Choose any/all that apply to protein synthesis.Ribosomes aid in the formation of peptide bonds solely due to placing amino acids inproximity of one another, and in the proper orientation.The degeneracy of the genetic code is rather helpful, minimizing the harmful effects of manymutations.The 64 tRNA molecules are incredibly complex, with many features in common with oneanother yet with enough variability to perform the unique job that each must do.The ribosome reads mRNA in the 3'-5' direction, allowing the anticodon loops of tRNA tointeract in the proper orientation with the mRNA.Of all the metabolic processes we studied over this course, protein synthesis produces themost energy.

As per the central dogma of molecular biology, genetic information for protein synthesis is stored…

Which choice best fits the blank? Refer to picture. The ribosome moves along the mRNA strand. In panels b, c, and d, new tRNAs carrying ___________. match up with the codons of the mRNA strand. After each tRNA locks into place, a peptide bond forms between the amino acid the tRNA is carrying and the amino acid already there. This process repeats until the end of the sequence is reached. A. ProteinsB. NucleotidesC. Amino Acids
True or false Both pentose nucleic acid and deoxypentose nucleic acid contain the same pyrimidines Both pentose nucleic acid and deoxypentose nucleic acid and deoxypentose nucleic acid Contain the same purines RNA contains cytosine and thymine DNA and RNA are hydrolysed by weak alkali The anticodon of tRNA finds the complementary codon on mRNA The amino acid is attached to end of tRNA The amino acid is recognized by the anticodon of tRNA A given tRNA can be charged with only one particular amino acid
Choose a pentapeptied composed of five different amino acids. List the five amino acids. Present the messenger RNA codons for the amino acids and the sequence of the nucleotids on the DNA that was originally coded for the pentapeptide.
Hi, Could you please comfirm the following question. I have selected option c) because tRNA is the the complimentary pairs of mRNA so I figured the oppside end of the tRNA would be the same as the mRNA. When I have tired to double check my answer, no tutor has selected this answer. Thank you in advance, Like mRNA, tRNA has a ribose sugar, U instead of T, and is single stranded. Unlike mRNA, which remains a long single strand of nucleotides, tRNA folds so that some areas pair up. The resulting structure has an anticodon on one end and a site for an amino acid to attach on the other end. There is base complementarity (A pairs with U and G pairs with C) between an mRNA codon and tRNA anticodon.If the amino acid lysine attaches to a tRNA, which of the following anticodons could be at the opposite end of the tRNA molecule? a. UUU and UUC b. AGA and AGU c. AAA and AAG d. UCU and UCA
Below is a polinucleotide sequence of the non-template strand of a coding DNA sequence. Use the info of this molecule as well as the attached addendum to demonstrate the flow of genetic information to protein sequence as described by the so-called “Central Dogma” . Clearly indicate the direction of your polynucleotide strands and peptide/protein. Example: (USE SPACES BETWEEN CODONS): ' XXX XXX XXX XXX ' Example: (USE SPACES BETWEEN AMINOACIDS): Polypeptide: direction-XXX-XXX-XXX-direction ATG GCA TGC AAT AGC TCA TGC b) What would happen to the amino acid sequence if the underlined nucleotide (C) would change to an A?

One remarkable feature of the genetic code is that amino acids with similar chemical properties often have similar codons. thus codons with U or C as the second nucleotide tend to specify hydrophobic amino acids. Can you suggest a possible explanation for this phenomenon in terms of the early evolution of the protein-synthesis machinery?
RNA has many functions in a cell. Besides mRNA, which carries information from the genome to the translation machinery, and rRNA, which is part of ribosomes and catalyzes the formation of peptide bonds, name three other types of RNA and describe the function of each.
True or False. Just write T if it is true and F if it is false. In E. coli both RNA and protein synthesis take place in the cytoplasm. Okazaki fragments are ssDNA CHAINS OF 100-200 nucleotides long, primed by very short RNA primers in bacteria. In eukaryotic gene, the coding sequences are known as introns while the intervening sequences are the exons. The central dogma refers to the fact that proteins are products of information encoded in RNA using a DNA intermediate. The ends of the linear chromosomes are maintained by telomerase to prevent it from shortening during mitosis. The Shine Delgarno sequence is where the RNA pol binds during transcription in prokaryotes The sigma subunit of the E. coli RNA polymerase confers specificity to transcription. Both DNA replication and transcription follow a 5’ to 3’ direction of polarity. Nucleosomes are the structural unit of chromatin. In the lagging strand, the enzyme X removes RNA primers attached by PRIMASE and this gap is then filled…
A point mutation within the DNA sequence of a gene, which turns the codon UGU (codes for the amino acid cysteine) into the codon UGA would Question 47 options: build in another amino acid into the growing polypeptide chain at the ribosome build in the same amino acid (= cysteine) at the ribosome most likely lead to a stop of protein translation at the ribosome build in two amino acids into the growing polypeptide chain instead of one prevent the release of the amino acid from the tRNA in the P-site of the ribosome
Cystic fibrosis (CF) is an inherited disorder caused by different types of mutations, many of which prevent ions from moving across cell membranes. Normally there are channel proteins that allow passage of the ions, but in patients with one kind of CF these proteins seem odd. Closer examination shows that these proteins display the correct amino acid sequence. However, they fail to do their job. A) Given that the primary structure of the protein is correct, what can you infer about the DNA sequence for the gene coding this protein on this patient, is there a mutation? Explain. B) Why is the primary structure insufficient to guarantee the proper function of the protein?
What type of nucleic acid corresponds to the statement? CHOICES: Both ,DNA only, RNA only ,Neither can tolerate alkali hydrolysis found in the ucleus of eukaryotes carbonyl bonds control of protein synthesis have catalytic functions 3'-5' phosphodiester bond ester bond no OH in the sugar cytosine is equal to guanine part of central dogma gene expression susceptible to denaturation measured based on density of units bigger molecular size polynucleotide
Which of the following statements are correct? explain your answers.A. An individual ribosome can make only one type of protein.B. All mRNAs fold into particular three-dimensional structures that are required for their translation. C. the large and small subunits of an individual ribosome always stay together and never exchange partners.D. ribosomes are cytoplasmic organelles that are encapsulated by a single membrane.E. Because the two strands of DNA are complementary, the mRNA of a given gene can be synthesized using either strand as a template.F. An mRNA may contain the sequence ATTGACCCCGGTCAA.G. the amount of a protein present in a cell depends on its rate of synthesis, its catalytic activity, and its rate of degradation.
