Dec 01, 2016 · 95) Which of the following statements about the genetic code is FALSE? A) mRNA is read 3 bases at a time, which are called codons. B) Each codon is specific for only one amino acid. C) Each amino acid is coded for by only one codon. D) There are 3 termination codons that do not code for amino acids.
Jan 19, 2016 · 4. Which of the following statements about the genetic code is false A. Code is degenerate B. Based on nucleotide triplets C. Code is (nearly) universal D. Contains start and stop codons E. Code is unordered The genetic code is ordered: codons for the same amino acid are similar and codons for chemically related amino acids are similar.
Dec 14, 2020 · Nucleotides are always read in groups of three. some amino acid can be specified by more than one codon. Genetic code is almost universal, but not quite. For the above question, the statement which is false about genetic code is that every codon codes for one amino acid. Therefore, for the above question the correct answer is :Every codon codes for one amino acid.
The genetic code is redundant. c. All amino acids are specified by more than one codon. d. All codons specify an amino acid. Both a and b are correct answers. 19. Transposase is an enzyme that a removes incorrect nucleotides to repair; Question: 18. Which of the following statements about the genetic code is CORRECT? a.
c. germ-line cells. A geneticist examines the karyotype of a diploid cell from a particular species of frog and determines that 12 chromosomes are present. If a germ-line cell from this species divides by meiosis, then at the end of meiosis I each cell will have (Check all that apply.): a. 12 centromeres.
3 cells with 24 chromosomes and 1 cell with 22. b. 2 cells with 23 chr omosomes, 1 cell with 22, and 1 cell with 24.
1. During bacterial transformation, one or more traits of a cell are altered due to the uptake of DNA from the surrounding environment. 2. Avery, MacLeod, and McCarty were the first scientists to describe the process of bacterial transformation.
A cell biologist examines a diploid cell from a barley plant during prometaphase of mitosis and determines that 28 chromatids are present. The role of meiosis in this plant is to (Check all that apply): a. increase the number of chromosomes per cell from 14 to 28.
RNA synthesis makes an exact copy of the DNA molecule and protein synthesis makes a complementary copy of the RNA. c. RNA synthesis makes a complementary copy of the DNA using nucleic acid and protein synthesis requires the information in the RNA to be changed into a different type of molecule. d.
Functions of tRNA. It binds to an amino acid and is then "charged", it associates with mRNA molecules, and it interacts with ribosomes. The conformation of tRNA. results from base pairing (hydrogen bonding) within the molecule. 3' end is the amino acid attachment site (binds covalently). Anticodon.
RNA differs from DNA. usually a single polynucleotide strand, the sugar is ribose, and contains uracil (U) instead of thymine (T). Transfer RNA or tRNA. the adapter molecule, associates information in mRNA codons with specific amino acids. Functions of tRNA.
