DNA REPLICATION: This is a gene strand of DNA. Using the base pairing rules, write down the sequence of the template strand. Access easy-to-understand explanations and practical examples on key biology topics, from cells to ecosystems. Learn at your own pace with bite-sized, verified content.
During transcription, the sequence of nucleotides in the gene in DNA is copied into a corresponding sequence of __________________ in mRNA. protein in the blood; carries oxygen. During transcription, the enzyme, ________ ________________, separate the 2 strand of DNA & make the mRNA molecule by adding RNA nucleotides.
Within double-stranded DNA, the nitrogenous bases on one strand pair with complementary bases along the other strand; in particular, A always pairs with T, and C always pairs with G. Then,...
Explain why ORF scanning is a feasible way of identifying genes in a prokaryotic DNA sequence. 2. What modifications are introduced when ORF scanning is applied to a eukaryotic DNA sequence? 3. Describe how homology searching is used to locate genes in a DNA sequence and to assign possible functions to those genes. 4.
During gene expression, one continuous strand of genomic DNA is used as a template to produce a single-stranded RNA transcript. This process is called transcription. The sequence of this RNA transcript is identical to the nontemplate strand of genomic DNA (although RNA has a uracil in place of the thymine base).
8 lip 2009 · Genes are specific sequences of bases that encode instructions for how to make proteins. The DNA sequence is the particular side-by-side arrangement of bases along the DNA strand (e.g., ATTCCGGA). Each gene has a unique DNA sequence.
12 lis 2021 · When we look at a sequence of DNA, we read it in the 5′-3′ direction. The relative positions of genes or other sites along a DNA strand can be described as upstream (towards the 5′ end) or downstream (towards the 3′ end).
