Question

in nucleotides, the letters a, g, c, and t represent phosphate groups deoxyribose sugars nitrogen bases ribose sugars match the process with its purpose replication translation transcription to get the genetic instructions out of the nucleus for the ribosome to read the genetic instructions and make a protein to make sure a new cell has genetic code

Explanation:

• First question:
• In nucleotides (specifically in DNA), A (adenine), G (guanine), C (cytosine), and T (thymine) are the four nitrogen - containing bases. Phosphate groups are represented by the phosphate moiety in the nucleotide structure (not by these letters). Deoxyribose sugars are part of the nucleotide's sugar - phosphate backbone but are not represented by A, G, C, T. Ribose sugars are part of RNA nucleotides (and RNA has U instead of T).
• Second question:
• Transcription: It is the process where DNA is used as a template to synthesize mRNA. mRNA then moves out of the nucleus (in eukaryotes) so that the genetic information can be used for protein synthesis. So, "to get the genetic instructions out of the nucleus" matches with transcription.
• Translation: Occurs at the ribosome. The ribosome reads the mRNA (genetic instructions in the form of codons) and uses tRNA and amino acids to synthesize a protein. So, "for the ribosome to read the genetic instructions and make a protein" matches with translation.
• Replication: Ensures that when a cell divides, the new daughter cells receive an exact copy of the genetic code (DNA). So, "to make sure a new cell has genetic code" matches with replication.

Answer:

• First question: nitrogen bases
• Second question:
• "to get the genetic instructions out of the nucleus": transcription
• "for the ribosome to read the genetic instructions and make a protein": translation
• "to make sure a new cell has genetic code": replication
