How many distinct trnas are needed to translate every codon in the genetic code?
White raven [17]
In the genetic code, codons made of of three bases specify an amino acid. With three bases, there are 64 possible permutations. With three codons corresponding to STOP codons, this leaves 61 combinations that code for an amino acid. This would require 61 distinct tRNA species were it not for the "wobble base"

The number of possible genetically different gametes for an organism equals
masya89 [10]

The organism can produce 12 genetically different gametes.

<h3><u>Explanation:</u></h3>

The gametes are the unit of sexual reproduction which are produced by an organism from their germ mother cell by means of meiosis. This gametes do carry half the amount of total chromosomes that is present inside each cell of that organism. This process let's the genetic combinations of chromosomes to get more variations among offsprings. But this isn't the only source of variation among the offsprings.

Each and every germ mother cell that's undergoing the meiotic division undergoes a process called crossing over and chaismata formation which gives the genetic mixing among the different alleles of same character among the organism.

Thus, statistically, if the organism has n pairs of chromosomes, then the organism will be able to produce 2n number of genetically different gametes which helps in finding out the probability of genotype of the offsprings.

So if the organism has 6 pairs of chromosomes, then the organism will be able to produce 12 genetically different gametes.
