Concept explainers

Genome annotation

The technique of linking biological information to genome sequences is termed genome annotation. Gene annotation is the method of identifying gene locations and coding sections. It helps us understand what these genes are doing in the body through establishing structural characteristics and linking them to the actions of various proteins.

What does it mean when we say that the genetic code contains degeneracy? Discuss the universality of the genetic code.
In how many cases in the genetic code would it NOT be possible to know the amino acid specified by a codon if only the first two nucleotides of the codon are known?
Explain what each genetic code means #1- #2- #3- #4
The genetic code is thought to have evolved to maximize genetic stability by minimizing the effect on protein function of most substitution mutations (single-base changes). We will use the six arginine codons to test this idea. Consider all of the substitutions that could affect all of the six arginine codons.(a) How many total mutations are possible?(b) How many of these mutations are “silent,” in the sense that the mutantcodon is changed to another Arg codon?(c) How many of these mutations are conservative, in the sense that an Argcodon is changed to a functionally similar Lys codon?
If there are 64 possible codons in the genetic code and the amino acid is specified by each, as read in the 5’ to 3’ direction from the mRNA sequence, which ones are STOP codons?

The genetic information contained in DNA consists of a linear sequence of coding units known as codons. Each codon consists of three adjacent DNA nucleotides that corresponto a single amino acid in a protien. The E.coli DNA molecule contains 4.70 x 10^6 base pairs. Determine the number of codons that can be present. Assuming that the average protein in E.coli consists of a chain of 400 amino acids, calculate the maximum number of protiens that can be coded by an E.coli DNA molecule.
