What else can I help you with?
Are DNA and genes the same thing?
No, DNA and genes are not the same thing. DNA is the molecule that carries genetic information, while genes are specific segments of DNA that code for specific traits or characteristics.
Are genes and DNA the same thing?
No, genes are segments of DNA that contain instructions for making proteins, while DNA is the molecule that carries genetic information in all living organisms.
The hereditary information in DNA is encoded in the sequence of?
nucleotide bases adenine (A), thymine (T), guanine (G), and cytosine (C). These bases form complementary base pairs (A-T and G-C) and the sequence of these bases along the DNA molecule determines the genetic information.
What molecule contains the information on how to make proteins?
DNA contains the information on how to make proteins. This information is stored in the form of genes, which are sequences of nucleotides within the DNA molecule. Genes are transcribed into messenger RNA (mRNA), which is then translated into proteins by ribosomes.
Where are the genes held in a cell?
Genes in eukaryotic cells are in three places: the nucleus, mitochondria, and chloroplasts.A gene is a segment of DNA that codes for a polypeptide or for a molecule of RNA, such as a transfer RNA (tRNA) or ribosomal RNA (rRNA). The genes in the nucleus are in chromosomes. A chromosome consists of a molecule of DNA (two after replication of the DNA) and associated proteins.Genes are segments of DNA molecules. A single DNA molecule has numerous genes. For example, humans have 23 chromosomes and about 20,000 to 25,000 genes in a haploid set, so there are, very roughly, a thousand genes on an average chromosome, which is to say along an average molecule of DNA. Genes in mitochondria and chloroplasts are on loops of DNA, like prokaryotic chromosomes. Mitochondria have 37 genes, some of which encode polypeptides, while the others code for rRNA and tRNAs. Chloroplasts have more than this (over 120 in one liverwort).
Are chromosomes a DNA molecule with many genes?
Yes, because chromosomes are full of genes and DNA
30 How is information stored and coded in DNA and genes?
DNA is a molecule composed of four bases: adenine, thymine, cytosine, and guanine. These bases are arranged in a specific sequence to form genes, which are segments of DNA that code for specific proteins. The sequence of bases in genes serves as instructions for cells to produce proteins, which in turn carry out various functions in the body.
What molecule carries out our genes?
DNA molecules carry out our genes.
What parts of the DNA molecule that determine heredity?
Genes
Are DNA and genes the same thing?
No, DNA and genes are not the same thing. DNA is the molecule that carries genetic information, while genes are specific segments of DNA that code for specific traits or characteristics.
What part of a DNA molecule is responsible for the genetic code?
The genes present in a DNA molecule are responsible for the genetic code. Within the genes, the exons specifically are the coding regions.
What is the relationship between chromosomes and genes and between genes and DNA?
Chromosomes are structures made of DNA that carry genes. Genes are segments of DNA that contain the instructions for making proteins. DNA is the molecule that carries the genetic information needed for the development, functioning, and reproduction of living organisms.
How many molecules of eukaryotic DNA make up a chromosome in humans?
A chromosome in humans is made up of one long DNA molecule. This DNA molecule is double-stranded and contains thousands of genes.
What molecule genes contain the instructions for building?
The DNA molecule contains the genes for the construction of protein molecules.Genes contain instructions for building proteins.
Explain how DNA genes and chromosomes are related?
DNA is the molecule that genes are made of. Chromosomes are the (arbitrary) clumping that genes form in cells.
Do miroorganisms have genes?
Yes but they don't have a core in their cells where the DNA can be stored.
Are genes and DNA the same thing?
No, genes are segments of DNA that contain instructions for making proteins, while DNA is the molecule that carries genetic information in all living organisms.
