Answer and Explanation:

UGA, UAG and UAA are the stop codons in the genetic code. During translation, these stop codons signal the end of the polypeptide chain. These codons do not code for an amino acid. Therefore they are called termination codons or nonsense codons. These stop codons have been called as ochre (UAA), amber (UAG) and umber or opal (UGA). Richard Epstein and Charles Steinberg revealed Amber (UAG). They named it amber while remaining two stop codons named as ochre (UAA) and opal (UAG) to maintain the theme of ‘colors names’. Stop codons release the new polypeptide chain from the ribosome, during protein synthesis. This happens because there are no tRNAs with anticodon corresponding to the stop codon.

Describe a DNA mutation and how it can affect an offspring.
Greeley [361]
A DNA mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes. DNA mutations can affect an offspring can result in abnormal protein products. Mutations can also introduce new alleles into a population of organisms and increase the population's genetic variation.

How would you describe the relationship that gravity has with mass and distance.
PSYCHO15rus [73]

Answer:

Mass does not affect gravity and distance has an indirect relationship.

Explanation:

The equation for gravity is, g = \frac{GM}{R^{2} }

where, G = gravitational constant

             M = mass of the planet

             R = distance between the bodies (object and center of planet)

so, gravity depends on the mass of planet,  not on mass of object

 and is inversely proportional to sqaure of distance.
