BIO 240 Week 3 DNA and Protein Synthesis

Answer the following questions, in a total of 500 to 700 words.

– Describe the structure of DNA and the steps of protein synthesis.

– Describe the relationships between the following terms:

– DNA

– Chromatin material

– Gene

– Chromosome

– Use the following gene in protein synthesis:

TAGGACCATTTTAGCCCC

– Show the mRNA.

– Show the tRNA.

– Name the amino acids that will be placed in the polypeptide chain. (Use the codon table in Ch. 17 of Campbell Biology.)

– A gene will direct the making of polypeptide chains, and polypeptide chains form proteins. All enzymes are proteins. Therefore, how would you explain carrying a gene for a trait that does not show up in the offspring?

– In order for DNA to pass genetic information to the next generation, DNA must replicate successfully. Mistakes in replication could result in major problems in heredity.

– Explain how DNA replicates.

– Describe the formation of the leading strand and lagging strand and include the enzymes involved.

Why do the legs replicate differently?​
