Answer:
Option B, the graph with high levels of RNA-amino acid and a low amount of RNA-DNA.
Explanation:
RNA is understood to be the first genetic material in cells because:
RNA is capable of both storing genetic information and catalyzing chemical reactions.
Essential life processes like metabolism, translation, splicing, etc. evolved around RNA.
It has the tendency of self-replication.
Therefore, RNA-amino acid hydrogen bonds were more readily abundant than RNA-DNA bonds.
Answer: A segment of dna/chromosome containing the instructions for building a protein which will result in a trait is called a GENE.
Explanation:
CHROMOSOMES are made up of two threads called chromatids joined at a point called the centromere.
In the chemical nature of chromosomes, each is made up of a protein framework which has a long molecule of DNA (deoxyribonucleic acid) coiled round it. A segment of DNA containing the instructions for building a protein which will result in a trait is called a GENE.
The GENES in the cell of a diploid organism contain all the necessary instructions for building up the organism.These instructions are written on a molecular scale.. Most genes contain information to direct the synthesis of specific proteins. Each such protein takes part in the development of a particular character.
A protein is made up of one or more chains of amino acids known as polypeptides. The sequence of bases in a DNA molecule determines the type of amino acid and the sequence in which they are arranged in a polypeptide chain.
A gene therefore is a sequence of triplets of the four bases which specifies the structure of a protein
Answer:
Through denitrification. Nitrates are converted back to N2 gas by denitrifying bacteria. N2 gas is also returned to the atmosphere through volcanos.Explanation:simple science
Answer:
True.
Explanation:
Because genetic mutations effect not only humans but animals too. Its how things evolve, like humans. So yes.
