How are nucleotides joined together? - ANSWER Condensation to form phosphodiester bond What is the function of mRNA? - ANSWER Carries genetic info out of nucleus Transcript translated to protein What is the function of tRNA? - ANSWER Carries aa to ribosome Anticodon pairs with codon on mRNA strand What is the function of rRNA? - ANSWER part of ribosome structure most abundant RNA coordinated coupling of tRNA to mRNA codons

How does translation terminate? - ️️-stop codon (UAA, UAG,UGA) -instead of tRNA, release factor binds to ribosome, causing hydrolysis of the peptidyl tRNA, releasing the completed protein -ribosome dissociates into its subunits, releasing mRNA, release factor, and tRNA mRNA and protein synthesis are very energetically - ️️adding each subunit requires the conversion of an NTP to an NMP, equivalent to hydrolyzing 2 ATPS to ADP -elongation step consume multiple ATP/GTP -splicing and ...

Holds the tRNA carrying the next amino acid to be added to the polypeptide chain. acid any substance that dissociates in water to increase the c...

BIO 1A03 McMaster University Test 2 Review Graded A+ Translation Cellular components are able to read the genetic message in mRNA and translate the message into specific primary amino acid sequence of a protein How does tRNA structure allow for SPECIFICTY in translation? 1. Plays critical role in ENABLING the translation of the information 2. Each type of tRNA molecule is not identical and can translate a specific codon into a specific amino acid What is the structure of tRNA? - single RNA str...

Degenerate - Answer A code in which a single element in one language is specified by more than one element in a second language. In other words, an amino acid may be specified by more than one codon. Aminoacyl tRNAs interact with mRNA - Answer Transfer RNAs base-pair with mRNA codons at a three-base sequence on the tRNA called the anticodon. The first base of the codon in mRNA (read in the 5′→3′ direction) pairs with the third base of the anticodon. Alignment of the two RNAs is antip...

Translation: What type of bond holds amino acids together? (NOTE that this is the bond formed during translation) peptide bonds Translation: In a tRNA molecule, where would you find the anticodon loop? 3' end of tRNA and cognate amino acid brought together by aminoacyl-tRNA synthetase enzymes (runs 5' to 3') Translation: What is the anticodon complementary to (what does it recognize)? a corresponding codon in a messenger RNA (mRNA) sequence Translation: What sp

Deoxyribonucleic acid (DNA) Correct Answer-A polymer of nucleotides conected via a phosphate-deoxyribose sugar backbone; the genetic material of cells and some viruses. Phosphodiester Bond Correct Answer-A type of covalent bond linking nucleotides together in a polynucleotide. Messenger RNA (mRNA) Correct Answer-An RNA molecule that contains the genetic information to encode one or more polypeptides. Transfer RNA (tRNA) Correct Answer-A small RNA molecule used in translation that posses...

Biology 1001 Final Exam Adam Hrincevich Questions and Answers Already Passed 1. **DNA's Hereditary Capacity**: Watson and Crick realized that DNA could encode a vast amount of hereditary information through its sequence of bases. 2. **DNA Strand Attachment**: The two polynucleotide chains in a DNA molecule are held together by hydrogen bonds formed between complementary bases. 3. **Inversions in Chromosomes**: Movements of DNA segments from one chromosome to another are not term...
