40 POINTS FOR WHO EVER CAN HELP ME

Questions
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?

Answer 1

1) Three major types of RNA are mRNA, or messengerRNA, 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.

3) In 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 influences your genotype but your phenotype is the dominant trait from the genes.

Answer 2

1. mRNA transcribes the genetic code from DNA into a form that can be read and used to make proteins. mRNA carries genetic information from the nucleus to the cytoplasm of a cell, rRNA is located in the cytoplasm of a cell, where ribosomes are found. rRNA directs the translation of mRNA into proteins, Like rRNA, tRNA is located in the cellular cytoplasm and is involved in protein synthesis. Transfer RNA brings or transfers amino acids to the ribosome that correspond to each three-nucleotide codon of rRNA. The amino acids then can be joined together and processed to make polypeptides and proteins.
2. Transcription is the process of DNA being copied.

4. Genetics have a huge roll to play in the link between DNA and traits.
