The DNA components shown in the Gizmo are phosphate molecules and deoxyribose sugars 2. A nucleoside has two parts: a pentagonal sugar (deoxyribose) and a nitrogenous base (in color). When a nucleoside is joined to a phosphate, it is called a nucleotide. How many different nitrogenous bases do you see? 4 Note: The names of these nitrogenous bases are adenine (red), cytosine (yellow), guanine (blue), and thymine (green).
Due to the strict pairing of nitrogen bases in DNA molecules, the two strands are said to be ____________________ to each other. 25. The process by which DNA copies itself is called ____________________. 26. The enzyme that is responsible for replicating molecules of DNA by attaching complementary bases in the correct sequence is called ____________________ ____________________.
Consider the following DNA sequence found on a different portion of the coding strand of Henry's CYP2C9 gene: TTACCGAGA a. What would be the sequence of the template strand on this portion of the gene? b. How many triplet codes does this DNA sequence contain? c. What would be the sequence of the mRNA after this sequence is transcribed?
LEU 6. In Henry’s other CYP2C9 gene, the 430th nucleotide had changed from a cytosine (C) to a thymine (T). This mutation converts a CGT triplet code in the coding strand of the DNA molecule to TGT. Beginning with this triplet code on the DNA, describe the effect that this change would have on the following: a. The nucleotide sequence on the template strand of the gene.
The bases used in DNA replication are adenine (A), thymine (T), guanine (G), and cytosine (C). In RNA, uracil (U) is used instead of thymine, but in this case, that is irrelevant. Generally, in a normal human being, A is matched up with T, and G is matched up with C to makeup the complementary base pairs. An important step in the initiation of the replication process is the binding of the RNA primase. This primase attracts the nucleotides that bind to the corresponding nucleotides of the 3’-5’ strand.
Associate Program Material DNA Worksheet Answer the following in at least 100 words: Describe the structure of DNA DNA structure consists of a polymer that is made up of subunits called nucleotides. DNA looks like a spiral staircase this is a double helix. Each spiral strand is created from sugar phosphate and any attached bases, when the strands line up and connect the bases also match up. DNA consists of many different nucleobases named adenine, thymine, guanine and cytosine. Only two of these will connect those two are adenine and thymine the other two guanine and cytosine won’t How does an organism’s genotype determine its phenotype?
Explain how DNA replicates? What are some characteristics of the structure of DNA? Explain complementary base pairing. 15. Describe in detail the phases of mitosis.
Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating (.
