Every enzyme has a different what?

Montano1993 [528]

Answer:

Every enzyme has a different catalytic activity.

Explanation:

This means it can be used to do something that other enzymes can't, such as differentiating between sugars in order to change the sugar content of food.

Another advantage? The wide range of uses for these enzymes when food preparation is approached creatively and with an open mind: With so many diverse tastes and textures to be found among edibles, an ample supply of suitable enzymes could enhance any dish!

(protein)?

belka [17]

Answer:

Since, the original DNA sequence has not been provided, the mutation can be an insertion/deletion or a frameshift mutation.

Mutated DNA
Frameshift mutation/ insertion or deletion
All the amino acids changed after the point mutation

Explanation:

Frameshift Mutation:

A frameshift mutation is the alteration in the reading frame of the DNA due to the addition/deletion of one or two nucleotides.
This type of mutation moves the mRNA sequence one or two bases forwards or backwards which disrupts the three base codons sequence required for translation into proteins.
The CT at the end of the sequence is indicative of a frameshift in the DNA reading frame.
Frameshift mutation affect all amino acids in a polypeptide chain as all codons are moved one or two steps forwards or backwards.

A neuromuscular junction is a junction between a_________ and a ___________. A neuromuscular junction is a junction between a___

garri49 [273]

Answer:

myofibril bulbous end of axon and skeletal muscles fibres.

Explanation:o

It represents the chemical synapse of the axon bulbous ends of the motor neuron ( motor end plate) and the skeletal Muscle fibres.

The influx of calcium ions into the bulbous ends leads to the fusion and empty of the vesicles containing neurotransmitters into the synaptic cleft.

The Neurotransmitters binds to the receptors on the muscles membrane to allow the transmission of action potential ( PSIP or PSEP)across the synaptic gap to the muscles fibers to initiate their contraction or relaxation.

Given the following cross TtYyRr x TtyyRr (T = tall; t = short Y = yellow; y = green R = round; r = wrinkled), what proportion o

mihalych1998 [28]

Answer:

3/32 ttyyR-

Explanation:

Cross: Tall, Yellow, Rounded individuals with a tall, green, rounded individual

Parentals) TtYyRr x TtyyRr

Gametes) TYR, TyR, TYr, Tyr, tYR, tyR, tYr, tyr (Parent one)

TyR, TyR, Tyr, Tyr, tyR, tyR, tyr, tyr (Parent two)

We need to know what proportion of offspring is expected to be short plants with round, green seeds. So we need to identify the gametes for these traits. The genotypes are:

Shot → tt
Round → RR or Rr
Green → yy

⇒ Parent one can provide gametes tyR and tyr

⇒ Parent two can provide gametes tyR and tyr

(1/8 tyR x 2/8 tyR) + (1/8 tyR x 2/8 tyr) + (1/8 tyr x 2/8 tyR) =

2/64 ttyyRR + 2/64 ttyyRr + 2/64 ttyyRr =

1/32 ttyyRR + 2/32 ttyyRr =

3/32 ttyyR-
