ATI TEAS 7 FULL STUDY GUIDE (SMART
EDITION): SCIENCE - GENETICS AND DNA
QUESTIONS WITH ACCURATE ANSWERS
______________________ is the first step in using DNA to direct the
making of a protein. correct answer Transcription.
A _____________ cell contains only one homologue of each
chromosome. correct answer haploid (n)
Adenine and guanine belong to a class of large, organic molecules
called _____________________. correct answer purines.
Adenine pairs with _________________. correct answer Thymine (T).
At what rate does transcription proceed? correct answer About 60
nucleotides per second.
Biologists can predict the probably outcome of a cross by using a
diagram called a __________________. correct answer Punnett square.
Each copy of a factor, or gene, is called a(n) _________________.
correct answer allele.
, Each nucleotide of DNA is constructed of these 3 parts. correct answer
1. a phosphate group.
2. five-carbon sugar.
3. nitrogen base.
Explain how transcription stops. correct answer RNA polymerase (an
enzyme) reaches a stop codon on the DNA and releases the RNA
molecule.
Explain transcription. correct answer This process "rewrites" the
information in a gene in DNA into a molecule of messenger RNA.
Guanine pairs with _________________. correct answer Cytosine (C).
T/F: A single molecule of DNA has thousands of genes. correct answer
True.
T/F: Gregor Mendel's experiments were done with garden peas. correct
answer True.
The 2 copies of each chromosome are called ____________________
chromosomes, or _____________________. correct answer
homologous, homologues.
