Answer 2

The two elements, in looking at their atoms, have a total of 51 protons between them are Magnesium and Aluminum and Lithium and Scandium so option d. both A and B.

What are protons?

The protons are + charges particles found in the nucleus of the atoms.

NO. of protons in :

Magnesium and Aluminum- Magnesium  has total of 12 proton and Aluminum has 13 total protons. Lithium and Scandium-  Lithium has 3 and Scandium has 21

So total no. of protons= 12+13+3+21= 50.

Thus it lies in between total of  51 protons in the periodic table.

The genetic code was elucidated through the use of polyribonucleotide's synthesized either enzymatically or chemically in the laboratory. Given what we now know about the genetic code, how would you make a polyribonucleotide that could serve as an mRNA coding predominantly for may Phe residues and a small number of Leu and Ser residues?
What other amino acid(s) would be encoded by this polyribonucleotide, but in smaller amounts?

Answers

Answer:

The genetic codes are responsible for coding the amino acids. The messenger RNA (ribonucleic acid) consists of triplet codons, which is responsible for the synthesis of respective amino acid sequences. The UUU codes for the phenylalanine amino acids. Similarly, the incorporation of 5 mixtures such as ADP, GDP, CDP, and UDP can alternatively produce the mRNA polymer with the serine and lysine residue in a small amount.

EXPLANATION:

The genetic codes are responsible for coding the amino acids. The messenger RNA (ribonucleic acid) consists of triplet codons, which is responsible for the synthesis of respective amino acid sequences. The formation of the RNA stand is done by using ADP, GDP, CDP, and UDP (adenosine, guanosine, cytosine, and uridine diphosphate). It requires no template for the formation of polymers. Therefore incorporation of UDP is done by the incorporation of polynucleotide phosphorylase, which will result in the formation of poly U. The UUU codes for the phenylalanine amino acids. Similarly, the incorporation of 5 mixtures such as ADP, GDP, CDP, and UDP can alternatively produce the mRNA polymer with the ser and lysine residue in a small amount. For example in the stretch of polynucleotide UUU presence of one of the following codon UUA, UUG, CUU, CUC, CUA, CUG as well as UCU, UCC, UCA, UCG, and AGU can synthesize leucine and serine residues. (UUC)n can synthesize the polymer of phenylalanine, serine, and incorporation of few A and G will synthesize leucine. However, the presence of A, C, and G can also synthesize a small amount of tyrosine, isoleucine, and cysteine residue.
