Hi I only know the first one and the last one
1. The three types of RNA are mRNA, rRNA, and tRNA. mRNA also known as messenger RNA carries instructions throughout the cell.rRNA also known as ribosomal RNA tells the amino acids to create protein. Last but not least, tRNA also known as transfer RNA, does the same thing as rRNA.
4. DNA influence physical traits by the genetic coding.
Hope this helps!! :)
