4 The RNA copy of DNA that leaves the nucleus %26amp; travels to the cytoplasm to make proteins is what?


5 The nucleotide sequences on DNA that actually have information encoding a sequence of amino acids are what?


6 The enzyme used to make a DNA copy complementary to processed mRNA is what?


7 How many genes constitute the human genome?

Thanks so much!

1) endoplasmic reticulum ( or, perhaps Golgi body )





2.) mitochondria and chloroplasts





3.) incomplete dominance





4.) mRNA ( messenger )





5.) exons ( or codons )





6.) polymerase





7.) 22 to 33 thousand ( this is not settled )





8.) transpnsons ( jumping genes )
Reply:You should do your own homework and search into your textbooks!!


1 Golgi Apparatus (or Golgi Body)


2 Chloroplasts and mitochondria (due to some symbiosis history)


3 Codominance/ Incomplete dominance/ Blending inheritance


4 mRNA (messenger RNA)


5 codons (please please read your textbooks; three nucleotide sequences is called one codon, which codes for one amino acid)


6 RNA-dependent DNA polymerase (because it works on mRNA so we have the term "RNA-dependent", and because it produces DNA so we have the term "DNA polymerase")


7 approximately 25,000 (source from http://en.wikipedia.org/wiki/Human_Genom...


8 Tranposons (the jumping genes)
Reply:You need to start searching by your own! It's important, otherwise your not going to learn anything, or less read it and the biology is too interesting for not to read it
