For example A might match with Q, B with X, and so on. If the original strand did not uncoil then, even if synthesis was possible, the two new molecules would be hopelessly entangled. kaypeeoh72z learned from this answer Answer: a. CTGCATAC GACGTATG. Pages 11 Ratings 83% (6) 5 out of 6 people found this document helpful; This preview shows page 7 - 10 out of 11 pages. Which of the following DNA molecules is the most stable? Which of the following DNA molecules is the most stable? Only one strand codes for proteins at any given point in the molecule. Doubled-stranded DNA consists of two antiparallel strands, meaning that one strand is oriented in the 5' to 3' direction, while the other is oriented in the 3' to 5' direction. Only one strand is used to transcribe mRNA. You may need to download version 2.0 now from the Chrome Web Store. unidirectional transfer of both DNA strands. Asymmetrical spacing of the backbones of the DNA double helix generates major and minor grooves. © 2003-2020 Chegg Inc. All rights reserved. However DNA is organized differently in different organisms. GCGTGCAC CGCACGTG. Therefore the base sequence on one strand determines the complementary sequence on the other strand. The large ribosomal subunit joins the translation initiation complex after the small subunit has already joined. The correct structure of DNA components can be presented as. If we were to write a normal English word the complementary sequence would be determined by the letters in that word and could not be changed. View desktop site, Answer to 1: as there are no options of DNA molecules given, it is suggestive that the one with most numbers of G triple bond C present will be the most stable and strongest among others. As a result, they attract each other. a. CTGCATAC GACGTATG b. GAAATTTC CTTTAAAG c. AGTCGAAT TCAGCTTA d. GCGTGCAC CGCACGTG e. GGATCCTG CCTAGGAC 1 See answer Answer 1.0 /5 0. jnalajohnson . The transcription enzyme first attaches to the ________ of the gene. Plasmids are small pieces of DNA that may carry genetic information for antibiotic resistance. 5'-GAAATTTC-3' 3'-CTTTAAAG-5' C. 5'-AGTCGAAT-3' 3'-TCAGCTTA-5' D. 5'-GCGTGCAC-3' 3'-CGCACGTG-5' E. 5'-GGATCCTG-3' 3'-CCTAGGAC-5' Expert Answer 100% (1 rating) Previous question Next question Get more help from Chegg . Performance & security by Cloudflare, Please complete the security check to access. Which of the following DNA molecules is the most stable? The enzyme that accomplishes transcription is termed. DNA is a two stranded molecule. Genes may be transferred in three different ways. True. • Biology tutor 21154 Views a messenger RNA molecule synthesized from the DNA molecule in the nucleus. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Which of the following molecules is the most stable A mRNA B hemoglobin C. Which of the following molecules is the most stable a. Asymmetrical spacing of the backbones of the DNA double helix generates major and minor grooves. A new complementary strand is then synthesized onto each of the existing strands. the blueprint of the RNA molecule used to bind amino acids together to form proteins. A certain polypeptide is 100 amino acids in length. Finally the two strands for each new molecule attach and coil up. Which of the following is a characteristic of double-stranded DNA? As well as this there are hydrogen bonds between the bases and surrounding water molecules, and this combined with the even stronger phosphodiester bonds in the sugar phosphate backbone make DNA very stable. A structural gene encodes the information for a specific protein. DNA replication requires that the complementary strands separate. -During DNA replication the two strand separate from one another and each strand has a new complementary strand built onto it. To allow simultaneous replication of the leading and lagging strands by dimeric DNA pol III, the DNA of the leading strand has to be folded. True. The function of the ribosome is to bind the tRNA molecules and then move them through the ribosome. Which of the following DNA molecules is the most stable? Are both strands of DNA used in making RNA? Asymmetrical spacing of the backbones of the DNA double helix generates major and minor grooves. In DNA synthesis events occur in the following order, a portion of the original molecule uncoils and the two strands separate in that region. | True. There are 3 H bonds between Guanine and Cytosine and 2 between Adenine and Thymine. Your IP: 188.8.131.52 [Total 3 marks] 2. If one donor cell is mixed with 20 recipient cells, eventually ________ cells will become donors. Ponds provide a very stable environment for aquatic organisms. During translation of this polypeptide, how many amino acids entered through the A site of the ribosome? • Doubled-stranded DNA consists of two antiparallel strands, meaning that one strand is oriented in the 5' to 3' direction, while the other is oriented in the 3' to 5' direction. Which of the following is required to replicate the lagging strand of DNA? Three properties of water that The terminator of a gene is located upstream of the coding region. GCGTGCAC CGCACGTG. Elongation of the polypeptide chain is terminated when a stop codon enters the P site of the ribosome. -direct contact between donor and recipient cells, During bacterial conjugation, plasmid replication occurs in. Cloudflare Ray ID: 5f0e75150cfc15af But for any given mRNA strand only one of the DNA strands is used.The complementary nature of DNA would make it very unlikely that both strands could code simultaneously for functional proteins. The key event in protein synthesis is the formation of bonds between adjacent amino acids in the protein and the breaking of bonds between the same amino acids and the tRNA molecules that first bring the amino acids to the ribosomes. After DNA replication two identical DNA molecules are formed. Then DNA polymerase synthesizes complementary strands. the tRNA that was in the A site moves into the P site. T/F. Which of the following DNA molecules is the most stable? How is protein synthesis similar to the catalysis of a reaction by an enzyme? Is all DNA replicated in the same manner? The products of protein synthesis are exclusively enzymes and enzyme products. -DNA is synthesized by the enzyme DNA polymerase. -Is to store and transmit genetic information. A. The primary function of DNA, and why does a DNA molecule consist of two strands. how is bacterial conjugation like as sex in eukaryotes? Assessment. The pilus is found on both donor and recipient cells. True. However, both strands are used during DNA replication. Water molecules are polar. One DNA strand is used as the template to make two new strands of DNA. Doubled-stranded DNA consists of two antiparallel strands, meaning that one strand is oriented in the 5' to 3' direction, while the other is oriented in the 3' to 5' direction. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. School Mercy College of Health Science; Course Title CHEMISTRY BIO CHEM; Type. With its double-helix structure, DNA is coiled like a spring. Sometimes a piece of bacterial DNA near the specific site of insertion stays attached to the phage DNA, and a piece of phage DNA remains behind. Each of the four bases in DNA (adenine, thymine, guanine, and cytosine) binds to a unique complementary base on the other strand. Your drawing should show: • The bond(s) between the two molecules • The name of the bond • The charges on each atom. GCGTGCAC CGCACGTG 56. Doubled-stranded DNA consists of two antiparallel strands, meaning that one strand is oriented in the 5' to 3' direction, while the other is oriented in the 3' to 5' direction. 5'-CTGCATAC-3' 3'-GACGTATG-5' B. Which of the following does occur during bacterial conjugation? G and C are. During transcription the two strands separate and RNA polymerase synthesizes mRNA based on the sequence of one the two strands.
