It is one of the two types of nucleic acids other being RNA. Which of the following events is associated with the breakdown of that food particle. B The sequence of amino acid in a histone tail is altered during chromatin remodeling.

Genomes are encased within a capsid. The initial step in unwinding dna double helix is accomplished by the initiation complex. DNA contains the instructions to make proteins.

During DNA methylation a methyl group is added to a C O c. DNA replication proceeds in one direction around the bacterial chromosome. The bases are on the outside of the helix.

Which of the following is FALSE when comparing RNA and DNA. DNA usually has two polynucleotide strands whereas RNA usually has one strand. DNA uses the nitrogenous base uracil.

The leading strand of DNA is made continuously. All DNA encodes genes D. DNA has thymine and RNA has uracil DNA is a nucleic acid and RNA is an amino acid DNA uses deoxyribose and RNA used ribose in the backbone DNA is double stranded and RNA is single stranded QUESTION 2 In a DNA double helix nucleotides on complementary strands are held.

Both are composed of a phosphate group a pentose sugar and a nitrogenous base. The backbone contains alternating ribose sugar and phosphate groups. Two copies of each type of histone.

Which of the following statements about DNA gel electrophoresis is false. Latent DNA virus infections occur when the DNA genome is destroyed by the cells immune response b. They do not alter the DNA sequence itself.

C A nucleosome is composed of 8 histone proteins. Both are composed of phosphate groups. DNA has thymine whereas RNA has uracil.

Chargaff showed that adenine and thymine were found in equal percentages in DNA but he did not know this was because of base-pairingThis answer is correct. Which of the following is FALSE about the differences between DNA and RNA. Human genome contains 30000 - 40000 genes B.

The helix has two grooves called the major groove and the minor groove. The base to be methylated is found in the pattern CpG O b. Which of the following is false about the replication of dna.

DNA uses the nitrogenous base thymine. DNA profiling allows suspects to be identified on the basis of genetic material. Over a given period of time smaller DNA fragments migrate further into the gel.

Which structure is the site of the synthesis of proteins that may be exported from the cell quizlet. Which of the following statements is false regarding DNA viral genomes. Which one of the following statements about nucleosomes is false.

Because the two strands of parental DNA run in opposite directions the new strand must be made In different way. Genomes can be single and double stranded. DNA is found in a cells nucleus.

Genome sizes vary from one virus to another. In DNA A pairs with T whereas in RNA A pairs with U. DNA is a polymer made up of monomeric units called nucleotidesThere are four different nucleotides.

Both are composed of sugars. The lagging strand of DNA is started by an RNA primer. B In a DNA molecule adenine bonds to thymine and guanine to cytosine.

Epigenetic changes result from modifications of the DNA that affect nucleosome spacing and therefore transcription. One DNA molecule can include four different nucleotides in its structure. DNA does not have a hydroxyl group at 2 RNA has a hydroxyl group at 2 DNA uses a 6 carbon sugar base while RNA uses a 5 carbon sugar base DNA is the template for RNA RNA can be the template for cDNA RNA uses uracil instead of thymine as a nitrogenous base DNA is double stranded while RNA is This problem has been solved.

A The DNA double helix wraps around the nucleosome. Where is a bacterial cells DNA found. Which of the following is false about DNA structure.

A The DNA molecule has a uniform diameter. Both are produced by phosphodiester linkages. Formation of a holoenzyme unwinding of the dna during transcription is the result of the activity of a helicase enzyme downstream of the rna polymerase.

Any base pair cannot pair with any other base Adenine pairs with thymine and cytosine pairs with guanine. Which structure is the site of protein synthesis in the cell. D DNA contains the nitrogenous base uracil.

Which of the following statements is false. Genomes are always linear. What changes can occur to the DNA and to the histones that will impact gene expression.

DNA had a deoxyribose sugar whereas RNA has ribose sugar. DNA is made up of units called nucleotides. Daughter double helices are generated behind a moving replication fork.

The statement that is false regarding DNA is that DNA uses the nitrogenous base uracil. Which statement about DNA replication is false. B DNA molecules have a sugar-phosphate backbone.
