Thousand of gene are encoded on the lenghth of DNA which after condensation form chromosome and adjust in the nucleus of the cell.
Describe how the information that makes up a gene is stored along a length of dna.
17-11. Methylation of eukaryotic DNA controls gene expression. a) Describe in words the control of methylation of DNA in eukaryotes. b) Describe in words how silencing starts with methylation.

Describe how homologous recombination can change DNA sequences by gene conversion vs. how it can cause deletions/insertions.
The first level of gene regulation occurs along the chromosome, through chemical modifications of the DNA or histones. How do these chemical modifications cause changes in gene expression? Select all that apply a. The chemical modifications to DNA could prevent the removal of introns from the mRNA b. The chemical modifications to DNA could activates enzymes that add chemical modifications to histones c. The chemicalodifications to DNA and histones could affect the binding of ribsomea to mRNA to initiate translation...

(1 pt) The protein coded for by Gene Y is 100 amino acids in length. How many base pairs are in Gene Y2 (1 pt) How many codons would be in Gene Y? (1 pt) Gene Z is 360 base pairs in length. How many amino acids are in...
The following sentences describe chromatin structure and how altering chromatin structure can affect gene expression. Complete each sentence using the words provided.In some cells, DNA combines with proteins to form a substance calledThe lowest level of chromatin structure consists of DNA wrapped twice around a group of histones to form a(n)The formation of nucleosomes may block the binding of transcription factors and RNA polymerase II to theThe structure of chromatin can be modified by altering either the DNA or the...
In a eukaryotic cell, if DNA is stored in the nucleus and protein synthesis occurs in the cytoplasm, then how does the information in DNA become functional (i.e. processed into protein)?
III. Subclone the gene into plasmid, extract the plasmid DNA. 5. You know that your insert (gene of interest, GOI) is flanked by the EcoRI sites, which makes this restriction enzyme a perfect candidate to cut out your gene. You also know that the GOI has a unique BamH1 restriction site. After subcloning the PCR product into the plasmid, a purified DNA preparation of the plasmid is digested to completion with BamHI restriction endonuclease. In separate reactions, the same preparation...
Briefly describe the structure of RNA. What makes it different than DNA? What do DNA and RNA stand for? What are their roles? What are the DNA base pairing rules? What are the RNA base pairing rules? Describe what the following abbreviations stand for (ACGTU). What is the “norm” for lactose digestion in adults? Why are some people lactose intolerant? Is lactose tolerance relatively recent or ancient?
Briefly describe the difference between the mass of a DNA sample and the length of a DNA molecule, and give the most common unit of measurement for each.
