Met-Gly-Asn-His-Arg-Opal

What is the significance of the first and last codons

Explanation
The first codon is the initiates ion codon specifying the methione as the starting aminoacid
The Last codon is for Opaline which is the stop codon specifying the end of the translationWhat meaning do these codons have for protein synthesis Explanation

AUG codon has two functions, one for the coding of the methionine amino acid and the second (Initiation) is the function of initiating the start of the aminoacid sequence formation

In protein synthesis both these codons signify the start and stop codons for start and stop signals in the steps of translation respectively.

Does the protein sequence change for either of these examples  If so, how Response Yes Likely to change because changes in amino acid sequence of the protein would alter the configurations on the final protein formation into a tertiary and quaternary structureExplain in general  why a change in amino acid sequence might affect protein function.

Explanation  Changes in amino acid sequence of the protein would alter the configurations on the final protein formation into a tertiary and quaternary structure. These final structures are important and vital for their specific function as an ezyme. GRAPHIC ORGANIZER

How do both meiosis and sexual reproduction (fertilization) produce offspring that differ genetically from the parents
Include steps in meiosis that increase variability
Include the process of fertilization.
Explanation

During zygotene and diplotene stages of Prophase I of meiosis crossing over between the homologous chromosomes takes place This results I new combinations of genes on the homologous chromosomes. These new combinations increase the chances of variability  in the progeny.

During fertilization half of the total parental chromosome complement come together in the zygote   These chromosomes come together in a homologous manner  contributing to double chromosome sets in the zygote and its subsequent stages of the somatic cells.
