Derived from the inner cells of a human blastocysts , a very early human embryo.
At the blastocyst stage, five to 10 days after fertilization,
the embryo is a cluster of 100-200 cells

Answer:

All embryonic stem cells are undifferentiated cells that are unlike any specific adult cell.

Human embryonic stem cells are derived from in vitro fertilized embryos less than a week old

Embryonic stem cells are of great interest to medicine and science because of their ability to develop into virtually any other cell made by the human body.

Scientists have been attempting to isolate and culture human embryonic stem cells for more than a decade.

Human embryonic stem cells will offer insights into developmental events that cannot be studied directly in humans in utero or fully understood through the use of animal models

In humans, the DMD gene is required for proper muscle function. Mutations in the DMD gene display X-linked recessive inheritance

ANEK [815]

Answer:

Explanation:

As the inheritance is X-linked,recesson so for expression of muscular dystrophy in any given muscle,

$\frac{enh1- enh2+ enh3 - DMD+ }{enh1- enh2+ enh3 + DMD+}$

enh1+ /enh1 + = Shows muscular dystrophy in heart (Homozygous for -)

enh2+/enh2+ = Shows no muscular dystrophy in arms (Homozygous for +)

enh3-/enh3+ = variabl or mosaic for muscular dystrophy in leg muscles (Hetrozygous for enh3)

Once amylase has broken down starch, can it break down another starch molecule?

Juliette [100K]

Answer:

Yes, amylase can be reused, and when fulfills its catalytic function, it is free to catalyze the breakdown of another starch molecule.

Explanation:

Amylase is an enzyme capable of catalyzing the breakdown of starch bonds, separating it into glucose molecules.

The enzymes, including amylase, have the property of being free and without structural alteration when catalyzing a reaction, to bind to the specific substrate and catalyze a new reaction.

Amylase is not consumed, unlike a reagent, so it can be reused in new reactions.
