BI 101 Exam #2 GRCC Questions With
Complete Solutions
adult stem cells: Correct Answers cells in adult
tissues that can give rise to only a few related
types of specialized cells
alleles Correct Answers alternative versions of
genes
for each gene, an organism inherits two alleles,
one from each parent. If the two inherited alleles
are different, the dominant allele determines the
physical appearance; the recessive allele has no
noticeable effect on an organism's appearance
anaphase Correct Answers Phase of mitosis in
which the chromosomes separate and move to
opposite ends of the cell
cancer Correct Answers uncontrolled cell division
invade surrounding tissue and spread elsewhere
cancer cells: Correct Answers Don't display
contact inhibition
Don't need anchorage
Are immortal
chromatin Correct Answers unwound DNA found
throughout interphase
, chromosome Correct Answers (condensed DNA) A
threadlike, gene-carrying structure found in the
nucleus. Each chromosome consists of one very
long DNA molecule and associated proteins.
humans have 46 in their cells
Codominance Correct Answers A condition in
which neither of two alleles of a gene is dominant
or recessive.
codons Correct Answers A three-nucleotide
sequence of DNA or mRNA that specifies a
particular amino acid or termination signal; the
basic unit of the genetic code.
Cytokinesis Correct Answers division of the
cytoplasm. Occurs at same time as telophase.
Cleavage furrow forms in animal cells, cell plate
forms in plant cells
difference between chromosomes and genes
Correct Answers chromosome - condensed DNA
gene - part of chromosome that codes proteins
embryonic stem cells: Correct Answers cells
derived from an early stage of an embryo that
have potential to become any cell type in the body
- would be a perfect match to the patient and not
be rejected if used in the patient
