An individual having two different alleles of a specific gene is described as being _________ for that specific trait.
An individual having two different alleles of a specific gene is described as being Heterozygous for that specific trait.
You have a heterozygous genotype for that gene if the two versions differ. Being heterozygous for hair color, for example, means you have one allele for red hair and one allele for brown hair. The interaction of the two alleles influences which traits are expressed.
Being homozygous for a gene means you inherited two identical copies. It is the inverse of a heterozygous genotype, in which the alleles differ. People with recessive characteristics, such as blue eyes or red hair, are always homozygous for that gene. In genetics, heterozygous means having inherited different versions (alleles) of a genomic marker from each biological parent. As a result, a person who is heterozygous for a genomic marker has two distinct versions of that marker.

When dna is copied, sometimes one or more of its nitrogen bases are copied incorrectly. How do you predict that a change to a single nitrogen base, such as an adenine or an thymine, could affect the function of a gene? use science reasoning to support your prediction.
When a nitrogen base is changed it can affect the function of a gene by being transcribed into a non-synonym codon and therefore also being translated into a distinct protein.
Mutations also result from the addition of one or more bases, known as an insertion, or the removal of one or more bases, known as a deletion.
When one DNA molecule is copied to make two DNA molecules, each new DNA contains 100% of the parent DNA. DNA replication uses each strand of a DNA molecule as a template and create the new strand of DNA. These mutation can also alter in the nucleotide (DNA) sequence of the genome of an organism.

how would the hedgehog pathway likely be affected if ift-a trafficking was disrupted in the presence of hedgehog ligand? group of answer choices
The correct answer is that Ptch1 and Smo would both be found in the primary cilium.
The Hedgehog signaling route is a signaling pathway that provides embryonic cells with the information they need to differentiate properly. Hedgehog signaling proteins are present in various amounts throughout the embryo.
When the SHH ligand attaches to the transmembrane protein PTCH1, the SHH pathway is triggered, which then activates the pathway. As a result of this interaction, smoothened (SMO) is released and its downstream genes are activated, which ultimately results in the expression of the oncogene Gli-1, which encourages cell division and aids in the development of tumors.
From the cell membrane to the nucleus, it is a highly conserved evolutionary pathway for signal transmission. The Hh signaling pathway is crucial to the development of the embryo.

If a nucleus has eight chromosomes during interphase, It will have eight chromosomes during metaphase.
The interphase and the M (mitotic) phases of the cell cycle follow this progression. The first includes mitosis and cytokinesis, while the second includes G1 (the first gap), S (synthesis), and G2 (the second gap).
"everything in a cell's life not involving division" is a fundamental definition of interphase. Instead, cells multiply many of their own contents and become larger as a whole. The genetic material of a cell is only duplicated or replicated during its own interphase stage.
Metaphase: Each daughter nucleus will receive an identical chromatid because the chromosomes are aligned in the middle of the cell along the metaphase plate, with one chromatid on each side.

The majority of proteins contain a uniform positive charge, and a uniform neutral charge, and most proteins have intricate three-dimensional structures that might affect how well they travel through the gel electrophoresis. For these reasons, proteins need to be denatured. Here, the right answers are A, B, and D.
Protein separation is accomplished using a molecular technique called sodium dodecyl sulfate-polyacrylamide gel electrophoresis, which operates in the proximity of an electric charge. Proteins are separated using SDS-PAGE according to their electrophoretic mobility. Protein charge, shape, and structure all affect electrophoretic mobility.
To proceed in the direction of the positive terminal, the protein molecules need to have a constant negative charge (anode). The overall charge of a protein is determined by the amino acid content of the protein as well as the charge of the individual amino acids.
Thus, depending on the total makeup of amino acids, the charge may change. Depending on the ratio of different amino acids, the total charge of the proteins can be positive, negative, or neutral. The SDS treatment gives the proteins a consistent, negative charge. Then, according to size, the negatively charged amino acids flow toward the positive terminal.
