Describe how and where viruses reproduce and the function of RNA and DNA in this process.
topjm [15]

Answer:

Using the host's cellular metabolism, the viral DNA begins to replicate and form proteins. Then fully formed viruses assemble. These viruses break, or lyse, the cell and spread to other cells to continue the cycle. Like the lytic cycle, in the lysogenic cycle the virus attaches to the host cell and injects its DNA.

There are two different alleles for flower color, P and p. The image shows a white sweet pea that is labeled with its two allele
Triss [41]

B. White petal colour is a recessive trait.

Explanation:

In Mendelian genetics, the alleles depicted in small letters are recessive traits.

Since both alleles are same and in lower case they are homozygous recessive alleles for a white coloured petal gene.

The genotype of the trait will be tt because if it is crossed either with heterozygous or homozygous P alleles it will appear as tt to have phenotypic trait of white colour.

So the genotype will be tt.

I need help ! i really don’t get it
Vaselesa [24]

Answer:

The presence of an additional chromosome

Explanation:

Look at "pair" 21. See how there are THREE chromosomes instead of TWO? Normally, there would only be two chromosomes in each pair but this karyotype shows a trisomy (see def. below) of the 21st pair. This was caused by a nondisjunction mutation of the 21st pair. The is also the karyotype of a person with Down's Syndrome.

Definition of Trisomy:

A condition of the presence of three chromosomes in a pair instead of two. This normally causes developmental irregularity.
