Question “help 7) In semiconservative DNA replication, each new double helix formed will have Atwo new strands…”
7) In semiconservative DNA replication, each new double helix formed will have Atwo new strands and two old strands. Bone new and one old strand in each helix C)three new strands in one helix and three old strands in the second helix D)two new and one old strand in one helix and two old and one new strand in the second helix E two new strands in one helix and two old strands in the other helix. 8) A gene is physically located on an) A chromosome. B) transfer RNA. C)enzyme. D)protein. Enuclens. 9) The function of transfer RNA is to Acany amino acids to ribosomes. B)transfer nucleotides to the nucleus. C)transmit coded information to the cytoplasm. D)turn DNA on and off. Eact as the site for protein synthesis. 10) Which type of RNA carries the genetic information from the nucleus to the ribosome? Aribosomal RNA B) transfer RNA C)messenger RNA D)All types of RNA can carry the information from the nucleus to the ribosome. 11) Which of the classes of RNA molecules has an anticodon? Aribosomal RNA B) transfer RNA C)messenger RNA D) primary RNA transcript Esbozyme 12) Prior to protein synthesis, the DNA A attracts tRNAs with appropriate amino acids. B serves as a template for the production of mRNA C)adheres to ribosomes for protein synthesis. D)contains anticodons that become codons. E must first undergo replication information in protein synthesis? 13) Which of the following describes Aprotein RNA-DNA B)DNARNA-protein CDNA-protein-RNA D)RNA+DNAprotein ERNA-protein-DNA DESPRE
Answer
7) B – One new and one older strand in every helix
- The nucleotide bases of the new strands that are formed from old strand templates will be complementary. Two daughter DNA molecules will be formed, each with one new strand and the same old strand. Other options are not available.
8) A) Chromosome
- It is an inheritance unit that is located at the locus of chromosomes and controls the expression of the trait. The nucleus is where the gene is located. It is therefore the best answer.
9) A: ribosomes and aminoacids-
- Specific aminoacids are carried by tRNA to ribosomes in order to synthesize polypeptides. Ribosomes are the site for protein synthesis.. The transcription promoter regulates the On and Off of DNA.
10) C) messenger RNA
- The cap methylated region of mRNA at the 5′ terminal is what makes it able to attach with the ribosome and thus transmit genetic information to its nucleus. All other options are therefore incorrect
- The above question covers all other functions of RNAs.
