Protein coding repeats Samenvattingen, Notities en Examens

What is the difference between the coding and non-coding region? Coding region: comprised of genes that encode proteins (instructions that determine traits) and makes up 1-2% of human DNA. • Noncoding region: makes up 98-99% of human DNA, contains STRs and is responsible for regulatory functions such as gene transcription. What are STRs? Short-tandem repeats (STRs) are unique repeating patterns of the same nucleotide sequence. They can be used to differentiate one person from another....

1) A protein is 300 amino acids long. Which of the following could be the number of nucleotides in the section of DNA that codes for this protein? (Remember: DNA is double-stranded.) E) 1800 2) A short segment of an mRNA molecule is shown below. The polypeptide it codes for is also shown: 5′-AUGGUGCUGAAG : methionine-valine-leucine-lysine Assume that a mutation in the DNA occurs so that the fourth base (counting from the 5′ end) of the messenger RNA now reads A rather than G. What seq...

Nucleotide - ANS deoxyribose, a 5C sugar with a hydroxyl group on the 3' carbon and a phosphate group on the 5' carbon, and a nitrogen base attached to the 1' carbon Amino acid - ANS coded 5' to 3' (N terminus to C terminus) Central dogma - ANS describes the flow of information from DNA (genotype) to RNA (portable) to protein (phenotype) via transcription and translation Codon - ANS A specific sequence of three adjacent bases on a strand of DNA o...

Bio Practice Exam 28 Questions with Verified Answers Why did DNA evolve to be the carrier of genetic information in cells as opposed to RNA? - CORRECT ANSWER the hydrogen at the 2' position in the deoxyribose of DNA makes it more stable than RNA In the mismatch repair process, enzyme complexes replace bases that were incorrectly inserted into the newly synthesized DNA strand. To function, they must be able to distinguish between the parent DNA strand and the new strand. How is this accomp...
