For example A might match with Q, B with X, and so on. 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. Your IP: 167.71.255.154 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. 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. DNA replication requires that the complementary strands separate. Is all DNA replicated in the same manner? a. CTGCATAC GACGTATG b. GAAATTTC CTTTAAAG c. AGTCGAAT TCAGCTTA d. GCGTGCAC CGCACGTG e. GGATCCTG CCTAGGAC 1 See answer Answer 1.0 /5 0. jnalajohnson . 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. Draw a second water molecule on the figure above. -During DNA replication the two strand separate from one another and each strand has a new complementary strand built onto it. transcription occurs in the nucleus and translation occurs in the cytoplasm. Thanks Comments; Report Log in to … GCGTGCAC CGCACGTG. There are 3 H bonds between Guanine and Cytosine and 2 between Adenine and Thymine. The pilus is found on both donor and recipient cells. unidirectional transfer of both DNA strands. Which of the following is required to replicate the lagging strand of DNA? The function of the ribosome is to bind the tRNA molecules and then move them through the ribosome. You may need to download version 2.0 now from the Chrome Web Store. 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.

School Mercy College of Health Science; Course Title CHEMISTRY BIO CHEM; Type. True. 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. A new complementary strand is then synthesized onto each of the existing strands. Answered by Steven A.
