What is the difference between DNA, chromosomes and genes? What is the difference between ministries and divisions in a federal system? Explain the difference between the mineralocorticoid and glucocorticoid actions of corticosteroids. What is the difference between cultural relativism and ...
What is the difference between autosomes and sex chromosomes? Does a 2n individual have homologous chromosomes or two copies of each chromosome? What is the difference between DNA, chromosomes and genes? How do diploid individuals have two copies of each pair of homologous chromosomes ?
Importance of DNA DNA is essential for all living things. The study of DNA has contributed to scientific discoveries and medicine. A DNA molecule can interpret anything from our parents’ qualities to the most likely behaviours of our future generations. DNA molecules and genes handle the unique ...
Select the best response: a risk difference of 0.56 per 1000 indicates an association between the exposure and the outcome. a. a positive, b. no, c. a negative. What is the difference between DNA, chromosomes and genes? Explain the need for cellular specialisation in a multi...
Chromosomes are found in the cell nucleus. They are condensed structures made of DNA and proteins. The genetic information they carry is expressed in the form of genes. These help in essential processes like DNA replication, cell division, and inheritance. If there are any changes made to the...
When it comes to genetic traits, scientists look at genes and the locus where that gene or trait encodes on the chromosome. Since humans possess two copies of each chromosome, they also have two copies of each gene and locus on those chromosomes. Each of these trait-encoding genes (or loci...
Haploid cells-The haploid number (n) is the number of chromosomes in a gamete. Gametes-- specialized sex cells formed in gonads by gametogenesis. The male gamete is the sperm, and the female is ovum(ova pl) or egg. Zygote- produced by fertilization between two haploid cells, the ovum and...
XY homologous genes Genes common to both sex chromosomes and therefore present in two copies in both females and males. Skewing of X chromosome inactivation When the process of X chromosome inactivation selects for or against alleles on the active X chromosome. This nonrandom pattern of inactivatio...
the characteristics of Turner's syndrome, with a complex and variable phenotype including short stature, gonadal dysgenesis and anatomical defects 1 . Both the embryonic lethality and Turner's syndrome are thought to be due to monosomy for a gene or genes common to the X and Y chromosomes 2 ...
Homozygous(and its less common formhomozygotic) means “relating to a cell that has two identical alleles for a particular gene at corresponding positions onhomologouschromosomes.” Let’s break that down. Chromosomes carry genes. A gene is a segment ofDNA—a string of code, really—that determ...
