Ribose sugar is only found in RNA, DNA has Deoxyribose. The D in DNA stands for Deoxyribose.
The answer is C.
A virus is made up of or consists of a nucleic acid in varying quantity which may either be RNA or DNA.
The nucleic acid is surrounded by a protein shell called a capsid. The word capsid comes from the Latin word capsa which means box.The capsid and the nucleic acid within it are together referred to as nucleoprotein.The capsid is made up of small sub units called capsomeres.
In many viruses, the nucleoprotein makes up the whole virus. More complex viruses have one or more further enclosing structures also made mostly of protein. These structures are referred to as envelopes and each envelop is specific to a particular virus.
The kind of cross that the figure describes is a dihybrid cross.
There are different types of cross. In this case, we have a dihybrid one.
<h3>What is a dihybrid cross?</h3>
A dihybrid cross happens between two individuals, animals, or plants with two different pairs of genes.
In this case, the two sets of genes that crossed are:
<h3>Parent 1 gene pairs</h3>
- The h0m0zygous dominant RR
- The h0m0zygous dominant YY
The result is RY.
<h3 /><h3>Parent 2 gene pairs</h3>The h0mzygous recessive rr
- The h0mzygous recessive yy
The result is ry.
As a result, the cross is a dihybrid one because RY and ry, which are two heterozygous pairs that code for different traits, crossed.
RY x ry
