Answer:
Non-coding DNA regions play important roles in regulating transcriptional activity by encoding different types of non-coding RNAs (ncRNAs), acting as scaffold attachment regions, acting as enhancer specific regions, etc.
Explanation:
Historically, it had been believed that non-coding DNA sequences were 'junk DNA' since they don't encode for proteins (beyond the sequences that are transcribed into functional non-coding RNAs, i.e., transfer RNA and ribosomal RNA). However, in the last years, it has been shown that non-coding DNA sequences play critical roles in regulating gene expression and genome function. For example, evolutionary conserved non-coding RNAs (ncRNAs) with regulatory roles on gene expression such as, for example, long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) have been mapped in non-coding DNA sequences, thereby evidencing the functional significance of these regions. In consequence, the conservative nature of certain non-coding DNA sequences evidence that mutations in such regions may have significant deleterious effects, and thereby they could have a negative impact on the fitness of the individual.
Answer:
The answer to your question is ACUCTTCUGGUCCCAACA
Explanation:
Base sequence
TGAGAAGACCAGGGTTGT
Nitrogenous bases change from DNA to RNA
DNA RNA
Adenine Uracil
Thymine Adenine
Guanine Cytosine
Cytosine Guanine
Then from left to right, the new sequence the RNA is
ACUCTTCUGGUCCCAACA
Interphase:
Is known as the resting stage. Replication of DNA occurs.
- G1
-S
-G2
Prophase:
The chromosomes are visible, centrioles are formed and begin to move to opposite sides. This is where you see the dissolving of the nuclear membrane.
Metaphase:
The chromosomes line up in the centre of the cell.
Anaphase:
This when the cell divides (should look like two circles splitting) you will see the spindles begin to shorten which pull chromatids apart.
Telophase:
The nuclear membrane is reformed.
