5 True/False questions
anaphase → Second Stage of Cell division: Centromeres of duplicated chromosomes are aligned at plate. chromosomes become attached to spindle fibers
Cell Theory → 1. All living things are made of cells
codon → A sequence of three nucleotide bases on mRNA that refers to a specific amino acid. (if DNA triplets are AAT-CGT-TCG then related _____ on mRNA would be UUA-GCA-AGC
mitosis → Cell's division (PMAT) of the nucleus. Final product is 2 daughter cells that are exactly like the parent cell., asexual reproduction and contains same number of chromosomes.
tight junction → Communicating Junctions; channels that allow small molecules to flow through protein-lined pores between cells. common in the heart and embryonic cells.
