Answer:
nucleotide, histone, nucleosome, tight helical fiber, supercoil, chromosome.
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
The complex structures of deoxyribonucleic acid (DNA) and protein found in the cell nucleus are generally referred to as chromosomes.
Chromosomes are found in the cell nucleus and are comprised of deoxyribonucleic acid (DNA), histone proteins, etc. Thus, they are used to store genetic informations in living organisms.
The human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.
In Genetics, the correct order of structures in a chromosome from smallest to largest are; nucleotide, histone, nucleosome, tight helical fiber, supercoil, chromosome.
Answer - C
Some DNA moves from one cell to the other, and each cell makes a complementary DNA strand with the genetic information from both the cells.
The digestive system plays an important role in the absorption of nutrients into the body. It takes the food we ingest, breaks it down mechanically and chemically in the mouth and stomach. It then absorbs nutrients, fats, proteins and water in the intestines before eliminating the waste through the rectum.
Answer: D: The tall gene in peas is dominant
Explanation:
When alleles are heterozygous, dominant genes will "overpower" the recessive gene.
The offspring in the pea plants had both alleles of the gene, but despite this, all of the pea plants were tall. This is because the dominant gene, the tall gene, was expressed over the recessive gene.
The correct answer is D.
B is also correct, but the question asks us to explain the tall gene, not the short one.
