Describe the relationship between DNA, chromosomes, and genes.

2 answers:

7 0

Answer: DNA ( deoxyribonucleic acid) is a chemical substance which is called as the genetic material of all living organisms. It is packaged into the threadlike structure, called as chromosomes. This means that chromosomes are composed of a chemical substance, which is called as DNA.

Whereas, genes are the segment of DNA ( which code for specific proteins) present on the chromosomes. Thus, they carry information for specific trait of the individual ( like eye color)

In summary, their composition and functions are similar as all play a significant role in passing information from one generation to next and thus, determine the characteristics of the offspring.

DNA (Deoxyribonucleic acid) is the double stranded molecule which carries the genetic information. The long stretch of DNA is condensed to form a compact structure called as chromosome. A gene is sequence of DNA which encodes a protein.

Further Explanation:

DNA is enclosed in the nucleus of eukaryotic cells but in prokaryotes DNA is present in the cytoplasm. DNA is transcribed to RNA and then it is translated to form protein.

Different genes encodes for different types of protein. A chromosome is the condensed form of DNA where it is wrapped around the histone protein which resembles the beads on a string. And this structure is called as nucleosome and it prevents the accessibility of the DNA from transcription factors. Chromatin is the structure which contains group of nucleosome and the next highly condensed level is the chromatin loops.

Chromosome contains a group of genes and there are 23 pairs of chromosomes in the human somatic cell. Therefore, chromosome is a thread like and highly coiled structure which compacts DNA inside the nucleus.

What do acids do do ph

Sergio [31]

Answer:

An acid increases the hydrogen ion concentration in a solution, while a base decreases the hydrogen ion concentration. pH is used to measure the concentration of H+ ions ([H+]) and therefore, whether a substance is acidic or basic (alkaline).

Identify the location where the sex cells of each reproductive system mature.

Y_Kistochka [10]

The correct answer is D -ovary for the left (female reproductive system) and Q-epididymis for right (male reproductive system).

Ovaries are the primary female sex organs that produce the female gamete (ovum) and several steroid hormones (ovarian hormones). The ovaries are located one on each side of the lower abdomen. Each ovary is about 2 to 4 cm in length and is connected to the pelvic wall and uterus by ligaments. The formation of a mature female gamete is called oogenesis. Oogenesis takes place in ovary and is initiated during the embryonic development stage when a couple of million gamete mother cells (oogonia) are formed within each fetal ovary.

Testis are the primary sex organ in males. Spermatogenesis is process by which sperm is produced in testis. Spermatogenesis starts at the age of puberty due significant increase in the secretion of gonadotropin releasing hormone (GnRH). This, if you recall, is a hypothalamic hormone. Sperms released from the seminiferous tubules, are transported by the accessory ducts. Secretions of epididymis, vas deferens, seminal vesicle and prostate are essential for maturation and motility of sperms. The seminal plasma along with the sperm constitutes the semen.

inessss [21]

Translation is a step of the DNA sequence which matches each nitrogen base to its counterpart. In this case, the counterpart of A is U, T is A, G is C and C is G. Given the sequence AAGCTGGGA , the sequence after translation would be UUCGACCCU. Answer is B
