Which of the following best describes the central dogma of molecular biology? A) mRNA is transcribed into DNA, which is then translated into a protein B) DNA is transcribed into mRNA, which is then translated into a protien C) DNA is translated into mRNA, which is then transcribed into a protein D) DNA is replicated into mRNA, Which is then transcribed into a protein E) mRNA is translated into DNA, which is then translated into a protein

Eukaryotic cells contain O a) 5 nuclear RNA polymerases b) 3 nuclear RNA polymerases O c) 6 nuclear RNA polymerases O d) none of these is true that transcribe distinct classes of genes.

The protein neuroD is a critical human protein translated in the brain during development. The protein is 357 amino acids long. What is the length of the human neuroD *gene* sequence? a)357 nucleotides b)1071 nucleotides c)119 nucleotides d)You cannot determine the length of the gene from this information alone.

Parents who both have "sickle-cell trait", i.e, are heterozygous for HbS have a child who is tested at birth, and is found to be homozygous for HbS (both alleles affected). What is the molecular reason why the child presents with no symptoms until 6 months of age? a.) the mutation affects the beta chain, which is not dominant at birth b.) the mutation affects the alpha chain, which is not dominant at birth c.) babies cannot be exposed to low oxygen that triggers symptoms d.) babies cannot be exposed to high oxygen that triggers symptoms

Histone H1: a) makes up the core particle  b) associates with linker DNA c) is not present in the 30 nm fiber  d) none of the above

There are two broad classes of transposons. Each class is characterized by its method of "jumping" (either through an RNA intermediate or via excision and insertion) True False   Most mutations of evolutionary significance are A)induced B)spontaneous..
