Three of the most common types of mutations are:

1. POINT MUTATION (one base is substituted for another)

If a point mutation changes the amino acid, it’s called a MISSENSE mutation.

If a point mutation does not change the amino acid, it’s called a SILENT mutation.

If a point mutation changes the amino acid to a “stop,” it’s called a NONSENSE mutation.

2. INSERTION (an extra base, or bases, is inserted)

3. DELETION (a base, or bases, is lost)

Deletion and insertion may cause what’s called a FRAMESHIFT, meaning the reading frame changes.

These are typically one of the most serious types of mutations.

Directions:

1. Following the same procedure you followed during the decoding activity (DNA to mRNA to

Amino Acid), decode the original and mutated sequences and identify them as one of the three

types of mutations listed above. If it is a point mutations, include whether it is a missense, silent,

or nonsense mutations.

The original DNA sequence is:

DNA: TGC GTG CTT AAG CGG TGT ACA CGT TGC

mRNA: ACG CAC GAA UUC GCC ACA UGU GCA ACG

Amino acid: Thr His Glu Phe Ala Thr Cys Ala Thr

Symbol: The fat cat

Answer from: Quest

Mantle convection is the slow creepingmotion of earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.[1][2] the earth's surface lithosphere, which rides atop the asthenosphere (the two components of the upper mantle), is divided into a number of plates that are continuously being created and consumed at their opposite plate boundaries. accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. this hot added material cools down by conduction and convection of heat. at the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of subduction usually at an ocean trench.[3]this subducted material sinks through the earth's interior. some subducted material appears to reach the lower mantle,[4] while in other regions, this material is impeded from sinking further, possibly due to a phase transition from spinel to silicate perovskiteand magnesiowustite, an endothermic reaction.[5]the subducted oceanic crust triggers volcanism, although the basic mechanisms are varied. volcanism may occur due to processes that add buoyancy to partially melted mantle causing an upward flow due to a decrease in density of the partial melt.secondary forms of convection that may result in surface volcanism are postulated to occur as a consequence of intraplate extension[6] and mantle plumes.[7]it is because the mantle can convect that the tectonic plates are able to move around the earth's surface.[8]mantle convection seems to have been much more active during the hadean period, resulting in gravitational sorting of heavier molten iron, and nickel elements and sulphides in the core, and lighter silicate minerals in the mantle.

Answer from: Quest

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.

What is the best conclusion based on this data? the hypothesis was not supported because the data indicated that fertilizing plants does not improve plant growth. the hypothesis was supported; to get the best growth, use 5 milliliters of fertilizer per plant. the hypothesis was not supported; the data indicated that too much fertilizer can inhibit plant growth. the hypothesis was supported; to get the best growth, use 15 milliliters of fertilizer per plant.
