Nucleotides in DNA pair via:     ionic bonds     hydrogen bonds     covalent  bonds     None of the answers are correct.   Suppose you are analyzing a nucleic acid sequence that contains guanine, cytosine, adenine, and uracil nucleotides.  What type of nucleic acid could this be?  Select all that apply.     mRNA     tRNA     DNA     rRNA

Choose a pentapeptied composed of five different amino acids.  List the five amino acids.     Present the messenger RNA codons for the amino acids and the sequence of the nucleotids on the DNA that was originally coded for the pentapeptide.

A nucleotide is the monomeric building block of the polymer of DNA. To better understand the characteristics of DNA, it is important to understand how the monomers join to form the polymer. Use the following diagram of DNA (and the diagram of a nucleotide in the PowerPoint presentation) to label the listed features: 3' and 5' ends, nucleotide, phosphate group, sugar group, phosphodiester bond, nitrogenous base (pyrimidine and purine), and hydrogen bonds. NHZ NH2 HN OH₂N NH₂ 5. Looking at the polymer, why is a DNA considered antiparallel? 6. Why are the ends of DNA strands named 3' or 5'? 7. How do A:T interactions differ compared to G:C interactions? How does this affect stability of the bond pairs? 8. During gel electrophoresis, to which electrode (+ or -) does DNA migrate? Why?

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 T T A G A G 3' to 5' DNA strand A A T C T C G C G transcribed mRNA U U A G A G C G C TRNA anticodon A. A U C U G C G amino acid leucine glutamic acid Answer Bank A glutamic acid leucine cysteine arginine proline U

A molecule has the following percentages of bases: A= 42%, C = 14%, G= 21% and T=23%. Which of the following molecules best fits the description? Group of answer choices 1.Double-stranded RNA 2. Single-stranded DNA 3. Single-stranded RNA 4. Double-stranded DNA

Draw a generalized nucleotide. Just put “base” instead of drawing the actual base. Label the carbons 1 through 5.

The sequence of coding strand of a DNA molecule is given below. Assume that it is read from left to right. ССТАССТТАТGCСАAGTTGGGGATАААСТС The left end of this molecule is the end. How many amino acids will be in the protein translated from this sequence? What is the name (not abbreviation) of the fourth amino acid in the protein translated from this sequence? The label on the end of the protein that is translated first is th v end. 5' Please answer all parts of the question. carboxyl 3' amino

If you were asked to build a model of a nucleotide, what structures would you need to represent in the model? CHECK ALL THAT COULD APPLY Group of answer choices five carbon sugar ribose sugar phosphate group methyl group codon base

It asks to categorize the possible answers to a component of eukrayotic RNA, eukrayotic DNA or both:
