Answer:

The correct answer would be "population size is limited by the availability of resources".

Limiting factors in an ecosystem such as the availability of resources or food limit the growth rate of a population in any ecosystem.

The population size can not reach beyond the carrying capacity of the ecosystem.

The carrying capacity can be defined as the maximum size of a population ecosystem support without getting any adverse effects.

Identify all the amino acid-specifying codons where a point mutation (a single base change) could generate a nonsense codon.

Murrr4er [49]

Answer:

Glutamic Acid (Glu): codons GAA, GAG

Glutamine (Gln): codons CAA, CAG.

Lysine (Lys): codons AAA, AAG, UCG

Serine (Ser): codons UCA, UCG

Leucine (Leu): codons UUG, UUA

Tyrosine (Tyr): codons UAC, UAU

Tryoptophan (Trp): codon UGG

Arginine (Arg): codons CGA, AGA

Glycine (Gly): codon GGA

Cysteine (Cys): codon UGU

Explanation:

Non sense codons are: UAA, UAG, UGA. Then following the genetic code (see attached file) a single base substitution in any of the codons indicated in the answer could generate a stop codon. This single base substitution might happen in the first, second or third base of the codon.
