Answer:
CAT - GGC - TAC mutates to CAT - GGC - TAG
Explanation:
Changes occur in the nucleotide sequence of the DNA molecule. These changes referred to as MUTATION are usually due mistakes during DNA replication or induced by mutagens (mutation-causing substances). Mutation can be of different types depending on the kind of change that occured to the nucleotide sequence. Based on this question, one of the mutation types is SUBSTITUTION MUTATION.
Substitution mutation is a kind of mutation in which one or more nucleotide base replaces another in the sequence.
The option that suits an example of substitution mutation is: CAT - GGC - TAC mutates to CAT - GGC - TAG because Guanine nucleotide replaces Cytosine nucleotide in the third CODON i.e. TAC becomes TAG.
The correct answer is: C) Metabolism consists of all the energy transformation reactions in an organism.
Metabolism can be defined as the sum of all chemical reactions that occur in living organisms. The functions of metabolism include:
• the conversion of food to energy necessary for proper cell function (transformation of the chemical energy stored in food molecules into energy that can be used for cellular processes)
• the conversion of food to building blocks (amino acids, free fatty acids, nucleotides, monosaccharaides) for macromolecules (proteins, lipids, nucleic acids, carbohydrates)
• the elimination of nitrogenous wastes.
Reactions of metabolism can be catabolic (breaking down) or anabolic (synthesis) and also spontaneous (energy release) and non-spontaneous (require energy).
Answer:
They have genetic material.
Explanation:
All three domains and viruses have genetic material. They have to, otherwise they couldn't reproduce, whether sexual or asexual. In viruses, it can be RNA or DNA; obviously in eukarya it tends to be DNA, remembering that humans are eukaryotes; and in the other two domains a similar pattern is followed.
Why not the other options?
They are composed of cells
- Viruses technically don't have "cells," and even to say cells plural can be a misnomer for some of the more simple forms of life that are unicellular.
They are living things.
- All three domains are alive (bacteria, archaea, eukarya) but viruses are technically not considered to be alive.
They have organelles.
- Eukarya and prokarya technically both have organelles (think of prokaryotic ribosomes), but not all groups that you mentioned have organelles. Remember that organelles ("little organs") are specific groups of cells performing a function, and they usually have names.
