Dna contains instructions for making the different moecules that a cell needs to grow and grow for example, is made by

a. a protein, translating mrna
b. mrna, transcribing proteins
c. mrna, translating dna
d. a protein, transcribing mrna

dna contains instructions for making the different molecules that a cell needs to grow and grow for example, Protein is made by translating mRNA.

Explanation:

Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA genetic information and assembles the new polypeptide chain.  tRNA translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer free amino acid from the cytoplasm to the ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.

answer: 21

step-by-step explanation:

divide 630 by 30. 30 goes into 630 21 times

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
