What part of a DNA molecule contains the instruction of making chromosome packaging proteins?
In prokaryotes the genes directly specify proteins.In eukaryotes the exons within the genes specify proteins, the introns within the genes are noncoding DNA that alternate with exons and are spliced out in the process of transcription to messenger RNA.
How many genes does it take to code for mouth size?
The genetic basis of mouth size is complex and not determined by a single gene. Instead, it involves multiple genes that interact with environmental factors. Studies suggest that variations in several genes can influence traits like mouth size, but the exact number can vary widely among species and populations. Therefore, it is difficult to specify a definitive number of genes responsible for mouth size.
Are functional units of heredity that are composed of DNA and specify the structure of proteins.?
Yes, functional units of heredity that are composed of DNA and specify the structure of proteins are called genes. Each gene contains the instructions needed to produce specific proteins, which play crucial roles in the structure and function of an organism. These instructions are encoded in the sequence of nucleotides within the DNA. Genes are fundamental to the processes of inheritance and the expression of traits in living organisms.
What is an example of a constitutive gene or set of genes and why is it important?
Housekeeping genes, such as those involved in basic cellular functions like metabolism or DNA replication, are constitutive genes that are continuously expressed in all cells. These genes are important because they provide the foundation for essential cellular processes to occur, ensuring the normal functioning and survival of the organism.
Are master genes and homeotic genes the same thing?
Master genes and homeotic genes are related but not the same. Homeotic genes are a specific type of master gene that regulate the development of anatomical structures in organisms, determining the identity of body parts. Master genes generally refer to genes that control the expression of other genes and play crucial roles in regulating developmental processes. Thus, while all homeotic genes are master genes, not all master genes are homeotic genes.

Two chromosomes in a nucleus that carry genes for the same traits in the same places but specify different versions of the same traits are called?
Homologous Chromosomes.
Why are Hox genes thought to play an important role in the development of different morphologies?
Hox genes are important in development because they regulate the body plan of an organism, determining where and when body structures will form. They are highly conserved across species and control the identity of body segments along the anterior-posterior axis. Mutations in Hox genes can lead to significant changes in morphology and development.
Are polygenic genes dominant genes?
Polygenic genes are usually dominant genes.
The triplet codes needed to specify a specific polypeptide chain are found in the?
The triplet codes needed to specify a specific polypeptide chain are found in the mRNA (messenger RNA) during the process of translation. These triplet codes, known as codons, determine the sequence of amino acids that will be incorporated into the polypeptide chain.
Does prokaryotes have genes?
Of course they have genes. They need genes for survival and reproduction.
Do dominant genes affect recessive genes?
The dominant genes take over, and then the recessive genes hide away
Are linked genes genes located on the same chromosome?
Yes, linked genes are genes located on the same chromosome.
Are master genes and homeotic genes the same thing?
Master genes and homeotic genes are related but not the same. Homeotic genes are a specific type of master gene that regulate the development of anatomical structures in organisms, determining the identity of body parts. Master genes generally refer to genes that control the expression of other genes and play crucial roles in regulating developmental processes. Thus, while all homeotic genes are master genes, not all master genes are homeotic genes.
Which genes are dominant and which are recessive?
Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.
