gizmo_the_mogwai [7]

Answer:

T A A G T C G C T

Explanation:

DNA strand:                             A T T C A G C G A

complementary DNA strand:  T A A G T C G C T

This is a very important rule:

Four kinds of nitrogenous bases in DNA: Adnine (A), Thymine (T), Guanine (G), Cytosine (C)

And this is how they're coupled:

A = T

C = G

For example::

First DNA strand:                  A T G C

complementary strand:        T A C G

Which of the following is NOT a feature of cardiac muscle fibers?
Andreyy89

Answer:

(1)They are usually multi-nucleated.

Explanation:

Cardiac muscles are one of the three muscles found in the human body (the other two being skeletal and smooth muscles). It is the only type of muscle found in the heart. Cardiac muscle cells have a single nucleus unlike the skeletal muscle cells.

They possess many large mitochondria in their cell, which enable them actively carry out the process of aerobic respiration. The cardiac muscles contains an enormous amount of myoglobin pigment, which enable them store and transport oxygen. Due to the high glucose in its cell, excess glucose is readily stored as Glycogen, making it rich in glucose.

Based on the explanation, being MULTI-NUCLEATED is not a feature of cardiac muscle fibers.
