. What is thought to be the purpose of the non-coding regions of DNA?
How do mutations affect the phenotype? take into considerations coding and non-coding regions.
3) With reference to nucleic acids (DNA/RNA), answer the following questions: 1) what are the coding and non-coding regions of pre-mRNA (non-functional mRNA) called (1/2 point each); ii) name the enzyme that splices out non-coding regions of pre- mRNA (1/2 point), iii) name the enzyme that joins coding regions to generate mature- mRNA (functional mRNA) (1/2 point); iv) name the major enzyme (1/2 point) involved in the "Polymerase Chain Reaction" and what is the major application of PCR (1/2 point);...
What do we know about non-coding DNA sequences?
What is non-coding DNA, and why is it necessary? Describe some of its roles
The non-coding spacer regions (barcodes) differ from species to species due to insertions and deletions in the DNA sequence. We expect our products from the three primers sets will be approximately 600 bp long (+/- 100 bp). Given that our polymerase extends at 1 kb/minute, how long should we set our extension time for?
3. The genome of living organisms includes coding and non-coding regions, plus the genetic material of mitochondria and chloroplasts (when present). Describe the mechanism by which genes express their function. (b) Consider an instance in which two alleles of a gene differ by one single nucleotide. How could these two alleles lead to substantially different functional outputs?
14. Which part of human DNA has the most variable nucleotide sequence? The non-coding DNA between genes. B.) The coding part of the genes. The regulatory part of the genes. D. The dominant alleles. E. The recessive alleles.
(Molecular Biology) What specifically is coding DNA? Only roughly 2% of the human genome is made up of coding gene sequence. Briefly describe 4 types of the non-coding other 98% of DNA
Telomeres are long stretches of non-coding DNA at the ends of linear (eukaryotic chromosomes. A beneficial effect of having telomeres is that they -7 speed up the rate of cell proliferation. B)prevent shortening of the leading strand of the DNA during replication prevent shortening of the lagging strand of the DNA during replication D. eliminate the need for RNA primers during DNA replication E. help to splice out introns
1. Using the following terms, describe the process of transcription a. Template strand, non-template/coding strand, DNA, RNA, RNA polymerase, 3 5, 5 3', uracil, promoter, termination sequence, enhancer, nucleus, cytoplasm. What process often follows transcription? How is the genetic code used in this process ?
