What were Mendel's conclusions about how traits were passed from gen. to gen?
They follow certain predictable patterns. Controlled by discrete units, now called genes. Factors occur in pairs and members of each gene pair sep. from each other during gamete formation.
What is the chromosome theory of inheritence and how is it related to Mendel's findings?
it was based on parallels between mendel's model of heredity and behavior of chromosomes. thates that inherited traits are controlled by genes residing on chromosmes that are transmitted by gametes
What are alleles? If individuals carry genes in pairs, is it possible for more than to alleels of a gene to exist.
A gene variant is called an allele. There can be many such varients in a pop, but for a diploid org, only two such alleles can exist in any given individual.
Contrast genes and chromosomes
Genes are linear sequence of nucleotiedes, unsually exert influece by producing proteins through the process of transcription/translation. functional units of heredity. Assosciate sometimes with proteins to form chromosomes.
How is genetic informatin encoded in a DNA molecule?
encoded by the sequence of bases. This sequence is transcribed into RNA products, which are then translated into proteins
Describe the central dogma of molecular genetics and how it serves as the basis of modern genetics
Cent. dogma refers to relationships among DNA, RNA, and proteins. Must understand transcription and translation to understand these relationships.
How many different proteins, each with a unique amino acid sequence, are possible in a protein that is five amino acids long?
If a protein chain is five amino acids long at each position, there can be twenty amino acids, therefore, there would be 20^5 diff. possible combos
