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:
sun
Explanation:
there would be no life whatsoever if we have the sun.
Answer:
For the object of to be considered alive , it must have DNA and all the characteristics of living things.
Explanation:
If one is to determine whether the object is alive or not the object should possess all the properties of living things. firstly, it should have the genetic material the DNA without which the cell can't be alive or the nucleus in case of PROKARYOTES. it should have the ability to reproduce, move , to grow and to excrete without which it would not be considered alive.
