Answer:

Explanation:

When a substance has the  capacity to disrupts the genetic compositions (DNA) of the  organisms, to the extent that it makes the  particular organism genetic materials prone to genetic mutation,( random changes in the genetic composition) such group of substances are called Mutagens.

ionizing radiation,radioactive decay are  some examples of  of physical mutagens, while biological mutagens examples include viruses and bacterial. Chemical mutagens are Benzene compounds,bromine,aromatic amines,sodium Azide.

They exerts their negative effects

by disrupting gene expression sequence of transcription, translation, or changed the nucleotides  sequence of the DNA leading to  deletion, addition, subtraction of genetic bases.Some may make chromosomes to be unstable, disrupting the structure

 Although some mutagens can cause cancer, that is they are mutagens. not all mutagens  carcinogenic.This is because the Mutagenic effects depends on the metabolites present in the cells of the organisms.

maxonik [38]
The sequence AAU GGC UAC is composed of three codons each of which codes for a different amino acid. AAU codes for the amino acid called threonine. GGC codes for the amino acid called glycine UAC codes for the amino acid called tyrosine. So the chain will read  threonine-glycine-tyrosine. There are 64 possible 3 - letter combinations of DNA coding units A, C, G and T. Of these, there are three stop or non- sense codons that do not code for any amino acid, while the remaining 61 code for different amino acids.

Paraphrasing is the act of rewording, revising, simplifying and expressing the text in your own words with additional clarity. Note that condensing the text to a shorter form should not be in your interests because that would be summarizing, not paraphrasing. Check this out:

Nonliving organisms and lifeless organisms are not the same thing. Inanimate organisms are not dead, they're nonliving. Being nonliving means not having a characteristic of life, it means that the object is inorganic. A valid example could be a rock. A rock has never had a characteristic of life. Being deceased means that life once inhabited the being and has left it. Just as a moose gains life from conception, it's deemed dead once life has left it. In science, nonliving organisms and lifeless organisms are not the same thing; one was gifted life and one was inanimate from the beginning.

Answer:

The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.
