How would a bacteria explore a non-coding portion of DNA?​

Answers

Explanation:

Non-coding DNA sequences are components of an organism's DNA that do not encode protein sequences. Some non-coding DNA is transcribed into functional non-coding RNA molecules (e.g. transfer RNA, ribosomal RNA, and regulatory RNAs). Other functions of non-coding DNA include the transcriptional and translational regulation of protein-coding sequences, scaffold attachment regions, origins of DNA replication, centromeres and telomeres. Its RNA counterpart is non-coding RNA.

The amount of non-coding DNA varies greatly among species. Often, only a small percentage of the genome is responsible for coding proteins, but an increasing percentage is being shown to have regulatory functions. When there is much non-coding DNA, a large proportion appears to have no biological function, as predicted in the 1960s. Since that time, this non-functional portion has controversially been called "junk DNA".[1]

The international Encyclopedia of DNA Elements (ENCODE) project uncovered, by direct biochemical approaches, that at least 80% of human genomic DNA has biochemical activity, which they defined as being transcribed, a definition not shared with most other biologists.[2] Though this was not necessarily unexpected due to previous decades of research discovering many functional non-coding regions,[3][4] some scientists criticized the conclusion for conflating biochemical activity with biological function.[5][6][7][8][9] Estimates for the biologically functional fraction of the human genome based on comparative genomics range between 8 and 15%.[10][11][12] However, others have argued against relying solely on estimates from comparative genomics due to its limited scope.[citation needed] Non-coding DNA has been found to be involved in epigenetic activity and complex networks of genetic interactions and is being explored in evolutionary developmental biology.[4][11][13][14]

Lactase is an enzyme that many different animals have that helps digest the sugar lactose Why can this enzyme be the same in different species?

0 Lactase is necessary for survival of all organisms

0 All living things share a common code-DNA

0 Lactase is not regulated by external environments.

It is not possible for it to be the same in different species

Answers

Answer:

All living things share a common code-DNA

Explanation:

Enzymes are proteinous substances, which like every other proteins are encoded by a genes. In the expression of these genes, a set of codons (three nucleotide base) called GENETIC CODE is used. ONE of the characteristics of this genetic code is that it is NEARLY UNIVERSAL meaning that the same genetic code is used by virtually all known living organism.

According to this question, lactase enzyme, which helps digest lactose sugar in organisms, is the same in different organisms. This is due to the fact that all living things share a common code-DNA e.g AUG codes for methionine in all organisms, hence, when these DNA undergoes expression, it yields the same products in different organisms.

What posture is a dog displaying if she is leaning away from your, body lowered, ears back, tail down, showing whites of her eyes and the corners of her mouth pulled back.

Answers

Answer: Fearful and worried posture

Explanation:

Since dogs cannot talk, their body languages are used to interpret whatever emotion or feeling they may be experiencing.

When a dog is afraid, she tries to look small. She lowers her body and and leans away so that her center of gravity is over her hind legs to  make a quick retreat easy. She also puts her tail down and ears flattened back to her skull. Her eyes also look rounder than normal and she shows the whites of her eyes (whale eyes).

All these tell that a dog is scared and worried or feeling tense.

Answer:

Defensive Threat Posture

Explanation:

Whale eye (whites of eyes showing)

Tail down or fully tucked

Piloerection

Ears back or flatten against head

Pupils dilated

Corners of mouth pulled back

Body lowered

Body leaning backward

A defensive threat posture indicates a dog is being self-protective. This is seen in a dog who is fearful and would prefer to run away from the situation, but may bite if provoked or cornered. Stress signals were offered in the beginning, however ignored and the dog is showing extreme fear.
