<h2>CRISPR/Cas9</h2>
Explanation:
CRISPR can be used to reintroduce dystrophin back into the KO mouse
- CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats and is used to for gene editing
- CRISPR/Cas-mediated genome editing has been shown to permanently correct DMD mutations and restore dystrophin function in mouse models
- Germline editing by injecting zygotes with CRISPR/Cas9 editing component was first done in mdx mice by correcting the mutated exon 23
- Postnatal editing of mdx mice was then achieved using recombinant adeno-associated virus to deliver CRISPR/Cas9 genome editing components and correct the dystrophin gene by skipping or deleting the mutated exon 23 in vivo
- Germline and postnatal CRISPR/Cas9 editing approaches both successfully restored dystrophin function in the mice and same technique can be used for KO mouse model
This is because it is a monocot and monocots do not have a vascular cambium in their stems.
Answer:
A. The heartbeat can be heard
Explanation:
After the first trimester, during the fourth month, the heartbeat of the fetus becomes loud enough to be heard with the help of a stethoscope placed on the abdomen of the mother.
From fifth to the seventh month of the development, kicks and jabs are felt by the mother as the fetal legs grow and develops. Languo, a wrinkled pink colored skin covers the fetus.
Languo is in turn covered with a white greasy substance called vernix caseosa.
From eighth to ninth months, rotation of the fetus places its head pointing towards the cervix to facilitate childbirth later.
The development of testes takes place in the seventh month while the body hairs become disappeared in the eighth month.
Answer:
the dogs secure there offspring by getting them food
Explanation:
Answer:
A. Catabolic
B.Anabolic.
C. Anabolic
D. Catabolic.
E.Anabolic
F. Catabolic
G. Anabolic
H. Catabolic
Explanation:
Catabolic process is a metabolic processes that breakdown complex or larger molecules into smaller sizes by releasing energy.
The examples of such metabolic processes are;
Glucose is used as the primary fuel for energy
Dietary carbohydrate from a meal is digested and absorbed as monosaccharides, mainly glucose
Dietary protein from a meal is digested and absorbed as single amino acids.
Fatty acids are used as fuel sources for some tissues.
All this processes are catabolic processes because large molecules are broken to smaller ones and all this processes release energy.
Anabolic process is a metabolic process where smaller molecular are build up to form larger molecules and this requires the input of energy.
Examples are;
Glucose is used as the primary fuel for energy
Excess glucose is stored as glycogen in the liver and muscle.
Excess glucose is converted to fatty acids and stored as part of the triglyceride molecule in adipose tissue
Excess tatty acids combine with glycerol to form which are stored in adipose tissues.
All these processes requires the build up of smaller molecules to larger molecules and requires input of energy.
