Q

Adenosine monophosphate (AMP)

A

Adenosine monophosphate (AMP), also known as 5’-adenylic acid, is a nucleotide. AMP consists of a phosphate group, the sugar ribose, and the nucleobase adenine. It is an ester of phosphoric acid and the nucleoside adenosine.

Q

phosphodiester bonds

A

anabolic process!

The anabolic processes are the reactions in which the smaller molecules come together to form larger complexes. The process is an endergonic process in which the energy is required for the formation of new bonds to form the larger complex molecules. The water molecule is removed and the phosphate group from 5 carbon of one nucleotide forms a bond with 3 carbon of another nucleotide. This reaction is an example of an anabolic process.

Test 11 Q. 123.

In thin layer chromatography, using silica gel plates, the analytes can ineract with hte silica gel through H bonding. Which of the following classes of compounds would most likely have the strongest interactions with silica gel?

A

B. Carboxlyic acids

Then Alcohols, then esters, then ketones
Carboxlyic acids are ALWAYS more polar than alcohols, bc they can do more H bonding ! Carboxlic acid can do H bonding through carbonyl and OH much more interacting with silica with carboxylic acid compared to alochol!
esters, then ketones

The lung cells of heavy smokers would be expected to have greatly increased concentrations of cP-450 (a protein) and:

A

b. mRNA sequences that code for cP-450

more gene expression, more protein produced from more mrna= more mRNA**** that means more put through factpr, how get many proteins produced from more mrna

not more rRna or tRNA

Q

Tetrahydrofuran (THF, oxolane)

A
72
Q

Compound 3 is prepared from Compound 2 (Figure 2) by:

A.reduction of the ketone and lactonization of the gamma-hydroxyester.
B.hydrolysis of one ester and formation of an acetal from the ketoacid.
C.reduction of one ester and formation of an acetal from the gamma-hydroxyketone.
D.reduction of one ester and the ketone followed by dehydration to a ketoether.

A

gamma-hydroxyester.

First, NaBH4 reduces the ketone to a secondary alcohol, the gamma-hydroxyester intermediate. Secondly, the alcohol group in this intermediate then reacts as a nucleophile with the carbonyl in the ethyl ester in the same molecule, forming a new ester by displacing C2H5OH as a leaving group. This cyclic ester is called a lactone, and the intramolecular transesterification yielding this lactone is called lactonization.

if looking for acetal need one carbon attached to 2 R groups period.

whats a semilogarithmic plot?
paper test 9 Q. 162

A

semilogarithmic plot= one axis that is linear one axis that is logarithmic, logarithmic is powers of 10 so see how y axis of answer choice d is not increasing in a linear way but inc in logarithmic way, interval 1 to 100 to 1000 etc…. going up by powers of 10 there that is logarithmic, x axis is hours going up in linear way!!! that is what semilogarthmic is like half and half

Q 28 Genetics problem set 4.3.24

two parents are carries for an autosomal recessive mutation that is 50% penetrant. What is the probability that their third child is health?

A

6/8 + 1/8= 7/8

76
Q

Q 29 Genetics problem set 4.3.24

A plant species has two traits whose inheritance is controlled in a mendelian fashion. Thick leaves are dominant to thin ones, and creased leaves are dominant to uncreased ones. Assume that these genes reside on separate chromosomes. IF cross is performed between two plants that are thick creased dihybrids, and 320 progeny are obtained, roughly how many will be thin and creased?

A

separate chromosomes is an impotant thing to say because that means they assort independently and you can use 9:3:3:1 ratio! if genes are linked do not have 9:3:3:1 ratio, so cannot solve this problem unless you have other information**
= 60

Q

Acid Bromide
acetyl bromide

A
