anticodon on tRNA
Which of the following statements is true with respect to initiation of transcription in
prokaryotes and eukaryotes? - answer>>prokaryotes attract RNA polymerase largely by DNA
sequences in the promoter while eukaryotes build a complex structure of proteins that attracts
NRA polymerase to the promoter
By which mechanism does termination of translation begin? - answer>>a release factor protein
binds to A site of the ribosome
Various forms of the same gene are called? - answer>>alleles
,An organism with two copies of exactly the same allele is called what? - answer>>homozygous

ribosomal sub unit
What structure would you expect to find a the P site during elongation in translation? -
answer>>tRNA bound to growing protein
Which of the following is NOT true about the X chromosome in humans? - answer>>It only
contains genes that are involved in sex determination
In mitosis, during which has do centromeres split and chromosomes begin to pull apart? -
answer>>anaphase
What is a nondisjunction? - answer>>the incorrect separation of chromosomes during meiosis
What is the genetic basis of a trait such a skin color in humans in which you see as a continuum
of slightly different phenotypes present in a normal distribution? - answer>>the trait is
encoded by multiple genes
Which of the follow statements is true with respect to the location of transcription and
translation in eukaryotes? - answer>>transcription occurs in the nucleus and translation occurs
outside the nucleus
