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.
DNA mutations that actually originate in the gametes is mainly responsible for genetic biodiversity existing in modern organisms. The term biodiversity actually refers to the variety as well as variability of life that is found on the planet earth. his variety can be seen between species, the ecosystem and within the species.<span />
Hazardous substances are dangerous substances while toxins are poisonous substances. Hazardous substances may cause harm to an individuals health; they include acute toxins such as cyanide; substances harmful after repeated or prolonged exposure such as mercury and silica, among others. Toxic substances can be poisonous or cause health effects.
DNA replication follows the base pairing rule (A with T and G with C). This ensures identical replication of the genetic information; hence it's conservation. Each daughter DNA double helix contains one old strand of DNA and one newly-synthesized strand of DNA. This is known as the semi-conservative mechanism.
DNA replication also occurs during mitosis which produces haploid gametes. Each parent contributes half of the genetic information during fertilization of two gametes, thus regenerating the diploid number. Genes from both parents are transmitted to the offspring.
