Answer:
Centromeric DNA
Explanation:
Genes are responsible for formation of proteins. A codon produces a single amino acid and it comprises of three base pairs. The whole DNA of organism does not contribute to encode protein. There are sequences in DNA that does not contribute in coding known as non-coding DNA and perform different functions. These may include the O O O 5-end, DNA coding for a signal sequence, noncoding intron and O promoter sequence .
The centromere is the part of DNA that links the sister chromatids. The centromere is not converted to mRNA or proteins. It is also not involved in regulation of genes. So it did not contribute to 864 bp found in the yfg gene.
Answer:
I'm not sure if your asking about a A, B, C, D question but, as far as I can tell this is what I know
Explanation:
(:Comparing:) Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms. ... Herbivores—organisms that eat plants—occupy the second level. Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level.
(:Contrasting:) Examples include plants, algae, and some types of bacteria. Heterotrophs are known as consumers because they consume producers or other consumers. ... Herbivores—organisms that eat plants—occupy the second level. Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level.
Hope this helps.
I think it's D. Sry if you get it wrong though
