Atoms become positively charge when they lose electrons and become positively charged when they gain electrons
gulaghasi [49]3 years ago

Explanation:

Atom becomes negatively charged when it <em>gains</em><em>*</em> electrons.

It becomes positively charged when it loses electrons.

I think electrons play a major role in the determining charges of ions (atoms that loses or gain electrons).

hopefully this makes sense.

SpyIntel [72]

The sequence has not been given. It has been attached.

Answer:

QPGREDRPLP

Explanation:

A codon consists of a set of three mRNA nucleotides which corresponds to an amino acid. There are 64 codons which code for 20 amino acids (AA). A DNA sequence is first transcribed to mRNA which is then translated to form protein. According to the given sequence, the first 10 amino acids for this particular sequence will be:

GTC = CAG mRNA = Glutamine AA (Q)

GGT = CCA mRNA = Proline AA (P)

CCA = GGU mRNA = Glycine AA (G)

GCA = CGU mRNA = Arginine AA (R)

CTT = GAA mRNA = Glutamic acid AA (E)

CTG = GAC mRNA = Aspartic acid AA (D)

TCT = AGA mRNA = Arginine AA (R)

GGC = CCG mRNA = Proline AA (P)

GAT = CUA mRNA = Leucine AA (L)

GGC = CCG mRNA = Proline AA (P)

Hence, in single letter codes these amino acids will be represented as :
