The C. elegans genome is about 100,000kb. If C elegans genomic DNA is digested with XbaI, which recognizes and cleaves the seque

Answer:

25000 fragments

Explanation:

A restriction enzyme can cut a random DNA sequence once per every 4^n where n = number of bases in the recognition site of enzyme.

There are 6 bases in Xbal's recognition site (TCTAGA) so it will cut once per every 4^6 = 4096 bases (4kb).

Total genomic size = 100000kb

So expected number of fragments = Total genomic size/Size of one fragment

= 100000/4

= 25000 fragments

DerKrebs [107]

Answer:

a network of proteins that holds homologues together.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

The synaptonemal complex is a network of proteins that holds homologues (homologous chromosomes) together.

Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.

Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;

I. SC protein-1 (SYCP1).

II. SC protein-2 (SYCP2).

III. SC protein-3 (SYCP3).

In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.

This is the process of changing energy from one form to another. Solar energy is changed into chemical energy by plants.
Colt1911 [192]

Answer:

Energy Transformation

Explanation:

The conversion of energy from one from to another is known as energy transformation.

Energy can only be converted or transferred from one object to another or to a different location but it can never be created from scratch. A good example is given in the question that solar energy is converted into chemical energy with the help of plants.

I hope the answer is helpful.

Thanks for asking.

son4ous [18]

The answer is (A. A warm current flows along the coast.) Currents carry cold and warm water from place to place. It's an amazing phenomenon that scientists are still trying to fully figure out.  Some think it's caused by wind, others think it's caused by the shifting of the tectonic plates, but one thing's for sure, currents are VITAL for this planets life.
