what happens in G1 - ANS growth of the cell what happens in G0 - ANS cell exits to this stage when it will not divide what happens in G2 - ANS checks DNA replication, finishes growing, protein replication and most amount of DNA what happens in S - ANS DNA replication what happens in M - ANS Division what is CDK - ANS cyclin dependent kinase used to regulate cell cycle what is cyclin - ANS protein. binds to CDK, helps regulate What happens at the G1/S checkpoint - ANS DNA damage, commits to cell cycle, will divide whats happens at the G2/M checkpoint - ANS check if fully replicated what happens at the spindle assembly checkpoint - ANS checks if the spindle is attached and everything is lined up what does condensin do - ANS protein that condenses DNA what does cohesin do - ANS protein that holds sister chromatids together whats is bi-orientation - ANS it means that everything is aligned symmetrically, and means it can go into anaphase what is a proto oncogene - ANS helps cell growth and leads to cell expression what is an oncogene - ANS a mutated proto oncogene that leads to cancer what is a tumor suppressor - ANS inhibits the cell division/growth, if u get rid of it cancer will occur. what is transcription - ANS DNA to RNA what is translation - ANS RNA to Protein what are the steps in RNA processing (there are three) - ANS 1) 5' Cap 2) Poly A tail/ 3' end 3)splicing is the exon or intron expressed - ANS the EXon is expressed, the intron is is taken away where does the next amino acid bind on the last amino acid - ANS always on the carboxyl group which way does polymerase travel - ANS 3' to 5' which is mRNA polymerized - ANS 5' to 3' which was does translation occur (which way mRNA is read) - ANS 5' to 3' the coding strand to mRNA is..... - ANS the same thing and match T-U (EX. coding 5' TAG 3' and RNA 5' UAG 3') the Template strand to mRNA is..... - ANS opposite direction and complimentary (template 3' GCA 5' and RNA 5' UGC 3') the coding to template strand is..... - ANS opposite direction and complimentary ( template 5' CCG 3' and coding 3' CGG 5') in a cell in M phase, which structures will be genetically identical? - ANS the sister chromatids
