How many nitrogen bases make up a codon and what does it represent?

Answers

3 bases make up a codon that specifies for a specific trait.

Final answer:

A codon is made up of three nitrogen bases in an RNA molecule, each coding for a specific amino acid. It is an essential concept in understanding the production of proteins.

Explanation:

A codon in the biological context consists of three nitrogen bases. These nitrogenous bases are part of an RNA molecule. The bases can be adenine (A), guanine (G), cytosine (C), or uracil (U). Each codon represents and codes for a specific type of amino acid. As a result, a sequence of codons provides instructions for the construction of a protein. This is vital to understanding the central dogma of molecular biology—DNA makes RNA and RNA makes protein.

Who has hemophilia in the pedigree that is shown? John and Ann Fred and Luke John, Charles, Jack, and Irene Ann and Marie

Answers

From the information provided in the pedigree, it is not explicitly stated who has hemophilia. The presence of hemophilia in the pedigree is not mentioned next to any individual's name. Additional information would be needed to determine which individuals have hemophilia in the given pedigree.

A. In a purebred tall plant, what gametes are possible?

Answers

A dwarf is a recessive trait. In order for the plant to be shorter, it would have to have 2 recessive alleles. The plant is also purebread so it wont contain the tall allele. The gametes that are possible are tt.

What do you mean by gametes?

A gamete is a reproductive cell of an animal or plant. In animals, female gametes are called ova or egg cells, and male gametes are called sperm. Ova and sperm are haploid cells, with each cell carrying only one copy of each chromosome. During fertilization, a sperm and ovum unite to form a new diploid organism.

Moreover, the term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diploid cells.

Therefore, the primary function of gametes is to carry out fertilization in sexually reproducible organisms. During fertilization, a male gamete (sperm/spermatozoa) fuses with female gamete.

A fertile hypha that bears spores is called a?

Answers

a fertile hypha that bears spores is called a sporangiophore. basically, it's a vertically shaped hypha that hold a chamber filled with the spores, and once it's ready it lets the spores out :)

Don't choose the other answer unless you want to be wrong!

The correct answer is:

conidiophore

This is what the lesson says:

Reproduction among the fungi can occur both asexually and sexually. Asexually, fungi can reproduce by fission, fragmentation, budding, and producing spores. Spores are common reproductive structures among fungi. These spores can be carried by the wind, giving the stationary fungus the ability to spread its offspring over great distances. Molds reproduce by spores. A fertile hypha that bears spores is a conidiophore.

A lava field could someday be a diverse temperate forest!

True
False

Answers

There is a remote possibility a barren rock could turn into a temperate forest, but this would have taken billions of years. It is not likely to have happened therefore I would have to say the answer is false.
