active cell division
what is mitosis?
a type of cell division that requires 2 parents, fertilization, gametes, and creates genetically diverse offspring
what is sexual reproduction?
cells that multiply uncontrollably and do not function
what are cancer cells?
A specific sequence of DNA that contains information to produce all or part of a protein molecule.
what is a gene?
long strands of DNA found in the nucleus of every cell. Every human has 46
what is a chromosome?
a pair of duplicated chromosomes
what are sister chromatids?
cell division that requires one parent and creates genetically identical offspring
what is asexual reproduction?
a cancer treatment that halts mitosis throughout the body
what is chemotherapy?
the macromolecule "machine" composed of two rRNA subunits are nucleotides. true or false?
false
Genotypes are the underlying genetic makeup. true or false?
true
phase in which the cell carries out normal functions and duplicates chromosomes
what is interphase?
haploid cells that form a zygote
what are gametes?
The spread of cancer cells from their site of origin to sites distant in the body
What is metastasis?
the first stage of gene expression that copies the instructions to build a protein.
what is transcription?
if a person is this, they have two different alleles. (Rr)
what is heterozygous?
phase in which the nucleus splits into 2 duplicate cells
what is the mitotic phase?
the cells in the human body that are diploid, not gametes
what are somatic cells
Which form of tumor can metastasize and is considered cancerous: benign or malignant?
Malignant (benign tumors cannot spread)
enzyme responsible for opening DNA double helix and assembling complementary mRNA strand to template DNA strand.
what is RNA polymerase?
When both alleles are expressed
what is codominance?
all cells that reproduce via mitosis are genetically identical. true or false?
true
the cause for genetic diversity in meiosis
what is crossing over?
cancer cells are able to multiply uncontrollably because they lack this cell process
what is contact inhibition?
a technology that effectively "edits" genes. Cas9 and gRNA remove faulty gene and replace with functioning gene.
what is CRISPR?
a cross between two individuals that are heterozygous for a different trait.
what is a monohybrid cross?
