Occluding junctions do not totally seal the space between cells and the resulting permeability varies greatly.  I would say anchoring junctions are most likely with one of the other 2 junctions being least permeable.
