Howard is explaining the process by which DNA determines the structure of proteins. His explanation includes this statement. "Th
andrew-mc [135]

Answer:

Transcription and RNA processing (splicing)

Explanation:

Although Howard is almost right, the DNA sequence does not precisely relate to the protein sequence. First of all, the DNA is transcribed to an primary mRNA molecule. Bur before the mRNA is ready to be translated into an amino acid sequence, it must be processed into a mature mRNA.

This includes adding a 3' poly A tail, and a 5' cap, and importantly for this question, splicing.

Splicing is the removal of non protein coding intermediate sequences called introns from the protein coding regions (exons) of a primary mRNA. This means that lots of the DNA sequence is not dictated by the final protein, as many of the intervening sequences have been removed by splicing.

How do biotic and abiotic factors. Contribute to the health of an ecosystem ??? Please explain
sweet-ann [11.9K]

Answer: They do affect the health of an ecosystem.

Explanation: In an ecosystem there are many things that are biotic and abiotic. For an example: water is abiotic and plants/animals are all biotic, the water is not living but it keeps the ecosystem alive by quenching the thirst of the plants growing from the ground and the animals roaming around on the land. Dead animals and plants are not abiotic and they are now providing food for fungi and bacteria. Without the abiotic factors, it would be difficult for the biotic to survive.
