Suppose that part of an amino acid sequence of a protein changed from tyrosine-proline-glycine-alanine to tyrosine-histidine-glycine-alanine. This change was most likely caused by a point mutation called a <u>substitution</u>.

<u>Explanation:</u>

Any protein is synthesized by joining a number of amino acids together. This amino acid is placed based on the sequences of the DNA , for every 3 sequence there is an amino acid that is synthesized and therefore it is called as a triplet codon, since there may be many sequence for a single amino acid we call it as degenerate codon.

Which word equation summarizes the hydrolysis of a carbohydrate?
maria [59]

Answer: Option C) sucrose + water-glucose + fructose

Explanation:

Sucrose, is a dissacharide (carbohydrate with two simple sugars) composed of glucose and fructose units. Thus, on hydrolysis (addition of water to split a compound) sucrose yields its constituent units.

Thus, the correct answer is that adding water to sucrose splits it into glucose and fructose

Would you expect that anions would be physically closer to the oxygen or to the hydrogens of water molecules that surround it in
marshall27 [118]
Anions are negatively charged particles. The water molecule is a polar molecule, that means that, it is partly positive and partly negative. The oxygen atoms in the water molecules are more electronegative more than the hydrogen atoms and they draw the shared electron nearer to themselves than the hydrogen atoms; this make them to be slightly negatively charged while the hydrogen atom is slightly positively charged.
Therefore in solution, the anions would be attracted toward the hydrogen atom that is slightly positive while the cations will be attracted to oxygen atom that is slightly negative.

How many atoms are in a 70 kg human?
topjm [15]

Answer:

7 followed by 27 zeros

Explanation:

The body of an adult man weighing 70 kg is made up of approximately 6.7 • 10 ^ 27 atoms.

The body of an adult male contains approximately 57% water, but if we look by weight, hydrogen is only 11%, while if we look at the mutual ratio of atoms in water, there are a total of 67% hydrogen atoms.

In this way, most of the weight (mass) of the human body comes from oxygen, but most of the atoms in the body are hydrogen.
