This is a multi-selectquestion.DNA can be replicated.DNA can be repaired (since the message is redundant).DNA has a triplet code.The sugar-phosphate backbone is negatively charged, allowing the DNA to bewrapped around histones (forming structures called "nucleosomes").The hydrophobic bases of DNA are "hidden" so that the DNA will not beincorporated into the nuclear membrane.

If mutations occur in DNA, there are several mechanisms by which a cell can repair the defect. One method that can be used is nucleotide extision repair. All of the following characterize nucleotide excision repair, except: DNA ligase will replace the excised DNA and seal the backbone Enzymes can cleave the damaged region DNA can be opened to form a bubble so proteins can access the damaged DNA Can identify thymine dimers
"Unlike what happens in DNA replication, where both strands are copied, only one of the two strands is transcribed into MRNA. The DNA strand that contains the gene is sometimes called the sense strand, or coding strand, and the DNA strand that gets transcribed to give RNA is called the antisense strand, or noncoding strand. Because the sense strand and the antisense strand are complementary, and because the DNA antisense strand and the newly formed RNA strand are also complementary, the RNA molecule produced during transcription is a copy of the DNA sense strand... The only difference is that the RNA molecule has a U everywhere the DNA sense strand has a T." Consider the following segment of a DNA sense strand: (5') CAA-ACT-ACG-GCG-TTG-CAG (3’)
All the following statements about DNA are true, EXCEPT: O DNA is a double-helix, consisting of a sugar-phosphate backbone. O DNA is made up on nucleotides, which consist of one sugar, one phosphate, and one base. O DNA consists of 4 bases - adenine, uracil, cytosine, and guanine. The two main functions of DNA are to replicate itself and to create proteins (by providing the template for protein synthesis). O The sugar in DNA is deoxyribose.
Which of the following is NOT true of deoxyribonucleic acid (DNA)? Stores genetic information that can be expressed within a bacterial cell, transferred "vertically" to offspring cells, or "horizontally" to other recipient cells Serves as a template for the transcription of mRNA Each DNA nucleotide contains the sugar ribose, phosphate, and one of the following nitrogenous bases: adenine, uracil, guanine, or cytosine Found as a circular molecule in bacteria, either as chromosomes or plasmids None of the other four answers (all are true of DNA)
Below is the 5’–3’ strand of a double-stranded DNA molecule with the following nucleotidesequences (all belong to an exon):5’ C C T A T G C A G T G G C C A T A T T C C A A A G C A T A G C 3’ 1. If the above DNA strand is the template (antisense) strand and the DNA molecule is transcribed that produced a functional mRNA. Assuming there are no mutations, the said mRNA is then brought to the site of protein synthesis,a. what would be the amino acid sequence of the synthesized polypeptide chain?b. how many possible kinds of tRNA molecule that will bring the 2nd amino acid observing wobble hypothesis? List down their anticodons.
Protein synthesis is a complicated process involving DNA being transcribed to RNA, which is then translated into amino acids. Complete the DNA-to-amino acid table for three consecutive codons with the appropriate nucleotides and amino acids using a codon table. Nucleotide and amino acid options can be used multiple times or not at all. 5' to 3' DNA strand 3' to 5' DNA strand transcribed mRNA tRNA anticodon amino acid arginine cysteine leucine T A U A T G A U arginine leucine A proline T A U Answer Bank A G G с с T T A A U glutamic acid U G C G с с glutamic acid G G G с с G C arginine C G с G
Which of the following statements is false of ligase? Ligase is specific to leading strand synthesis. Ligase is responsible for the formation of phosphodiester bonds. Ligase is an ATP-dependent enzyme. O Ligase is essential to replication.
determine what amino acid will be formed from the given DNA strand below: 3’ T A C A T G C C G A A T G C C 5’ Note: Prepare the partner strand of this DNA. Discuss how will replication happen by mentioning the enzyme needed then transcribe to form mRNA. Discuss what will happen to mRNA, then translate, mentioning the anticodon to be used. Look at the genetic code to know what amino acid will become part of the polypeptide chain. 1. Partner DNA strand 2. the mRNA strand 3. the tRNA 4. the formed amino acids 5. the discussion of the entire procedure
What is one possible DNA strand that would produce the following amino acid sequence? (Do NOT include any spaces) Histidine-Tryptophan-Lysine
Background: DNA nucleotides (i.e A, T, G, and C) are naturally found in a paired, or bonded, arrangement (i.e. the double helix) within the nucleus of every cell. This structure makes the process of replication that occurs prior to mitosis and meiosis very reliable. The purpose of DNA, though, is not simply to make copies of itself, but to provide a set of instructions for the synthesis or "construction" of biomolecules, such as proteins. Why is transcription (i.e. the formation of an RNA copy of a given gene) a necessary step in the "construction" process highlighted above? What is the cell looking to ultimately do with this RNA information?
Match each of the following terms with the one definition that best describes it. Any of the following: Uracil, Cytosine, Thymine, Adenine, Guanine ····· Closes "nicks" between DNA fragments, forming a covalent bond that joins the fragments together Lays down a short chain of nucleotides at the beginning of DNA replication Synthesizes mRNA from a DNA template Unwinds the DNA double helix during DNA replication Adds individual nucleotides to a growing DNA strand during DNA replication 1. RNA Polymerase 2. DNA Polymerase 3. Ligase 4. Primase 5. Helicase 6. Nitrogenous Base
Which of the following statements is TRUE of BOTH DNA replication and DNA transcription? During the process, the DNA double helix is separated into single-stranded regions. An intermediate in the process is an RNA-DNA hybrid helix. During the process, only one single-stranded DNA region acts as a template. Amino acids are matched to a strand of DNA to form a new polymer.
