Answer:

A. chromosome

Explanation:

Chromosomes are typically what you see in a chart like karyotype that shows all the chromosomes of a particular organism. These are the highly condensed structures of DNA during replication which makes it easy to transfer DNA during replication.

Answer:

A. Chromosome

Explanation:

Each of your 46 cells has a chromosome, which is a very long strand of DNA with a combined length of around 3 meters! The DNA is wound around protein beads known as histones, and then histones are wound together to form larger and larger organized coils. This is done to prevent them from bunching and knotting together as headphones in your pocket used to before we were all wireless. The volumes of this blueprint, if DNA is the blueprint for everything that goes into creating our bodies, are known as chromosomes. Each of them has an extremely long word that can only be formed using four different types of letters (G, A, T and C). Genetic code is the process by which our body decodes a word to determine its meaning in smaller bits and the location of its genes. Genetic sequence is the term used to describe the letter order. The short arm, centromere, and long arm are the three structural components of each chromosome, which can vary in length. When a cell divides, it makes a copy of the chromosome, and the old and new copies are momentarily clipped to one another by their centromeres. The centromere is a particular segment of DNA that plays a crucial function in this process. Additionally, the centromere contains a "reel" connected to it that pulls the chromosome to each of the separated cells during cell division. Because the size of the chromosome arms is never exactly equal, one must be shorter and the other must be longer. Our genes are located in these arms.

The DNA that makes up the blueprints for all of the proteins your body produces is found in the core of each and every one of your cells.

The DNA organizes itself into 46 distinct bundles when a cell is prepared to divide. which, based just on size and the chains of nucleotides that make up the DNA's "ladder" portion, really seems to be 23 separate pairs of bundles (remember, 99.9 percent of all human DNA is identical from person to person, so the DNA you get from your mother looks an awful lot like DNA from your father). Unless you're a man, in which case you have two misaligned chromosomes and 22 pairs of chromosomes (that would be the "X" and the "Y").

Before a cell can divide it must copy one dna_____at a time in a process called DNA replication.
svetoff [14.1K]

Answer:

Before a cell can divide it must copy its DNA one

DNA replication is the process by which a molecule of DNA is duplicated. When a cell divides, it must first duplicate its genome so that each daughter cell winds up with a complete set of chromosomes.

Tomtit [17]

Answer:

I hope this will help

Explanation:

When you drink too much water, your kidneys can't get rid of the excess water. The sodium content of your blood becomes diluted. This is called hyponatremia and it can be life-threatening.

Hyponatremia is a low sodium concentration in the blood. It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. Symptoms can be absent, mild or severe. Mild symptoms include a decreased ability to think, headaches, nausea, and poor balance.

Trava [24]
I believe he is looking for an allele
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosomes. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.
