COMPLETE CHAPTERS 1 TO 49 QUESTIONS
ANSWERS GRADED A+
⩥ Gene. Answer: DNA structure that codes for the production of a
protein.
⩥ Gene expression. Answer: Synthesis of a gene product in the form of
an RNA or protein from a gene.
⩥ Genetic code. Answer: Collection of three base sequences called
codons used to translate the nucleic acid information into amino acids
during protein synthesis.
⩥ Genome. Answer: The complete genetic content of an organism.
⩥ Genotype. Answer: The unique genetic information of an organism or
cell.
, ⩥ Heteroplasmic. Answer: A mixture of more than one type of
mitochondrial sequence in one cell.
⩥ Histones. Answer: Basic proteins that bind to DNA to form
nucleosomes, basic units of chromatin.
⩥ Term. Answer: Definition
⩥ Indels. Answer: "Originally, designating a unique class of sequence
variants including both insertions and deletions, resulting in an overall
change in the number of base pairs. Today the term more commonly
refers to either insertions or deletions or a combination thereof."
⩥ Insertion. Answer: "An extra DNA sequence that is present in one
sample compared with a reference sequence."
⩥ Intergenic. Answer: "DNA sequence between genes."
⩥ Intron. Answer: "DNA between exons that do not code for protein and
are removed by RNA splicing."
⩥ Micro RNA (miRNA). Answer: "Small RNAs that are not translated
and function to regulate translation."
