Mutations<span> are errors in codons caused by changes in nucleotide bases</span>
Answer:
3, 1, 4, 5, 2
Explanation:
DNA helicase enzyme will unwind DNA into 2 segments for a template. Complementary nitrogenous bases will attach themselves to one of the DNA strands. mRNA carries codons for instructions from DNA. mRNA leaves the nucleus and joins with a ribosome (tRNA) in the cytoplasm. tRNA has anticodons which are complementary to a specific mRNA molecule. tRNA pairs with and translates instructions that the mRNA is carrying. Each amino acid delivered to the ribosome by tRNA begins forming a chain of amino acids, called a peptide bond.
Four (4) spermatids result from one spermatogonium. Details about spermatogenesis can be found below.
<h3>What is spermatogenesis?</h3>
Spermatogenesis is the process by which sperm cells are produced from the testes of a male animal.
Spermatogenesis involves series of mitotic and meiotic divisions that finally result into the haploid sperm cells.
Spermatids are haploid cells produced by meiosis of a spermatocyte that develops into a spermatozoon.
The spermatogonium divides mitotically into primary spermatocyte which then develops into secondary spermatocyte via meiosis. Each secondary spermatocyte forms 4 spermatids.

Genetic drift is best described as evolution as result of RANDOM CHANCE WITHIN THE POPULATION. Genetic drift refers to the change in the frequency of allele in a particular specie population as a result of random sampling and the random events which determine the survival and the reproduction of the members of the population.
