Answer:

The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.

Explanation:

Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into messenger RNA, called point gene mutations.

In the case presented, the substitution of the guanine base by cytosine in the GGA codon —resulting in a CGA codon— generates a change in the coding amino acid, resulting in arginine instead of glycine.

The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.

Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.

At which point does the motion of convention currents occur to drive plate movement

OLEGan [10]

Answer: 2

The convection currents shown in points 1 and 3 transfer heat from the outer core (number 4) to the lithosphere. Here, the lower density hot magma breaks apart the plates at point 2 creating a divergent plate boundary. This new magma mass will drive a lateral movement of the plates. The edges of the plates which have a higher density basalt rock will sink into the mantle and get consumed in trenches/subduction zones

Protein function may be terminated because its configuration was changed. this is called

larisa86 [58]

Protein Function may be terminated, disrupted, destruction of both the secondary and tertiary structure through the process called DENATURATION. Denaturation process does not break the primary structures since the link or sequence of peptide bond are greatly hold by Hydrogen bonding.

___________ is an autosomal recessive disorder that is more common in people of Jewish descent. It involves a lysosomal dysfunct

Elina [12.6K]

Answer:

Tay Sachs

Explanation:

Tay Sachs is a neurodegenerative disorder caused by the deficiency of enzyme hexosaminidase A in lysosome. Lysosome is responsible for degradation of lipid molecules which it carries out by the help of hexosaminidase A enzyme. In absence of the functional enzyme, lipids build up in lysosome which ultimately damages the cell and the tissue. Nerve cells are damaged the most in this disorder.

It is an autosomal recessive disorder which means that the mutant allele must be present in two copies for the production of symptoms. Symptoms are hypotonia, psychomotor regression etc. Its frequency is much higher in Jewish people of Ashkenazi descent. 1 in 30 Ashkenazi Jewish people has the mutant version of the gene.

The energy needed to "pump" sodium outside the cell in active transport is _____.

Bezzdna [24]

The correct answer is ATP

This stands for Adenosine Triphosphate which is the main source of all energy in the body. It is used in all types of active energy usage and is produced with processes such as the krebs cycle.
