1) a mutation occurs in which an AAA codon, which signifies lysine, into AGA which signifies a chemically similar amino acid arginine. This is an example of a ____ mutation?

a) conservative nonsynomous b) frameshift c) nonsense d) conditional e) silent

It has to be neutral mutation, but the option for neutral is not given... would it be conditional?

2) Which of the following types of inheritance could account for an affected male having all affected daugters but no affected sons?

a) autosomal recessive b) autosomal dominant c) Y-linked d) X-linked recessive e) X-linked dominant

it has to be dominant... so its either b or e?

3) The site where RNA polymerase binds to the DNA template is called the ____ sequence.

	a)	enhancer
	b)	promoter
	c)	domain
	d)	terminator
	e)	reading frame

Solutions

Expert Solution

1.ANSWER: a)

A nonsynonymous substitution results in a change in amino acid that may be arbitrarily further classified as conservative.

2. e)

All daughters of an affected father will also be affected but none of his sons will be affected.

3. promoter

the binding of RNA polymerase and the initiation of transcription. Only after certain transcription factors are attached to the promoter does the RNA polymerase bind to it. The completed assembly of transcription factors and RNA polymerase bind to the promoter, forming a transcription initiation complex.

A mutation occurs in a bacterium. Because of this mutation, DNA synthesis occurs at a very low rate. Upon analysis, it is found to have normal levels of activity of DNA polymerase I and III, DNA gyrase, and ligase. It also makes normal amounts of the wildtype dnaA, dnaB, dnaC, and SSB proteins. The sequence of the OriC (the origin of replication) of its chromosome is found to be normal (wildtype). What defect might account for the abnormally low rate...

How would the mutation described above, changing a lysine to an arginine alter the histone code if this lysine was located on the histone tail? What possible effects could this have? Histone proteins are the most conserved proteins of all eukaryotic proteins. That is to say that there is very little variation in the sequence of amino acids from one species to another. Why do you think this is? Please note that this is a 10 point question, please provide...

A certain genetic mutation occurs in 5% of the population of Whoville. The mutation causes otherwise normal adult Whos to grow green tail feathers during full moons. A test for this mutation has a sensitivity of 95% and a specificity of 98%. This means that the probability that a Who with the mutation tests positive is 95%, and the probability that a Who without the mutation tests positive is 100%-98%=2%. If a random adult Who is tested for the mutation, then...
