If the genetic material is RNA, it will usually be single stranded. Only viruses contain double stranded RNA.
The main genetic material in eukaryotic cells (eg. animal cells) is DNA. Single stranded RNA copies of this (known as mRNA) are made in order for proteins to be synthesized.
Parthenogenesis. There are also a few species of animals that reproduce using the semen of similar species but the genetic material in the semen is not incorporated into the embryo. I don't remember the term for this type of reproduction but will ad it when I can.
Because if they didn't, predators would eat them to extinction.
Hybridisation is the crossing of two species. It is not common and the result is usually sterile. A good example of this is the mule, using a mare and a jack donkey. The mule has the courage, stamina and surefootedness of the donkey with the strength of a horse, and has been a very useful pack animal that played an important part in history. Some hybrids are unintentional, like a lion and a tiger breeding (result being a liger or a tigon, depending on which parent was the lion and which the tiger.) Hybridisation does occur naturally, but it is uncommon because animals prefer to breed with their own species.Hybridization is the process of combining two complementary single-stranded DNA or RNA molecules and allowing them to form a single double-stranded molecule through base pairing.
The roosters crest is called a Comb. Combs com in several shapes and each has a different name. Pea comb, single, double or rose.
I am assuming you mean the red things hanging under the "chin" of the hen. Yes, they are called wattles, the puffy red things on the top of the head are called combs. Both these features can be single or double.
Two types of nucleic acids DNA and RNA.These can be double stranded or single stranded.
Ebola has a single stranded set of RNA
List the features you think they are not.Viruses are classified mainly on their genetic material, such as DNA or RNA with its strand specificity single stranded or double stranded.
It is single stranded RNA. Importantly, it is also a segmented genome that allows it to have large genetic diversity.
A virus.Some viruses have double-stranded DNA, some have single-stranded. There are also viruses that carry their genetic information in RNA, some double-stranded, some single.
Infuenza Virus Contain Both DNA and RNA. No other Virus show such characteristics.
tRNA, or transfer RNA, is a single stranded molecule. The only double stranded RNA is dsRNA, or double stranded RNA. They are typically found in viruses.
In the protein capsid i.e. the part of the virus that is called the head. Note that only the genetic material i.e. double stranded DNA is injected into the host cell upon adsorption. Contrast this with influenza and HIV virus which introduce their genetic material ( i.e. single stranded RNA. HIV has two identical single stranded RNA, Influenza has eight different single stranded (-) RNA.) by receptor mediated endocytosis. Here. the protein capsid housing the RNA is introduced into the cell. A process called uncoating which refers to the breakdown of the protein capsid by enzymes exposes the RNA to the cytoplasm.
Ebola is a retrovirus so the genetic material is single-stranded RNA (ssRNA)
All viruses have genes made from either DNA or RNA but they themselves don't have DNA. (Viruses use tRNA or mRNA or DNA as a tool for infecting host cells, but they they do not use either for their own internal bio-mechanics)
no..it's double-stranded..
yes!Virus contains both DNA and RNAsome viruses contain RNA as their geneti information and are called retroviruses.when retroviruses infect a cell, they produce a DNA copy of their RNA.
