HELP me!!! DNA!?

Question

How does DNA found in the nucleus of cells control the expression of physical traits such as the shape of pea seeds

Answer 1

DNA encodes proteins, (depending on your knowledge of DNA) it is made up of nucleotides consisting of nitrogenous bases, a double helix is how the bases and other molecules are held together as DNA, the combination of bases codes for different amino acids so every triplet of bases codes for 1 amino acid, in processes of transcription and translation, the DNA sequence is converted to mRNA and the codons on the mRNA (3 bases in a row) match with the anticodons on tRNA, tRNA molecules carry a specific amino acid depending on what bases the tRNA molecule is made up of. so as more codons match with anticodons, more amino acids are brought together, it is the combination of these which determines the physical traits (phenotype) of the organism

Answer 2

The DNA, or more specifically, the genes located on chomosomes determine the traits. This occurs through genetic inheritance of dominant/recessive genes.

Physical traits arise either from one gene dominating another, by two codominant genes being expressed at once, or by there being only recessive genes. (in which case, the recessive trait is expressed)

Basically, DNA is the source of the genetic information that creates genes, which determine the phenotype (physical trait).

Answer 3

DNA is the substance that holds the genes that determine the characteristics of the pea seeds

Answer 4

DNA is made up of several genes. The genes code for proteins, and different proteins have different functions (controlling shapes, colors, size, etc.)

Answer 5

Can't help you, darlin' I'm in Kentucky....all the DNA is the same here.
