Answer:
Element is a substance that cannot be broken down into simpler substances. Atoms are the smallest particle of an element. An element has a fixed composition because it contains only one type of atom.
Answer:
DNA ⇄ RNA → PROTEINS.
Explanation:
Central dogma explains the flow of genetic information of the living organism. The DNA is converted to RNA by transcription and further into protein product by the process of translation. DNA can increase its number by replication process.
Retroviruses do not follow the central dogma and they have the ability to convert the RNA into the DNA molecule by the enzyme reverse transcriptase. Their central dogma is as follows:
DNA ⇄ RNA → PROTEINS.
Thus, the answer is DNA ⇄ RNA → PROTEINS.
Group 13-17 contains metalloids. Boron, Silicon germanium, Arsenic, Antimony, Tellurium and Polonium are considered metalloids. They have properties of both metal and non metal. Some of the element are good semi-conductors .
Answer:
For a gene that is expressed in a dominant and recessive pattern, homozygous dominant and heterozygous organisms will look identical (that is, they will have different genotypes but the same phenotype), and the recessive allele will only be observed in homozygous recessive individuals.
Explanation
Answer:
An inversion
Explanation:
An inversion occurs when a chromosome breaks in two places; the resulting piece of DNA is reversed and re-inserted into the chromosome. Genetic material may or may not be lost as a result of the chromosome breaks.
