The genetic code contains 61 codons to specify the 20 common amino acids. many organisms carry fewer than 61 different trna genes in their genomes. these genomes take advantage of isoaccepting trnas and the rules governing third-base wobble to encode fewer than 61 trna genes.

yes you are right

Explanation:

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects
