Explain why the sequence of dna bases is just like a sequence

Biology

Westkost [7]3 years ago

DNA is nothing more than a sequence of bases (nucleotides) and since DNA is normally double stranded, they can be referred to as base pairs. One could best visualise it like a zipper: two connected strands (that can also be separated). DNA is made up of only four different bases, abbreviated as A, C, G and T. These always form the same pairs: A on one side of the zipper, T on the other side and the same goes for C and G. So, when unzipped, you always know the sequence of the opposite strand.

The sequence of base pairs that make up our DNA should be viewed like a bar code. Every set of three bases code for one building block of a protein. That's all that DNA is for: code for building proteins. A set of three bases is called a codon and tells machinery in the cell (ribosome) to add one specific building block to a forming protein. It's like Lego and DNA is the instructions that tell you which block to add next.

These different blocks give shape and function to the proteins it helps to build.

Describe two inheritance patterns besides simple dominance
Phantasy [73]

Explanation: All of it is in gamete formation. Meaning, it is going through a gamete formation which also means that pairs of alleles that are for different traits, segregate. They move on independently from one another, never touching.

For your question, It's incomplete dominance which is when cases with one allele isn't complete to be dominant over another allele. It's all got to come together in order for it to become a strong and dominant allele, or else it won't be complete and won't become and do what it has to.

I hope this help you and I hope that I gave you what you wanted/needed for this question.

What is the maximum number of electrons that can be placed in the first shell/energy level?
zysi [14]

QUESTION:-

What is the maximum number of electrons that can be placed in the first shell/energy level?

A. 1

B. 8

C. 2

D. 18

Answer:

C. 2

The first shell, closest to the nucleus and with the lowest-energy electrons, is shell 1. This first shell has only one subshell (labeled 1s) and can hold a maximum of 2 electrons

Match each word or phrase with its definition. Note that not all definitions will be used. - Polygenic traits - Quantitative tra
shepuryov [24]

Answer:

A. An undifferentiated cell that has not yet been programmed and can become any type of cell = Stem cell

C. Traits that are influenced by more than one gene = Polygenic traits  

F. Genetic engineering that exactly duplicates an organism = Reproductive cloning    

G. Identical twins = Monozygotic twins  

H. Making mRNA from DNA = Transcription

J. A change in the DNA sequence = Mutation  

K. Fraternal twins = Dizygotic twins  

L. Thirteen DNA sequences that all humans carry = Short tandem repeats  

M. Traits that involve the actions of many genes but also interact with the environment = Quantitative traits

N. Uses ribose as the sugar in the nucleotide = Ribonucleic acid

Explanation:

Stem cells are undifferentiated cells that are capable of self-renewal or differentiation into many different types of cells. Polygenic traits are phenotypic traits influenced by two or more genes, while quantitative traits are phenotypic features controlled by the combined effects of many genes and environmental factors. Reproductive cloning is a laboratory technique used to produce genetically identical individuals from mature somatic cells. Monozygotic twins are identical twins obtained by fertilization of a single egg cell which then splits in two, while dizygotic twins are generated by fertilization of two different eggs. Transcription is the process where the genetic information contained in a strand of DNA is copied into a particular type of RNA (mRNA, tRNA, ncRNA, etc). A mutation is a genetic alteration in the DNA sequence of a cell of a living organism that is produced during DNA replication. Short tandem repeats (STRs) are repeated DNA sequences (2-16 nucleotides, two or more times) that are adjacent to each other. In humans, there are 13 well-characterized STR sequences known to be associated with populations of different ethnic groups.
