Protein Synthesis Test

Master protein synthesis! Explore DNA, RNA, genes, and mutations in this biology quiz.

What determines the traits of an organism? relation of AT to CG base pair number of nitrogen bases in RNA presence of ribose or deoxyribose in a nucleic acid sequence of nitrogen bases in DNA Instructions found in DNA control a less specialized cell’s potential to change in size, shape, and function. The process which controls the future of a cell is -- Cell transformation Cell differentiation RNA translation DNA transcription How does a stem cell become a nerve cell, bone cell, or muscle cell? by expressing certain combinations of genes by repressing certain combinations of genes by expressing certain combinations of genes and repressing others by expressing all genes When one or more nucleotides are lost during chromosomal crossover in meiosis, this is called-- deletion mutation insertion mutation substitution mutation gene duplication What is the purpose of this process? converting a RNA code into genes converting genes into proteins reconstruction of the DNA molecule converting DNA into a ribosome Cell mutations with a DNA sequence are--- unnatural events that are harmful to genetic diversity unnatural events that always affect the phenotype natural events that produce genetic diversity in organisms natural events that always affect the phenotype DNA provides a very significant role in the formation and development of an organism. What is this role? encodes information Provides protection from disease produces food material releases energy A linear code of 3 sequential bases on one side of a DNA molecule is a? base pair codon amino acid gene When one or more bases are changed in DNA it's called a? transgenic shift monohybrid trait single genotype mutation What is the role that ribosomes play in the production of proteins? takes the code from the DNA molecule and creates genes takes the code from the mRNA molecule and creates proteins matches DNA to tRNA replicates the DNA What process results in two complete strands of DNA from one original strand? DNA replication mRNA transcription DNA translation DNA transformation Which of the following is NOT true for DNA? made of repeating subunits called nucleotides contains codes for your genes contains adenine, thymine, guanine, and cytosine regenerates itself right after a cell divides into new cells What part of protein synthesis does this diagram represent? mRNA tRNA rRNA DNA What is the structure that is labeled E? amino acid codon anticodon polypeptide Refer to the chart. What type of organism do the triplet codes found in this chart apply to humans only plants and animals prokaryotes all living things Which of the following is a true statement in regard to the genetic code? The genetic code gives us no information about the changes that occur between species The genetic code is considered a universal code, suggesting that there is a single evolutionary history that underlies the origin of all organisms The genetic code is consistent in biotic and abiotic factors in an environment The genetic code varies greatly between species Where in the cell are the nucleic acids stored? 6 2 4 5 James Watson and Francis Crick first discovered the structure of the DNA molecule in 1953. They discovered that the molecule has a shape specific to just that molecule. That shape can best be described as - a single strand containing 4 different bases that vary depending on the type of DNA ladder shaped, containing 5 nitrogenous bases that bond to one another triple stranded, with bonds between each strand holding the three strands together double stranded and twisted, with a base bonded to another holding the strands together Which of the following are the components of a nucleotides? phosphate, sugar, amino acids amino acids, nitrogen base, sugar phosphate, sugar, nitrogen base amino acid, nitrogen base, sugar Why do frameshift mutations have a greater effect on protein synthesis than a point mutation? They don't the point mutation has a much greater effect on the protein being produced Everything after the mutation is affected by the mutation They both have the same effect on the protein produced The frameshift will only change one amino acid
