Near the end of a marathon race, the first two runners are separated by a distance of 35.0 m. The front runner has a velocity of 3.25 m/s, and the second runner has a velocity of 4.75 m/s. What is the velocity of the front runner relative to the second runner?  

What bond is responsible for the branch points in glycogen and amylopectin?

Here is the sequence around the translation initiation codon (AUG) of a human mRNA: 5’—-AAGGGAUGGAACCUAGC….—-3’ You have isolated a mutant version of the gene encoding this mRNA that contains a frameshift mutation.  A one base pair insertion (base pair is underlined) occurs after the start codon (AUG). This change generates the mRNA shown below: 5’—-AAGGGAUGGAAACCUAGC….—-3’   This mutation will cause a premature stop in:  

What may be the primary mechanism in the evolution of proteins that are composed of domains derived from different ancestral genes?

The _______ is located about 10 bases upstream from the initiation site.  It has the consensus sequence ______ and is responsible for identifying the precise nucleotide at which ________ begins.

Protein Y acts as a repressor for the ABC gene.  If the amount of Y increases in a cell, then the amount of protein produced from ABC will increase.  This statement is: 

You discover alien life with a genetic system based on a DNA-like molecule, but it has 6 bases instead of 4 as happens on Earth. The proteins on the planet are built from combinations of 30 possible amino acids. What would be the minimum number of bases in each codon on this planet?
