A mutation within a gene that will insert a premature stop codon in mrna would _______
AveGali [126]

A mutation within a gene that will insert a untimely cease codon in mRNA would result in a shortened polypeptide chain.

<h3>What occurs if there is a untimely end codon?</h3>

Thus, nonsense mutations occur when a premature nonsense or end codon is added in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins

<h3>What mutation motives untimely cease codon?</h3>

In genetics, a nonsense mutation is a factor mutation in a sequence of DNA that effects in a premature stop codon, or a nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and normally nonfunctional protein product.

Please help me?? I need help labeling the graph using the word bank
sladkih [1.3K]

Answer:

Explanation:

  1. Oceanic Plate
  2. Subduction Zone
  3. Convection Currents
  4. Asthenosphere
  5. Continental Plate

The Oceanic Plate is located near the ocean ridge. Which represents where magma creates new oceanic crust.

The Subduction Zone is where the tectonic plates meet.  These are called plate boundaries.  

Convection Currents are what drives the movement of rigid tectonic plates in Earth's molten mantle.

The Asthenosphere is the upper layer of the mantle. Which is below the lithosphere (Continental Plates).  

Continental Plates are the outer shell of the mantle.

Let me know if this helps!

What property of the DNA molecule explains the necessity for Okazaki fragments? DNA is antiparallel. DNA is a linear molecule. D
Arada [10]

Answer:DNA is antiparallel.

Explanation: DNA is a double stranded helix in which the two strands are antiparallel. Being antiparallel means that as one strand runs from 5'->3' direction, the other strand runs from 3'->5' direction. During DNA each of the two strands serves as a template for a new complementary strand. The synthesis of a new DNA strand is always in the 5'->3' direction, therefore one strand is synthesized continuously in the direction of the replication fork while the other strand is synthesized discontinuously in the direction opposite to the replication fork in short fragments called the Okazaki fragments. The strand that is synthesized continuously is called the leading strand while the strand that is synthesized discontinuously in Okazaki fragments is called the lagging strand.
