Genotyping determines differences in genetic complement by comparing a DNA sequence to that of another sample or a reference sequence. It identifies small variations in genetic sequence within populations, such as single-nucleotide polymorphisms (SNPs...
What is the function of the head of the sperm? By Zaira Salvador B.Sc., M.Sc. (embryologist). The head is the most important part of the spermatozoon, as it contains the genetic material of the gamete inside the nucleus. This genetic material or DNA is the sign of identity of the...
What is a DNA sweep? What is the basic structure of DNA? What is DNA polymerase made of? What is made during DNA translation? What are the sides of DNA made of? What is global DNA methylation? What if DNA gyrase would stop working? How it would influence the DNA sequence?
Later, scientists discovered that DNA was responsible for heredity and found that genes are the sequences in DNA that encode proteins and functional RNAs. It seemed that genomes were organized so that a given piece of DNA would encode a specific protein, and this is the way genes were ...
1要考试了,非常急···1.data from a DNA analysis has been lost.The base composition was A=27%,G=23%.What is the amount of G and T in this DNA molecule?2.what is the purpose pf making an RNA copy of a DNA sequence coding for a protein?3.how does DNA replication occur in ...
Thepromoter, a DNA sequence that liesupstreamof the RNA coding region, serves as an indicator of where and in which direction transcription should proceed. The promoter is not actually transcribed; its role is purely regulatory. While promoters vary tremendously among eukaryotes, there are some comm...
If one strand of a DNA double helix has the sequence TCGAGTCCGG, what is the sequence of the other DNA strand? Consider the DNA sequence: CCCTTAGATGGA What is the second strand sequence that pairs with this sequence? If the 3' to 5' strand of...
Straight away, you're probably intuiting some of the strengths and weaknesses of strict verbatim transcription. Strict may be ideal for an exchange where emotional nuance is as important as what was said — for example, a customer feedback interview. However, this approach would be inappropriate...
This section provides a quick introduction of gene, which is a section of a double helix DNA structure that contains a specific sequence of base pairs representing a specific coded instruction to construct building blocks for living organisms.©...
Transcription is a process that occurs in all living cells. During transcription, strands of RNA are created based on the DNA found within the cells. When a strand of messenger RNA (mRNA) is created, it is then used to produce proteins during translation. A whole strand of DNA is not ...
