The very long strand of DNA which further contains many genes (hundreds to thousands) makes up a chromosome. The genes are arranged in a particular sequence and have a particular location on the chromosome (called its locus). In addition to DNA, chromosomes also contain man...
Genotypes can be either homozygous or heterozygous. When the two inherited alleles for a given gene are identical, this specific gene is calledhomozygous. Alternatively, when the two genes are different, the gene is said to be heterozygous. Dominant traits require the presence of only one allele ...
What is an Allele? Sometimes, there are different forms of genes from the same person. These are calledAlleles(say a-leel). To make this easier, let us use specific examples. Let us say you have blue eyes. It would be very likely that your mum or dad also had blue eyes. If even ...
This process is facilitated by genes, which are DNA sequences located on the chromosomes.Answer and Explanation: DNA is a double stranded polynucleotide polymer that comprises of long antiparallel chains of nucleotide monomers. The monomer has three main parts: a...Become a member and unlock all ...
called this proposal the sequence hypothesis (Crick, 1958); other scientists have since referred to it as the genes-on-a-string hypothesis. In Crick's words, this hypothesis "assumes that the specificity of a piece ofnucleic acidis expressed solely by the sequence of its bases, and this ...
Briefly describe what you know about the structure of DNA and how DNA is packaged in a cell. What is the part of the cell cycle in which DNA is synthesized? How many different kinds of bases can be found in the DNA? What is a single-ring nitrogenous base found in DNA called?
A penis that never forms, is tiny, or resembles a large clitoris A urethral opening at the base of the penis, not at the tip A little, open scrotum that could be mistaken for labia Testicles that don’t descend Depending on when genital development gets interrupted and what caused it, sy...
We can also learn about evolution by examining the similarities or differences in DNA between species, and as a result, we can see which genes remain the same and which change over time. Comparing DNA tells us about the evolution of our species. As life forms evolve, their DNA changes. Mu...
Gene is nucleotide sequences with genetic information that is inherited by offspring. Genes are responsible for traits or characteristics in an individual. Each gene for each trait has two forms called alleles. Answer and Explanation:1 Expressed genes are those that can be transcribed and translated...
Similar to the way that letters in the alphabet can be arranged to form words, the order of nitrogen bases in a DNA sequence formsgenes, which, in the language of the cell, tell cells how to makeproteins. The shorthand for this process is that genes "encode" proteins. ...
