Double stranded dna - Study guides, Class notes & Summaries

Heat can be used to separate two strands of double-stranded DNA, with the least amount of heat necessary to separate strands with the fewest and weakest bonds holding them together. Consider the following double-stranded DNA sequences that each consist of 10 bp. Which sequence will likely require the least amount of heat for separation?

TEST BANK FOR BAILEY AND SCOTT'S DIAGNOSTIC MICROBIOLOGY 14TH EDITION BY TILLE REVISED 2024 1.A DNA sequence that encodes for a specific product (ribonucleic acid [RNA] or protein) is defined as a: 2.Pieces of deoxyribonucleic acid (DNA) that move from one genetic element to another and contain genes for movement and genes for other features are called: 3.Miniature chromosomes composed of several genes in double-stranded, closed, circular structures are called:

Compared with cellular genomes, viral genomes: A. are larger, with more base pairs. B. are smaller, with fewer base pairs. C. have genomes composed of RNA only. D. also must have double-stranded DNA as their genome. Correct Answer-B. are smaller, with fewer base pairs. Consider a mutation in which the change is from the codon UCU which encodes serine, to ACU which encodes threonine. Which type of point mutation is this? A. nonsense mutation B. frameshift mutation C. silent mutation D....

7Q1-Describe the double helix nature of DNA. Why is it that DNA is always found as a double stranded, antiparallel and complementary molecule? Correct Answer-The two strands of DNA run in anti-parallel directions and attached to each sugar is one of four types of nitrogenous bases, which make hydrogen bonds. It is antiparallel and complementary so that it has two copies as a safety measure. 7Q2-What are histones and the structural components(DNA/proteins)of a nucleosome? Correct Answer-Histon...

BIOLOGY AQA AS 74011 PAPER 1 [WELL VERIFIED] • The human cell then makes a complementary strand to the HIV DNA. The complementary strand is made in the same way as a new complementary strand is made during semi-conservative replication of human DNA. Describe how the complementary strand of HIV DNA is made. - ANS---- there are complementary nucleotides/bases pair - DNA polymerase used - Nucleotides join together (to form new strand)/phosphodiester bonds form; Contrast the structures of ...
