Answer:

Enzyme A

Explanation:

<em>Hello there?</em>

In the stomach, hydrochloric acid is present which is a strong acid (0-4) which is below pH 7. Therefore an enzyme that act best well here should be below pH 7 which for our case is A.

A number of different types of mutations in the HBB gene can cause human β-thalassemia, a disease characterized by various level
Lubov Fominskaja [6]

Answer:

Mutations in introns create alternative splicing site which in turn make mRNA with reduced or no translation.

Explanation:

Introns regulate the splicing of heterogenous RNA during post transcriptional modifications as well as affect the stability of mature mRNA. The stable mRNA is more likely to be translated into proteins. So, introns also regulate the translation of mRNA.  

In human beta thalassemia, mutations in intron create alternative splicing sites which in turn affect the formation of beta globin chain of hemoglobin. Lack of beta globin chain reduces the amount of functional hemoglobin and causes anemia.

What are some natural influences of the Tundra ?
grigory [225]
<span>Human influences in the Arctic are both seen and unseen.  Human activity has seen a dramatic change in the arctic due to climate change.  This is, by far the worse impact human activity has had on the globe, but in particular, the Arctic is fragile.  Other human influences are the vast and untapped oil reserves in the Arctic have made it a target for oil companies.  Oil and gas pipelines are a huge human influence in the Arctic.  Garbage and other waste not to mention the impact of the oil and gas industry have left some parts of the Arctic polluted.</span>

DNA can make exact copies of itself through replication because the nitrogen bases ALWAYS pair
Rainbow [258]

*What does replication mean?

Replication means to make an exact copy of itself. Like clones, or identical twins.

*Why would a cell need to replicate (make copies) of its DNA?

Our cells are always dividing and making new cells. Replication occurs before a cell divides so that each new cell will have the exact DNA as the original (parent) cells. Replication ALWAYS occurs in the nucleus of the cell.


Because of DNA's structure it can be copied or replicated. Each strand of the DNA double helix has all the information needed to reconstruct the other half by base pairing. Adenine will bond with thymine and guanine will bond with cytosine.


In Eukaryotes, DNA replication occurs at hundreds of places in both directions at the same time. It has been found to only take 3 minutes for a strand of DNA to be copied.


Replication is also very accurate. 1 error per 10,000 paired nucleotides. The cell has enzymes that proofread DNA and repairs errors as it builds the new strands of DNA during replication.


GOAL OF DNA REPLICATION:


Parent (original) DNA will separate at the hydrogen bonds where the nitrogen bases are attached into 2 single strands. Imagine taking a ladder and sawing it down the middle through all the steps.


Those half strands will make templates for the new strands to be made.


Now the original nitrogen bases no longer have their pair next to them.


New nitrogen bases will come in and fill the spots following base pairing rules (A-T, G-C)


2 (two) new strands of DNA will be created identical to the original.


Each of the new strands will have HALF of the ORIGINAL, and HALF brand NEW.
