20 points if anyone can
1. describe the structure and function of each of the three types of rna.
2. describe the processes of transcription.
3. describe the process of translation.
4. how does dna influence physical traits?

1.Three major types of RNA are mRNA, or messenger RNA, that serve as temporary copies of the information found in DNA; rRNA, or ribosomal RNA, that serve as structural components of protein-making structures known as ribosomes; and finally, tRNA, or transfer RNA, that ferry amino acids to the ribosome to be assembled 
2.Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.
3.n molecular biology and genetics, translation is the process in which ribosomes in a cell's cytoplasm create proteins, following transcription of DNA to RNA in the cell's nucleus. ... In translation, messenger RNA (mRNA) is decoded by a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide.
4.DNA is the genetic holder in our body ! for any message DNA has to convert in RNA and then protein resulting in all the traits we have !
so on transcription DNA information is converted to RNA and during translation into protein thus these protein helps in building our appearance , our Personalities every thing !

so we can say DNA influence physical trait !

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature
