When the genome of a particular species is said to include 20,000 protein-coding regions, what does this imply? a) there are 20,000 genes. b) each gene codes for one protein. c) any other regions are "junk" dna. d) there are also genes for rnas other than mrna. e) the species is highly evolved.

C

Explanation:

DNA especially I higher organisms contains coding and non-coding regions. Some of these non-coding DNA is transcribed into non-coding RNA such as regulatory RNA and t-RNA. These non-coding regions also form parts of centromeres and telomeres. It has been discovered that humans DNA has a lot of non-coding DNA.

answer; /// i believe the correct answer is (reactants);

the correct answer is: d. the saltine and pretzel are made of flour, yeast, and baking soda, and salt. the pecan contains no flour but it does contain fats. the pecan is a nut that can be consumed as a healthy snack. first of all, pecans are a source of fat (monounsaturated fat), but they provide less fat than some other nuts. pecans are a rich source of dietary fiber, manganese magnesium, phosphorus, thiamin, vitamin e…
