In general, being more emotionally stable and mature is a characteristic of which stage of adulthood? a. childhood b. young adulthood c. middle adulthood d. older adulthood

Maturity occurs in young adulthood also known as adolescence. At this stage, many chances occur physically, mentally, phsychologically, and emotionally. That means the answer to your question is B. 

I hope this helps:)

I believe C- Middle adulthood. Because around this time you most likely have a job and kids. If you're going to have these things you are most likely emotionally stable and overall mature.

The correct answer is - 3 (two codons of 507th that are U, C, and the first nucleotide of 508th codon U).

Explanation:

Each amino acid is coded by a three-nucleotide base long codon. So in the case of the F508del variant, there is a deletion of three nucleotides that is encoded for phenylalanine amino acid.

In this isoleucine is encoded by 507th codon that is AUG and 508th codon is UUU codes for Isoleucine.

In this case, two codons of 507th are U, C, and the first nucleotide of 508th codon U. So overall three nucleotides are deleted in the F508del variant..
