Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
You head into a eukaryotic cell. Ms. Frizzle turns to you and says: "Gene expression is essential to keeping a cell alive. I want to see either transcription OR translation up close! Please pick one. Tell me where we should go to see it happening, and describe what we will see when we get there!"
Step by step
Solved in 4 steps
- Describe and explain (step by step) how DNA is Transcribed into mRNA. Then describe and explain (step by step) how mRNA is Translated into proteins. Be sure to describe where these events are occurring, which structures are involved and be as detailed as you can.Translation occurs within the cell's _____________ and employs _____________ to manufacture _____________. Question 8 options: nucleus; the coding sequence of a gene; mRNA nucleus; ribosomes and a gene; tRNA cytoplasm; the coding sequence of a gene; mRNA cytoplasm; mRNA; proteins nucleus; mRNA; proteinsThe information in DNA is used by cells to produce proteins that perform various functions in cells. The process of gene expression involves the transcription of a mRNA molecule that is translated by ribosomes into a strand of amino acids.1. Use your DNA strand to construct a part of a messenger RNA molecule.DNA: A G T A C C G G G C A A A C T G C A T T G T GmRNA:2. find it by searching the internet for the "Genetic Code Chart" to determine the sequence of amino acids in your polypeptide chain. Remember to START translation at the start codon by adding a Methionine and STOP translating when you reach a stop codon.
- Occurring in the nucleus ribosome mitochondrion , translation transcription is the process of making an RNA copy from a DNA template. The molecule then enters the cytoplasm. The process in which the mRNA sequence is converted into a sequence of amino acids is called translation transcription . In the cytoplasm, the nucleus ribosome mitochondrion reads the amino acid sequence and assembles the protein.The sequence below is an mRNA strand that is in the cytoplasm ready to translated by a ribosome. If the gene that codes for this mRNA mutated so that the codon in the red box became CUG.

- The following sequence is the coding strand of a piece of DNA. Type out the corresponding template strand of DNA and the MRNA that could be made from this piece of DNA if you assume that transcription begins at the first nucleotide listed. Next, use the attached genetic code table to translate the mRNA into a polypeptide that could be made from the message and list that sequence along with those of the DNA and MRNA.

The genetic message to make a specific amino acid in a protein, is carried by a specific three nucleotide unit on the messenger RNA called a During transcription, the nitrogen base adenine on the DNA bonds with the nitrogen base ______________ on the messenger RNA. The enzyme __________________ unwinds the DNA double helix in DNA transcription.Cystic Fibrosis is a genetically heritable disease caused by the loss of the chloride channel, CFTR. Studies of this gene have found that the Gene includes 250,000bp in the DNA. Scientists found that the mRNA had 6,500 nucleotides, and the final protein had 1480 amino acids. How much of the mRNA is untranslated? How much of the RNA that is produced does not leave the nucleus? One of the mutations that results in a disease phenotype can be easily identified because the mutation results in a much longer mRNA then normal. Where would you look for this mutation? What might this mutation have affected?
