Basic Genetics Flashcards
Statement that best describes the process of Mitosis?
A. Cell division that produced (two daughter cells) with the same number of chromosomes as the parents cell
B. Cell division of Germ cell
C. Cell division the produces four daughter cells
D. Cell division that produces two daughter cells
A
When a recessive trait is expressed
B. Two genes carrying the trait were present
In a pedigree analysis, which statement of about the symbols used is true?
Deceased family members have a line crossed through the symbol
Which of the following nitrogenous bases make up DNA?
Adenine, Cytosine, Guanine, Thymine
Mutations can occur following DNA replication that escapes the proofreading and repair systems which statement about DNS mutations is true?
All frameshift mutation at the beginning of the coding sequence is most likely to result in a phenotypic change
Which phenotype would be expected fron the mating of a Jk (a+b-) female and a Jk (a-b+) male
Jk (a+b+)
Which statemen describes an intron?
The none coding region of a gene
Statement of isolation of nucleic acid
Silica particles bind DNA under high salt concentrations
The purpose of transcription is to:
Synthesize RNA using DNA as a template
When a male possesses a phenotypic trait that he passes to all his daughters and non of his so s, the trait is said to be:
X linked dominant
When a female possesses a phenotypic trait that he passes to all her sons and non of her daughters, so the trait is said to be:
X linked recessive
Which statement correctly describes DNA replication in eukaryotes?
Bidirectional replication: Requires RNA primer
How is tRNA different from other types of RNA?
It recognizes aminos acids and nucleic acids
Which statement about translation of protein is false?
mRNA delivers the amino acids to the growing peptide chain during elongation
The purpose of meiosis is to:
d. Generate daughter cells that contain half the number of chromosomes of somatic cells that contain new DNA sequences
