A) In how many cases in the genetic code would you fail to know the amino acid specified by a codon if you knew only the first t
Vesna [10]

Answer:

a) 28 cases

b)  3 cases

Explanation:

a) From the table of genetic codes, there are 28 codons that specify more than one amino acid assuming only the first two nucleotides are considered. In these cases, one cannot outrightly specify the amino acid the genetic codes are coding for without knowing the last nucleotide of the codes. <em>For example, UU can be for Phenylalanine or Leucine, CA can be for Histidine or Glutamine, etc. </em>

b) From the table of genetic codes, the first two nucleotides of Arginine can be either of CG or AG, that of Serine can be either of UC or AG while that Leucine can be either of CU or UU. Only in these <u>3 cases</u> would one fail to know which are the first two nucleotides assuming the name of the amino acids are given.

<em>See the attached image for the genetic code.</em>

How can a diet that is 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohy
jeyben [28]

Answer:

Due to increase or decrease in the concentration of carbohydrates have no effect on protein concentration.

Explanation:

A diet having 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates because with the increase or decrease of carbohydrates in the diet does not increase the amount of protein. Protein and carbohydrates are two different things, proteins broken down into amino acid that is utilize by the body for making muscles while carbohydrates are broken down into glucose that is used by the body for performing daily activities.

Suppose that the string of A nucleotides following the inverted repeat in a rho-independent terminator was deleted but that the
eimsori [14]

Answer: is seen below

Explanation:

Termination will not take place if the strings of A nucleotides following an inverted repeat of rho- independent termination ( which forms an hairpin structure)were deleted. Although, RNA polymerase may pause briefly at the hairpin, the presence of A- U base pairs is needed to destabilize the DNA - RNA interaction and to end transcription. If the string A nucleotides is not present, then transcription of RNA polymerase will continue.
