A plant that produces wrinkled, green seeds was mated to a plant that produces phenotypically round, yellow seeds. In the F1 gen
sergejj [24]

Answer:

Genotype of the parental plant that produced round, yellow seeds is RRgg

Explanation:

Let us say that allele for round shape (R) is dominant over allele for wrinkled shape(r)

and allele for green color (G) is dominant over allele for yellow color of seed.  

So a wrinkled green seed will have genotype either "rrGG" or "rrGg"

Like wise a round, yellow seeds will have genotype either "RRgg" or "Rrgg"

It is given that In the F1 generation, half of the plants produced round, yellow seeds and the other half produced round, green seeds.

So if a cross is carried between rrGg and RRgg, the following offspring will be produces

rG          rG         rg         rg

Rg RrGg RrGg Rrgg Rrgg

Rg RrGg RrGg Rrgg Rrgg

Rg RrGg RrGg Rrgg Rrgg

Rg RrGg RrGg Rrgg Rrgg

So genotype “RrGg” gives round and green seeds

And genotype “Rrgg” gives round and green seed

Thus, genotype of the parental plant that produced round, yellow seeds is RRgg

Which description is true for both DNA and RNA molecules
GrogVix [38]

The correct answer is A.

Both DNA and RNA are types of nucleic acids.  DNA stands for deoxyribonucleic acid , while RNA stands for ribonucleic acid.

Both DNA and RNA carry genetic information. However,  DNA is chiefly responsible for storing and transferring genetic information whereas RNA acts as a messenger between DNA and ribosomes during the process of protein synthesis and directly codes for amino acids.

DNA is double stranded while RNA is single stranded.

DNA has thymine in its structure but RNA does not. Instead in place of thymine it has uracil.
