Answer:
The correct answer is - DNA --> RNA --> amino acid --> protein --> phenotype.
Explanation:
DNA encodes for the RNA and RNA encodes for the proteins in the process of central dogma to produce protein in two processes called transcription and translation to produce protein.
It begins with encoding DNA into RNA (mRNA), known as transcription, which is moved to the ribosome to translate into amino acid chains with help of tRNA and makes a specific protein which could be a form of genotype which express itself to produce a specific trait that makes a particular phenotype of that trait.
Answer:
Rr × Rr
Explanation:
Gregor Mendel, the father of Genetics, performed several experiments that led to the principles that govern heredity. He discovered that; an organism receives two forms of a gene called ALLELE, from each parent. According to his law of dominance, he also discovered that an allele is capable of masking another for a particular trait. He called the allele that masks or is expressed DOMINANT allele while the allele that is masked RECESSIVE allele. But in exception to this rule, genetic scenarios have occured.
For example, in cattles, where the allele for red hair (R) is not dominant or recessive to the allele for white hair (r), instead, they are both and equally expressed in the offspring. This genetic scenario is called CO-DOMINANCE.
In cattles, purebred red cattles (RR) i.e. homozygous or having identical alleles crossed with purebred white cattle (rr) i.e. also homozygous, will result in F1 Roan cattles (Rr), which is an hybrid or heterozygote i.e. combination of two different alleles. The roan cattle expresses both the phenotype of the parents i.e. possesses both red and white hairs.
To get the F2 offsprings/generation, the F1 offsprings are self crossed i.e. the hybrids are crossed together Rr × Rr.
It is the Foramen Ovale. The foramen ovale is a little gap situated in the septum between the two upper councils of the heart. The foramen ovale is utilized amid fetal dissemination to accelerate the go of blood through the heart.
The one fatal cardiac shunts, the other being the ductus arteriosus. Another comparative adjustment in the embryo is the ductus venous. In many people, the foramen ovale closes during childbirth.
Gregor Mendel was the "father of modern genetics" and helped disprove the blended theory of inheritance.
Answer:
a. do not immediately increase in number when placed in a culture
Explanation:
When bacteria placed in a new culture it shows a pattern of growth which is known as sigmoid growth. It has four phases lag, log, stationary, and death.
The lag phase occurs because bacteria do not start dividing immediately just after the placed in the new culture media because bacteria first adapt to the new environment and prepare enzymes needed for metabolizing the new substrate.
As the bacteria pass this lag phase it starts to divide at an exponential rate. Therefore it is true that most bacteria do not increase in number immediately after placed in a new culture.
