Answers:-Ribosomal RNA (rRNA) is a component of ribosomes. Carries out the synthesis of proteins. -Messenger RNA (mRNA) carry genetic information from genes to the ribosome, where the corresponding proteins can be synthesized. -Transfer RNA (tRNA) translate the information in mRNA into a sequence of amino acids.
Answers:mRNA = messenger RNA; these are gene transcripts that will be translated into a protein product tRNA = transfer RNA; different tRNAs carry different amino acids that will be used by the ribosome during translation. their purpose is to serve as an interface between codons and the amino acids rRNA = ribosomal RNA; ribosomes are composed of a large amount of RNA and rRNA is a blanket term for any RNA in ribosomes DNA must be able to replicate itself because DNA is the storage medium of the information of how to create proteins. Without DNA replication a cell cannot reproduce because it has no blueprints to make all of the cellular components.
Answers:mRNA: mRNA is transcribed from a DNA template, and carries coding information to the sites of protein synthesis: the ribosomes. Here, the nucleic acid polymer is translated into a polymer of amino acids: a protein. tRNA: transfers a specific amino acid to a growing polypeptide chain at the ribosomal site of protein synthesis during translation. Basically forms the protein. rRNA: provide a mechanism for decoding mRNA into amino acids and to interact with the tRNAs during translation by providing peptidyl transferase activity. Basically acts as a coordinator for the actions of mRNA and tRNA.
Answers:Three types of RNA required for translation: 1. Messenger RNA- this is a "mirror image" of the DNA encoding the amino acid sequence for the protein specified by the gene. 2. Transfer RNA- This is an RNA molecule that "activates" the amino acid and recognizes the codon specifiying that amino acid in the mRNA sequence. 3. Ribosomal RNA- this is probably RNA that has a structural role in a complex called the ribosome, the "machine" that actually joins amino acids together to make proteins.
