g statements regarding restriction enzymes is NOT true? See Section 15.1 (Page 554) . Most restriction enzymes recognize sequences of 20-25 bp in length. Bacteria can add methyl groups to their DNA to prevent digestion by endogenous restriction enzymes. Most restriction enzymes recognize palindromic sequences in host DNA. Restriction enzymes may produce either sticky or blunt ends when digesting host DNA.

Answer:

Most restriction enzymes recognize sequences of 20-25 bp in length

Explanation:

Sequences of DNA that are recognized by restriction enzymes are called recognition (or restriction) sites are usually are between 4 and 8 bases long. Many of them are palindromic, which means that they are the same when you read it backwards and forwards (mirror-like).

Restriction enzymes are endonucleases, which means they cut phosphodiiester bonds within DNA. These enzymes are from prokaryotic organisms (archea and bacteria) which use them as defending mechanism against viruses. Prokaryotes protect their own DNA via methylation, performed by methyltransferase.

Answer:

Just before the cat drops, it was stationery. Therefore it has energy of position called  potential energy.As it drops, the Gravitational potential energy is converted to Kinetic Energy,The conversion mid- air is P.E to K.E to P.E to K.E to P.E to K.E, until it touches the ground. As it touches the  ground all the energy is converted to P.E energy of position.

As it runs after mouse the P.E is converted back to Kinetic , energy of motion. As it feeds on the mouse , the chemical energy obtained  as protein from mouse meat.This is later converted back to Mechanical energy as (kinetic and Potential  energy)   in the cat.

During the absorptive state, metabolism adjusts to either provide energy for immediate use or store excess energy to be used lat
Effectus [21]

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.
