Answer:Mutations are rarely harmful though. Indeed, most mutations go unnoticed, as the body has mechanisms to stop a cell copying itself when a mutation occurs. Sometimes mutations can even benefit organisms and promote diversity in a species.

Answer: Harmful mutations may cause genetic disorders or cancer. A genetic disorder is a disease caused by a mutation in one or a few genes. A human example is cystic fibrosis. A mutation in a single gene causes the body to produce thick, sticky mucus that clogs the lungs and blocks ducts in digestive organs

All of the following are differences in transcription, RNA processing, and translation between prokaryotes and eukaryotes except

Mazyrski [523]

Answer:

the mRNA goes through extensive modifications such as addition of a poly tail and a 5' cap in eukaryotes but not in prokaryotes.

Differences:

- the promoters in prokaryotes have a -35 and -10 box while in eukaryotes they are variable but have a TATA box from

- the transcription initiation site there is a single RNA polymerase in prokaryotes while eukaryotes have multiple RNA polymerases

- the sigma factor associates with the promoter region in prokaryotes but in eukaryotes there are many basal transcription factors

Explanation:

Ribosomal and transfer RNAs are processed both in prokaryotic and eukaryotic organisms. However, mRNA is only processed in eukaryotes. In eukaryotic cells, mRNA processing involves:

1. Capping at the 5' end. This process has several functions including regulation of nuclear export, prevention of eukaryotic mRNA degradation and promotion of translation.

2. Splicing in order to remove introns and conserve coding exons. Splicing helps to increase the diversity of the eukaryotic mRNAs (and therefore eukaryotic proteins)

3. Polyadenylation by the addition of a poly(A) tail at the 3' end. The poly(A) tail makes the eukaryotic mRNA molecule more stable and also prevents its degradation by exonucleases.

Introducing additional organisms of the same existing kinds will not upset the ecosystem.

Drupady [299]

false, because if you add additional organisms, the food web would become lopsided, causing the organisms food to decrease.
